Various remote-controlled methods have been developed to improve operability using force or visual assists; however, using only force or visual assists may deteriorate the operability or safety performance. Therefore, a remote-controlled method with both force and visual assists is proposed to improve the operability while maintaining safety performance. The proposed remote-controlled system consists of a wheeled mobile robot, control device, and monitor. The force assist is generated using the time to collision (TTC), which is the predicted time of collision of the mobile robot against an obstacle. This force assist is applied to the operator using a control device to achieve collision avoidance. Using a visual assist, a predicted trajectory for the mobile robot based on the TTC is generated. For operability improvement, this predicted trajectory with color gradation is shown on the monitor. In summary, the achievement of operability improvement while maintaining safety performance is confirmed from experimental results using the proposed method.

This paper proposes a local path planning method based on virtual manipulators and dynamic window approach (VMDWA) for a wheeled mobile robot. In the conventional researches such as the dynamic window approach (DWA), the mobile robot follows the desired path and avoids obstacles in the dynamic and static environment. However, DWA calculates the predicted path assuming the constant velocities. From these predicted paths, the best path is selected using the cost function. Since the DWA assumes the constant value of velocities, multiple candidates of paths cannot generate flexible movements. Therefore, it may not be possible to generate the path that does not collide with obstacles. To solve these problems, this paper proposes the local path planning method based on virtual manipulators and dynamic window approach (VMDWA). In the proposed method, virtual manipulators are taken into account at the calculation of the path planning based on DWA. Therefore, it is possible to use the variable velocities values for the predictive paths. VMDWA selects the optimal path from the several calculations of predictive paths. The simulation results confirmed the effectiveness of the VMDWA.

This research focuses on an adaptive control method for a pulling motion of a fibril. From the viewpoint of the biotechnology, analyses of a mechanical characteristic of a fibril are important. For the analyses, the pulling motion of the fibril is conducted by a piezoelectric actuator with a cantilever. The fibril is attached at the tip of the cantilever, and is pull by the piezoelectric actuator. By this pulling motion, it is possible to measure the mechatronic parameters of the fibril. During the pulling motion, the mechatronic parameters of fibril are changed due to the pulling force. Therefore, it is hard to conduct the pulling motion at the desired force command such as the constant force. From this view point, this paper proposes the adaptive control method based on the recursive least squares algorithm (RLS). These mechanical parameters are estimated in real-time by RLS. By using these estimated parameters, the position command to achieve the force command is calculated. In the simulation, the proposed method is implemented, and the pulling motion with the contact force is simulated. The validity of the proposed method is confirmed from the simulation results.

- Remote Control Method with Force AssistBased on Collision Prediction Calculatedfrom Each Turning Radius in Mobile Robot
This paper proposes the remote control method with the force assist based on the collision prediction calculated from each turning radius in a mobile robot. The remote control system consists of the control device and the mobile robot. By using the force assist in the remote control system, the operator recognizes the environmental information as the tactile sensation. For the realization of the force assist, the environmental information has to be transmitted from the mobile robot to the control device. In addition, the precise force assist is achieved from the high resolution environmental data. However, the communication time delay occurs by increasing environmental data. From this viewpoint, this paper proposes the data compression method based on the collision prediction. This collision prediction is calculated from the environmental information and the prediction trajectory of each turning radius. Not the whole environmental data but the collision prediction for each prediction trajectory is sent from the mobile robot to the control device. As the result, the amount of the data is drastically decreased. In addition, it is possible to realize the force assist having the almost same performance as the conventional method. The validity of the proposed method was confirmed from the experimental results.

- Tracking Control Method Considering Obstacle Avoidance by Reflective Motion for Mobile Robot
This paper proposes a tracking control method considering an obstacle avoidance by a reflective motion for a mobile robot. In the mobile robot, a laser range finder is utilized to recognize environmental information. The obstacle avoid motion is created by using environmental information and the virtual manipulators mounted on the mobile robot. In the conventional researches, the flexible obstacle avoidance method by using the kinematic relation between the virtual manipulators and environmental information was reported. This method has the advantage for the calculation cost and flexibility like reflective motion. However, the robot may not follow the desired trajectory after the obstacle avoidance, since this conventional method is based on the velocity control. In order to solve this problem, this paper proposes a combination method of the tracking control and the obstacle avoidance. Considering the velocity limits of the tracking control, it is possible to modify the priority of the trajectory tracking and the obstacle avoidance. The effectiveness of the proposed method was confirmed from the experimental results.

