Bilateral teleoperation by sliding mode control design approach

Sliding mode control has been used extensively in robotics to cope with parameters uncertainty, model perturbations and system disturbance. Bilateral robotic teleoperators are often required to provide a haptic interaction in telerobotic applications in which human kinesthetic sense is stimulated locally by remote environment. The paper deals with bilateral control for a force-reflection master-slave telerobotic architecture. It involves a short overview of basic bilateral modes. Chattering-free SMC design procedure for force-reflecting master-slave teleoperator is presented. The proposed bilateral control scheme was experimentally validated for a 1DOF master-slave teleoperator.
