In this paper a new model-mediated teleoperation framework based on rate-control input is presented. The system facilitates force feedback teleoperation and is inherently robust to severe time delays yet still provides high level of rate/force tracking fidelity. Previously published methods on model-mediated teleoperation are here extended to accept rate commands and use the slave robot's programmed...
This paper presents an extension of the time-domain passivity control approach to a four-channel bilateral controller under the effects of time delays. Time-domain passivity control has been used successfully to stabilize teleoperation systems with position-force and position-position controllers; however, the performance with such control architectures is sub-optimal both with and without time delays...