This paper proposes the position tracking control for a 2-link manipulator with a bi-articular muscle. The 2-link manipulator with the bi-articular muscle is designed by using the epicycle gear. This 2-link manipulator has the redundancy, since this has the not only the mono-articular muscle but also the bi-articular muscle. Therefore, it is necessary to implement the particular control method for its redundancy. In order to solve this redundancy, phase different control (PDC), which is based on electromyogram of each muscle, has been reported. This paper proposes PDC combined with the workspace observer. By using the proposed method, the error between the force reference and the force response due to the linearization is compensated. In addition, the modeling errors are also compensated. As a result, the high precision motion control based on the musculoskeletal model of the upper arm is achieved. The effectiveness of the proposed method was confirmed by the simulation and experimental results.

This paper describes the experimental operability evaluation of a remote control method with a force feedback for a mobile robot. By using the force feedback in the remote control system, it is possible to recognize the environmental information as the tactile sensation. In the conventional remote control methods, the force feedback is generated based on the geometric position relation between the mobile robot and environment. On the other hand, this paper shows the force feedback based on the collision prediction. The steering type control device with the tactile force feedback is utilized. In addition, the visual sensor is added to the remote control system for the visual feedback. Therefore, the operator manipulates the control device based on the visual and tactile information. In order to evaluate these remote control methods, the experimental results by 5 subjects are shown. The operability improvement by using the remote control method based on the collision prediction was experimentally proved.

This paper proposes the improvement method of operability in a bilateral control by using visual information. The bilateral control system consists of a master system which is manipulated by the operator and a slave system which contacts remove environment. Considering the actual use of the bilateral control, the operator manipulates the master system while watching the visual information from the slave side. In this situation, there is the time delay of visual information. This time delay has the bad influence of the operability. In order to improve the operability, the synchronization method of visual and tactile information is described. The virtual model, which consists of the virtual slave model and the virtual object model, is proposed to compensate this time delay. This virtual model is overlaid on the visual image from the slave side. As a result, the operator grasps the motion of the slave system and the object without time delay. The validity of the proposed system was confirmed from the experimental results.

The powertrain of electric vehicles in the market has a problem in that its performance degrades because of fluctuations in battery voltage. In order to solve this problem, this paper proposes an energy conversion system to boost a part of the electric vehicle battery voltage. This system consists of the existing electric vehicle powertrain and a bi-directional isolated DC-DC converter called the dual active bridge (DAB). This system is able to compensate for battery voltage drops with high efficiency by using a small capacity DAB converter. In addition, a control method for the DAB converter is proposed. This control method achieves a better response to the transient state than conventional methods. The validity of the proposed system and its control method are confirmed by simulation and experiments. A high efficiency of about 99% is obtained from the experimental system prototype.

In recent years, there have been several studies on human-machine cooperative systems. These systems involve contact between humans and the environment. Therefore, it is necessary to create a safe system in order to avoid injuring humans and the environment. On the other hand, task realization is also important. From this viewpoint, a force-based compliance controller with a force threshold is proposed in this paper. This controller achieves both task realization and adaptation to the environment. This motion selection is conducted by comparing the force command and a force threshold. In addition, a human-machine cooperative grasping/manipulating system using the proposed controller is developed. This system can conduct a human-machine cooperative motion, which consists of an autonomous motion and a human-assisting motion. The priorities of the autonomous motion and the human-assisting motion are easily designed by changing the force thresholds. The validity of the proposed system is confirmed with experimental results.

This paper describes a remote control system with a virtual force feedback in a mobile robot. In the mobile robot, a laser range finder is utilized to recognize environmental information. By using this environmental information and the specification of the mobile robot, the safety velocity area (SVA) is calculated in real-time. On the other hand, an operator generates the velocity commands for the mobile robot in real time. By using the relation between SVA and the velocity commands, the virtual force is generated. If the velocity commands are out of SVA, the operator can feel the virtual force. In the previous research, the virtual force is generated based on the only velocity differences. Therefore, the chattering of virtual force commands may occur. In order to solve this problem, this paper proposes the virtual force generation method with hysteresis. Therefore, the operability of the remote control system is increased. From experimental results, the validity of the proposed method was confirmed.

This paper proposes a synchronization method of visual and tactile information by using a virtual slave model in a bilateral control. Considering an actual remote-operated system, an operator operates a master system while watching visual information that is sent from a slave side. However, transmission of position, force, and visual information has communication delay. This is because the slave system on the image moves later than the actual slave system. This communication delay gives a bad effect on operability in the bilateral control. Therefore, the synchronization method of visual and tactile information is important. From this viewpoint, visual and tactile information in bilateral control is synchronized by using the virtual slave model. This virtual slave model is overlaid on the image from the slave side. The operator operates the master system while watching the virtual slave model overlaid on the image. As a result, the operability is improved, since the virtual slave model helps the communication delay of visual information. The effectiveness of the proposed system was confirmed form the experimental results.

