Acerca de

A bilateral teleoperation system comprises a network of two manipulators, with the primary objective of achieving position synchronization between them. This paper proposes a novel continuous-time finite-time (FT) controller to solve the problem of bilateral teleoperation for a class of fully-actuated Euler-Lagrange (EL) systems in joint space. For this, the control law is designed to ensure global asymptotic stability (GAS) and then, finite-time stability (FTS) through a homogeneous ap- proximation of negative degree. To handle the external forces that arise from environmental interactions, it is assumed that these forces define passive velocity-to-force maps, enabling the proof of bounded position errors and velocities. The resulting controller is an easy-to-implement proportional plus damping injection (P+d) scheme with a gravity cancellation term. Experimental results with a teleoperation system composed of two robotic manipulators with six Degrees-of-Freedom (DoF) are presented to validate the performance of the proposed scheme.
