This article investigates virtual reality (VR)-based teleoperation with robustness against modeling errors. VR technology is an effective way to overcome the large time delay during space robot teleoperation. However, it depends highly on the accuracy of model. Model errors between the virtual and real environment exist inevitably. The existing way to deal with the problem is by means of either model matching or robot compliance control. As distinct from the existing methods, this article tries to combine m...
This article provides a flexible-joint-manipulator,which incorporates with three means to make its mechanical arm come into compliant contact with the objects with a force kept within an acceptable range. At first,the Cartesian impedance control law is introduced on the basis of virtual decomposition to realize the compliance control. Then,adaptive dynamic joint compensators on all joints are used to achieve more precise control. Finally,a Cartesian force-feedback path generation is developed for collision ...