This paper proposes a real-time modification method of position and force teaching information in a human-robot cooperative system. In this study, human motion is recorded using bilateral control to obtain position and force teaching information. When the recorded information is reproduced, a human operator can add an operation to modify the teaching information. Because of the ability to modify the teaching information, it is possible to create variations in the motion to accommodate environmental changes. On the other hand, without the modification by the operator, the original recorded motion is achieved. In the proposed method, the operator focuses on modifying the teaching information in order to realize the desired motion. The validity of the proposed method is confirmed by experimental results.

Many researchers have studied electric vehicles (EVs) for improving their efficiency to increase the driving range. The system design of an electrical power train has significant influence on the total driving range per charge and has been widely researched. A series chopper power train using a buck-boost chopper has been proposed as an electrical power train system. This electrical power train achieves high efficiency due to low and high inverter input voltage in the low and high speed regions, respectively. In previous studies, a high efficiency control optimizing the chopper output voltage was proposed, and a motor test bench with characteristics similar to actual EVs was constructed by using a battery emulation system with voltage variation characteristics, which occur due to the state of charge (SOC) and internal resistance. This paper shows the effects of optimizing the chopper output voltage on the driving range per charge in both efficiency estimation and the motor test bench experiment. This allows the verification of the usefulness of optimizing the chopper output voltage for increasing the efficiency. The results indicate an improvement of 0.9% and 2.7% in the driving range per charge during efficiency estimation and the motor test bench experiment, respectively.

This paper proposes an implementation method of a workspace observer (WOB) considering a fluctuation of an equivalent mass matrix. WOB is one of useful methods to achieve robust control systems. The stability and transient response of WOB is influenced from a modeling error of a nominal plant model. For a high performance of WOB, a precise modeling of a nominal plant model should be used. From this viewpoint, this paper modifies a nominal plant model in real time due to an estimation of an equivalent mass matrix. Here, a nominal plant model includes off-diagonal elements. An equivalent mass matrix is fluctuated due to a manipulator motion. This fluctuation is influenced to a control performance of WOB. Therefore, this fluctuation is compensated in this paper. In addition, a decoupling in an acceleration dimension is actualized, even if a nominal plant model includes off-diagonal elements. The validity of the proposed method was confirmed by simulation results.

This paper proposes a task realization method by using a force-based variable compliance controller for flexible motion control systems. In recent years, the robots working in human life space are desirable. Considering the robots working in human life space, they should achieve the safety motion. From this viewpoint, one of the key technologies is flexible motion control system. Of course, task realization instead of human beings is important. Therefore, it is necessary to propose the realization method of several tasks for the flexible motion control systems. In this paper, two robot tasks are defined: "approach task" and "pushing task." The approach task is the motion for a robot to approach an environment and not to contact the environment. On the other hand, the pushing task is the motion for the robot to contact and push the environment in order to achieve the several tasks. For the realization of the several tasks to the environment, it is necessary to achieve both the position control during the approach task and the force control during the pushing task. Therefore, the controller has to be modified depending on the contact state, which means whether the robot is in contact with the environment or not. In order to modify the controller, the variable compliance gain which is varied according to the contact state is proposed. Focusing on the approach task, the position control which is equivalent to the conventional position-based compliance method is achieved by using the proposed method. On the other hand, the proposed controller is suitable for the pushing task compared with the conventional position-based compliance controller since the proposed controller is based on the force control. Therefore, several tasks which include the position tracking and the contact with the environment are actualized by using the proposed method. In addition, the performance analysis by a Bode diagram and stability analysis by root loci are conducted. The validity of the proposed method is confirmed from the experimental results.

In order to perform intelligent tasks using a tool, it is necessary to estimate the relation between a robot system and the tasks. However, no estimation method for this relation is currently available. Therefore, this paper proposes an estimation method for this relation by using an external sensor. In this paper, the hybrid control method based on the oblique coordinate system is utilized. Then, this relation can be treated as a task Jacobian matrix. By using the proposed method, it is possible to estimate the correct task Jacobian matrix, even if the kinematic relation between the robot system and the tool is not known or is changed during the task. As a result, the tasks are performed with this tool. From the simulation and the experimental results, the validity of the proposed method was confirmed.

This study investigates the influence of the equivalent mass fluctuation on the control performance of a workspacebased motion control system with a workspace observer. It is theoretically demonstrated that the equivalent mass fluctuation affects the control gain, the cut-off frequency of the workspace observer, and so on. In addition, the effectiveness of the workspace motion controller based on the estimated equivalent mass with the workspace observer is discussed. In order to verify the workspace-based control method with the estimated equivalent mass, some simulation and experimental results obtained with the workspace position control of a two-degrees-of-freedom planar manipulator are presented. © 2014 The Institute of Electrical Engineers of Japan.

