In minimally invasive telesurgical systems, displaying the forces measured at the slave side is an important issue. Latency in communication lines limits the transmission of vivid tactile sensations and drives the system unstable. In this paper, we propose a new model-based approach for the bilateral control of a telesurgical robot using time-domain passivity control. This method consists of a virtual slave model implemented at the master side to estimate the force on the slave side. During the operation, the estimated force from the virtual slave is added to the actual measured force transmitted from the slave in order to maintain the passivity of the system. Both simulation and experimental results confirm the performance of this new controller.
