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 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...
This paper presents a technique for a robust tracking of the target object by integration of the vision-based disturbance observer with bilateral haptic system. As for the motion navigation task, the bilateral control of master-slave system is combined with the vision-based force compliance controller. The disturbance of the modelling error that occurs in the integration of the system will be compensated...
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...
This paper proposes an evaluation index for the analysis of the motion complexity in parallel multi-degrees-of-freedom (MDOF) haptic system. Firstly, the modal decomposition based on discrete Fourier series expansion (DFS) is described. Modal information expresses a motion element that corresponds to a specific physical action. The modal information can be defined by the Fourier coefficients. This...
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...
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...