This paper investigates a design method for an equivalent mass matrix in motion control based on workspace observer. The equivalent mass matrix implemented in the control system is often designed as a diagonal matrix. On the other hand, a real equivalent mass matrix includes non-diagonal elements. Conventionally, assuming the cut-off frequency as infinity, these elements is ignored. However, actually, since the cut-off frequency is not infinity, the non-diagonal elements can not be ignored. Therefore, in order to improve the control performance, it may be necessary to implement the equivalent mass matrix including the non-diagonal elements. From the background, the experimental comparison about the equivalent mass matrix design is conducted.

In this paper, the experimental platform using motor test bench with same environment as the actual vehicle is developed. In the previous paper, the experiments were performed by using motor test bench[2]. These experiments were performed under the condition of the constant DC-supply voltage. However, the output voltage of the battery used in the actual EV is changed depending on the state of charge (SOC). Furthermore, flux weakening control was not applied to the inverter at the previous motor test bench. This is why exactly one charge driving range could not measured. In order to solve these problems, this paper develops the experimental platform (motor test bench) with following two things; 1) construction of the battery emulation system, and 2) adaptation of the flux weakening control to the inverter. The experiments was implemented for verification of the validity of the experiment platform (motor test bench). From these experimentalal results, it was confirmed that the experiment platform (motor test bench) can simulate the actual vehicle.

This paper proposes a prediction method considering object motion for a humanoid robot with a visual sensor. A visual servo control method is one of the useful methods to control the robot based on visual information. Robot can track the movable object by using this method. However, this system does not consider the future response of the object motion. As a result, the delay arises. In order to solve this problem, it is necessary to predict the object motion from the visual information. This paper proposes the prediction method considering object motion based on visual servo system. By using this method, the robot predicts the goal position which is the stop position of the movable object. Thereafter, the robot walks to the above prediction position. The robot moves to goal position without useless trajectory. The experiments with this prediction control method are conducted to confirm the validity of the proposed method. From these results, the validity of the proposed method is confirmed.

Authors proposed the series chopper based power train aimed for the extension of the driving range. In previous paper [1], under the condition of the constant DC-supply voltage, effectiveness of the optimization of the profile of the chopper output voltage was shown. However, the output voltage of the battery used in the actual EV varies depending on the state of charge (SOC). Because of this difference, the precise comparison of the power train was not performed. In this paper, by emulating the battery including the internal resistance and output voltage dependency on SOC, the driving range is compared in the motor test bench. It is shown that the chopper output voltage adjustment depending on the rotor speed and the weight of the chopper has large effect on the driving range. In comparison to non-chopper power train, the driving range of the series chopper power train increases by 2.1%. In addition, by decreasing the weight of the chopper by a half and zero, the driving range further extends by 1.4% and 3.0%.

Four experiments were conducted using different distances between the camera and object to validate the proposed integration method.

This paper addresses a solution for solving the object's rotational effect during the navigation process by the haptic bilateral control system. The system utilizes the vision-based guidance which depends on the virtual force generated by the vision-based force compliance controller (VFCC). During object's navigation, the virtual force is generated and affected to the manipulator's horizontal trajectory movement. In this paper, the different rotational angle of an object's trajectory which reflects to different movement direction of produced force, will be studied and evaluated. The details concerning the implementation of this method will be discussed. Two sets of experiments are conducted to evaluate the effectiveness of the proposed technique.

In order to assist human beings, the reproduction methods of the recorded human motions have been researched. On these systems, the human motions are recorded as the haptic data (i.e., position, velocity, and force data) by using bilateral control. However, these conventional methods show poor adaptability to the difference in the environmental location during the reproduced phase. In order to compensate this spatial difference, the spatial data processing of the recorded human motions was utilized. On the other hand, the reproduction method of the recorded human motions with time scaling is proposed to compensate this spatial problem in this paper. In other words, the proposed method applies time scaling to compensate the spatial difference. For the realization of the proposed reproduction method with time scaling, the recorded velocity and force data are utilized. By using the proposed method, the physical meaning is clear compared with conventional methods, since power on the certain moment of the reordered task is reproduced. This paper focuses on the point-to-point motion, which includes the force motion and the position motion, as one of typical tasks in the industry field. The validity of the proposed method was confirmed by the experimental results.

This paper proposes a bilateral control for master and slave systems with different degrees of freedom (DOF). In this paper, it is assumed that the number of DOF on the master side is smaller than that on the slave side. In addition, the slave system is divided into slave subsystems according to the number of DOF on the master side. Each slave subsystem accomplishes two kinds of distinctive functions; "task realization by bilateral control between a master robot and a slave subsystem" and "adaptation to environment in contact with a slave subsystem by automation control." The task realization is achieved within the range of the number of DOF on the master side. On the other hand, the adaptation to environment in contact with the slave subsystem is achieved by using the DOF not to be utilized for the task realization. In the results, the proposed controller actualizes both functions. In addition, a human operator can carry out the desired task of the slave system without the consideration of environmental surface. The validity of the proposed method is confirmed by experimental results.

- Development of Grasping/Manipulating System Simulation Platform Considering Collision Model
This paper develops the grasping/manipulating simulation system considering the micro/macro collision model. Previous haptics, especially the bilateral control systems, mainly focused on transmitting the sense of touch and position tracking. In order to expand haptic technology, it is necessary to consider the dynamics motion, such as the impulse force against the environment. For this reason, a collision model is implemented into an environment for a grasping/manipulating simulation system. By applying the collision model, the reaction force, which occurs between the robot and the environment, can be predicted. This implies more accurate interpretation of the dynamics between the robot and the object is available. The simulation platform is confirmed to be valid by comparing the experimental result with the simulation result of grasping/manipulating control. From these results, the relation between the environmental parameters and sampling period of the controller is clarified.

This paper proposes a disturbance observer (DOB) design method for bilateral control systems with multi-degree-of-freedom (MDOF). DOB is one of the robust control methods based on acceleration. DOB uses the nominal mass or nominal inertia for the estimation of disturbance force. A control performance of the bilateral control with DOB is changed according to the design of the nominal mass in DOB. This paper firstly discusses the relationship between nominal mass in DOB and the control performance. Then, the design method of bilateral control with low nominal parameter is proposed. The effectiveness of proposed method is confirmed from the experimental results.

A bipedal robot should be robust and able to move in various directions on stairs. However, up to date many research studies have been focusing on walking in the up or down direction only. Therefore, a strategy to realize walking along a step is investigated. In conventional methods, CoM is moved up or down during walking in this situation. In this paper, a method named as Dual Length Linear Inverted Pendulum Method (DLLIPM) with Newton-Raphson is proposed for 3-D biped robot walking. The proposed method applies different length of pendulum at left and right legs in order to represent the CoM height. By using the proposed method, maximum impact forces are reduced. From the Ground Reaction Forces (GRF) data obtained in the simulations, the validity of the proposed method is confirmed.

This paper proposes a motion control method based on environmental mode for a dual arm robot. By controlling mode information, particular features or trends can be given to robot's motion. Then a distinctive complex motion can be realized. In addition, because environmental mode is information based on the coordinate system which is fixed in the environment, environment-based motion can be realized. Because of these two advantages, it is thought that the proposed method makes a contribution to realization of interactive motion between robots and ambient environment like human being's complex motion.

In this paper, two kinds of evaluation index for the haptic motion analysis in parallel multiple degrees of freedom (MDOF) system are proposed. At first, the spatial modal decomposition method based on discrete Fourier series expansion (DFS) is presented. Spatial modal information expresses a motion element that corresponds to a specific physical action. The spatial modal information can mathematically be defined by the Fourier coefficients. Then, this paper proposes the total harmonic distortion (THD) and the content rate of the haptic modal information as motion evaluation indexes. THD of the spatial modal information can evaluate the complexity of the human motion and/or the deformability of the contact environment. Content rate of the spatial modal information can evaluate the priority of motion element. Some experimental results on the bilateral motion control of a parallel five DOF haptic system are shown, in order to confirm the utility of the proposed indexes.

This paper proposes a new design method for obtaining walking parameters for a 3-D biped robot walking along a step. Many researchers concentrated only on the motion of climbing up or down stairs. However, this study investigates a strategy for realizing walking along a step. In conventional methods, the center of mass (CoM) moves up or down during walking in this situation because the pendulum height is kept at the same length for the left and right legs. Thus, extra work is required in order to bring the CoM up to higher ground. In this study, different pendulum heights are applied for the left and right legs and this method is referred to as the dual length linear inverted pendulum method (DLLIPM). However, when different pendulum heights are applied, it is quite difficult to obtain symmetrical and smooth pendulum motions. Furthermore, synchronization between the sagittal and lateral planes is not confirmed. Therefore, DLLIPM with the Newton-Raphson algorithm is proposed to solve these problems. The walking pattern for both planes is designed systematically, and synchronization between the planes is ensured. Finally, the proposed method is verified by simulation and experimental results.

This paper presents a new haptic bilateral control method with vision-based guidance. The vision-based guidance is realized by the visual force compliance controller which can translate the visual information to assistive force. Integration of an imaging modality effectively further consolidates the servoing procedures. Such information needs to be efficiently rendered to the operator at master system. Particularly, the proposed approach provides real-time visualization and force feedback based guidance for the navigation task. The details concerning the method of implementation of this theory will be explained. Finally, the experimental evaluation of the functionality of this visual compliance controller based on force control is described and discussed.

This paper introduces a method to generate minimal energy joint trajectories during a single support phase of linear inverted pendulum model (LIPM)-based biped walking. By using a variational approach and B-spline curves, this method is able to generate new set of joint configurations. This joint set minimizes the cost function which reduces the energy consumption while keeping the center of mass almost at the same position in x-, yand z-directions. Constraining the center of mass to be the same during minimization helps in conserving the zero moment point (ZMP) of the predefined walking trajectory. The energy consumption function is represented by the actuator's electrical energy which consists of copper loss and mechanical energy. From the simulation results, it is verified that the proposed method is effective.

This paper proposes the design method of the variable compliance gain for the force-based compliance controller considering both position information and force information. The force-based variable compliance controller is effective since it is possible for this controller to realize both the compliant contact motion and the precise position control. However, the chattering occurs at the moment of the controller modification between the position control and the force control. In order to solve this chattering problem, the modification method considering both position information and force information is proposed. As a result, the smooth controller modification between the position control and the force control is actualized. In addition, the position control during the non-contact motion is analyzed by modeling the controller as a second order system. From this analysis, the precise position control is obtained by setting the parameters to achieve a critical damping. The validity of the proposed method is confirmed by the experimental results.

This paper proposes a switching control method to achieve a smooth transition from an edge landing to a sole landing for a legged robot. When a biped robot walks, an undesirable condition at the moment of landing, such as hunting between the ground and the foot, may occur for several reasons. To avoid this condition, this paper focuses on a method that uses simple controllers to ensure a smooth transition from an edge landing to a sole landing. In the event of an edge landing, a force controller should be implemented for a smooth transition to a sole landing. This is because the force controller enables the foot to contact the ground softly. After the landing state is shifted to the sole landing, the control method should be changed to the position controller. Therefore, it is necessary to switch the control method according to the contact condition between the foot and the ground. To avoid the chattering of the controller switching, several hysteresis values are used for the zero moment point (ZMP) position and ZMP velocity in the switching function. Simulations and experimental results confirmed the validity of the proposed method.

This paper proposes the switching control method to realize stable landing for a biped robot. If the landing of the biped robot is unstable, the robot may fall down. Therefore, it is necessary for the biped robot to realize stable landing. In order to achieve the stable landing, force controller should be implemented at the moment of landing. Since force control enables the sole to softly contact the ground. If the landing state becomes stable, control method needs to change position control for the biped robot moving. In other words, the controller should be switched according to the contact condition between the sole and the ground. Therefore, switching control method which consists of position control and force control is proposed. Zero Moment Point (ZMP) is used as index to switch the controller. Position control is applied when ZMP exists in the area around the center of the foot. Force control is used when ZMP exists around the edge of the foot. The validity of the proposed method is confirmed from the simulation results by using the model of inverted pendulum with a sole. © 2012 IEEE.

Recently, a lot of robots and industrial machines with disturbance observer (DOB) have been put to practical use all over the world. By using DOB, acceleration control is achieved. As a result, DOB is contributed to robust position and force control. In other front, DOB is utilized as the reaction force observer (RFOB) for estimation of the external force. As a result, DOB is a key technology for motion control. Therefore, it is necessary to improve the performance of DOB to realize high advanced motion control system. The performance of DOB depends on motion control frequency, current control frequency of motor driver and the resolution of encoder. This paper focuses on motion control frequency and current control frequency.

This paper proposes the force-based variable compliance control method for a bilateral system which consists of master and slave robots with different degree of freedom (DOF). In order to control the bilateral system with this assumption, bilateral control between master and slave robots for task realization and automation control for adaptation to environment in contact with a slave robot are necessary. In this paper, automation control for adaptation to environment in contact with a slave robot is focused on. Considering the automatic control of slave system, the control method should be switched according to the contact condition. In the case of non-contact motion, the position of the slave system is not decided by using the conventional force controller. Therefore, unexpected contact between the slave system and the object may occur. In order to avoid this unexpected contact motion, the position of slave system should be controlled in the case of non-contact motion. When the slave system contacts the object, the force control should be implemented to achieve the stable contact. In this paper, the force-based variable compliance control method is proposed to achieve 2 desired motion. The validity of the proposed method is confirmed by the experimental results. © 2012 IEEE.

In recent years, haptic communication with teleoperation systems has been actively researched. One of the effective methods for haptic communication is bilateral motion control based on acceleration control. If the acceleration-based bilateral control is applied to a parallel multi-degrees-of-freedom (MDOF) system, complicated haptic human motion can be realized in the remote site. However it is difficult to understand whole motion of the system based only on information of each actuator. One of the effective methods for the motion recognition is modal decomposition based on Discrete Fourier series expansion (DFS). This modal decomposition is effective for the analysis of motion of parallel MDOF systems. However, in order to apply the modal decomposition, it is necessary that an arrangement of the parallel MDOF system is known. This paper proposes an arrangement identification method for parallel MDOF teleoperation systems based on Levenberg-Marquardt (LM) method. The method can estimate the arrangement, even if there is no visual information. Finally, the validity of the proposed method is confirmed by the experimental results. © 2012 IEEE.

A bipedal robot should be robust and able to move in various directions on slope or stairs. However, up to date many research studies have been focussing on walking in the up or down direction only. Therefore, a strategy to realize walking along slope is investigated. In conventional methods, CoM is moved up and down during walking in this situation. In this paper, a method named as dual length linear inverted pendulum method with Newton-Raphson is proposed in order to move CoM always in horizontal. Different lengths of pendulums are applied at left and right legs in order to represent the CoM height. By using the proposed method, maximum impact forces are reduced as verified via the simulation results.

In this paper, a task realization method based on modal space considering a tool kinematics is proposed. Modal space is a coordinate system which consists of the position/force tasks. In addition, position/force tasks are transformed from motor information by using task Jacobian matrix. In the conventional method, the various tasks are able to be obtained in the case of setting an appropriate task Jacobian matrix. However, the design method of task Jacobian matrix is not clarified. Therefore, only simple task was realized in the conventional researches. In this research, the design method of task Jacobian matrix is proposed. In order to design the appropriate task Jacobian matrix, kinematics parameters of the tool is put to use. Therefore, the task based on the tool is realized even if the motor configuration is asymmetry. Additionally, the virtual coordinate system is also proposed. The virtual coordinate system is defined at the point on the tool where the designer wants to control. Therefore, the various tasks by using the tool are easily able to be realized. The validity of the proposed method is confirmed by the experimental results.

This paper proposes a manipulability servoing control method in null space for redundant bilateral control systems. In order to bi-directionally transmit vivid haptic sensation between motion control systems, both synchronization of position signals and "action and reaction" law of force signals must simultaneously be achieved. The proposed method adopts modal decoupling method based on Hadamard matrix to bilateral workspace control. Then, this paper investigates the possibility that the proposed method realizes the transmission of haptic sensation and the manipulability servoing between redundant haptic motion systems. In this paper, the effectiveness of the proposed method is confirmed by simulation results and experimental results.

This paper describes the trajectory planning for the pushing motion of a humanoid robot. In the design of a humanoid robot for pushing an object, it is necessary to take into account many parameters such as stride length, pushing force, and walking velocity. However, there are no standard methods for evaluating these parameters. Additionally, the robot may fall down if these parameters are not chosen correctly. In this paper, a method for determining these parameters for pushing motion is proposed. The extended orbital energy (EOE) is considered as the design index. Here, the EOE describes the relation between walking motion and pushing motion. By using the proposed method, the COG trajectory, pushing force and stride length can be modified on the basis of the EOE. In other words, the suitable values of theses parameters can be obtained by determining only the desired EOE. As a result, the humanoid robot walks stably during pushing motion. The effectiveness of the proposed method was confirmed by experimental results.

This paper describes transparency and system connection for future heterogeneous haptic network systems, e.g. bilateral teleoperation systems which include communication networks with different capacities and haptic devices with different degrees of freedom (DOF). This paper also proposes a controller design method of bilateral control systems in the heterogeneous environment. A one-dimensional master-slave haptic display system is taken as an example in this research. Firstly, haptic information, i.e. the position of each haptic device and the reaction force exerted on each haptic device, is transformed into environmental modes by means of mode transformation. Then the haptic information in the modal space is transmitted between master and slave haptic devices. The controller is designed so as to optimize mode-space transparency. Transparent bilateral control in the modal space is achieved even when the system connection changes, e.g. the capacity of communication network or the DOF of haptic devices changes. The proposed controller design method is validated by experimental results. © 2010 IEEE.

A bilateral control robot is one of the master-slave teleoperation robots. Consider two robots, a master robot is manipulated by human operators and a slave robot contacts remote environment. Decoupling of a force control and a position control in bilateral control is realized using the mode transformation i.e. a force controller in the common mode and a position controller in the differential mode. In conventional method, high transparency in a bilateral control is obtained when the inertia of the master and slave robots are equal. However, high transparency is not achieved when the inertia of the master and slave robots is different. Additionally, transparency goes down in the case of the bilateral control with scaling. Since the common mode and the differential mode interfere when the inertia and scaling of the master robot slave robots are different. In this paper, modal space disturbance observer (MSDOB) is proposed to solve these interferential problems. MSDOB is disturbance observer in the modal space and is implemented in each mode. MSDOB eliminates these interferences and modeling error in the modal space. In the results, decoupling of the force control and the position control is realized. Therefore, high transparency is achieved even if the inertia and the scaling of the master and slave robots are different. From the simulation and experimental results, the validity of the proposed method was confirmed. © 2010 IEEE.

In this paper, a bipedal locomotion planning based on virtual linear inverted pendulum mode (VLIPM) is proposed. In conventional methods, the desired center of gravity (COG) position and velocity are achieved by modifying the foot placement. In this research, the desired COG position and velocity are achieved while the desired foot placement is also realized. In the proposed method, the virtual modified foot placement and trajectory planning are calculated separately. VLIPM is applied to the calculation of the virtual modified foot placement. By using virtual supporting point (VSP), the difference between the virtual modified and desired foot placements is compensated. In the result, the desired foot placement is achieved as if the foot placement is in the virtual modified foot placement. Trajectory planning is applied to LIPM with VSP and 5-D polynomial. The boundary conditions of the polynomial are set to the desired COG position and velocity. In the result, the desired COG position and velocity are also obtained. Differences of the motion by different models are compensated by matching the boundary conditions of different models. By applying different models in the calculations of the foot placement and trajectory planning, the desired robot motion is realized. The walking stability of the proposed method is equivalent to that of the conventional method. The effectiveness of the proposed method is confirmed by a simulation and an experiment.

This paper describes a pushing motion for an unknown object by a humanoid robot. This method deals with an object whose parameters are not known. In order to push the unknown object, the robot motion must be decided according to the object. Therefore, the robot judges whether the unknown object is movable or not. When the robot judges the object is unmovable, the robot stops pushing. On the other hand, when the robot judges the object is movable, the robot continues pushing and walking. When the robot walks during a pushing motion, the influence of the pushing motion may destabilize a walking motion. Therefore, ZMP trajectory is modified by reaction force response before one step. Additionally, cycle time in double support phase is also modified by using sigmoid function. In the result, the heavier the object is, the more slowly the robot moves like a human. With these methods, the robot is able to push the unknown object during walking. Furthermore, even if parameters of the object change, this proposed method is available to continue pushing the object. © 2008 The Institute of Electrical Engineers of Japan.

This paper describes real-time gait planning for pushing motion of humanoid robots. This method deals with an object whose mass is not known. In order that a humanoid robot pushes an unknown object in both single support phase and double support phase, real-time gait planning for pushing the unknown object is proposed. Real-time gait planning consists of zero moment point (ZMP) modification and cycle time modification. ZMP modification is the method that modifies the influence of reaction force to ZMP. By cycle time modification, the period in double support phase is modified to avoid a robot tipping over. These modifications are calculated from reaction force on arms in every cycle. With these methods, trajectory planning for pushing an unknown object in both single support phase and double support phase is calculated. Even if parameters of an object and friction coefficient on the floor vary, the robot keeps on walking while pushing an object. The effectiveness of the proposed method is confirmed by a simulation and an experiment.

- Collision avoidance method of humanoid robot based on controlling extended orbital energy
This paper describes a collision avoidance method of a humanoid robot based on controlling the extended orbital energy. When a robot detects an obstacle using an arm tip, it should stop short of the obstacle to avoid crushing. However, modification of the ankle torque may destabilize a walking motion. We propose a method that the robot stops by utilizing an arm force. The COG trajectory is modified during walking by controlling the arm force. The robot stops within 2 steps after contact between the arm tip and the obstacle. During the first step, the COG velocity is reduced by changing the arm force. Here, the arm force is decided based on the extended orbital energy. During the second step, the robot stops just above the supporting point. In addition, the arm force becomes 0 smoothly when the robot stops. In the result, the robot is easily able to switch to the next action after stop.

- Real-time gait planning for pushing motion of humanoid robot
This paper describes real-time gait planning for pushing motion of a humanoid robot. We propose ZMP modification and cycle time modification. ZMP modification is the value which compensates the influence of virtual force to ZMP. Cycle time modification is that the period in double support phase is modified to avoid a robot tipping over. These modifications are calculated from information of reaction force on arms. In these methods, a robot walks while pushing an unknown object. Even if parameters of a object and friction coefficient on the floor vary, the robot keeps on walking while pushing. The effectiveness of the proposed method is confirmed by a simulation and an experiment.
