— This paper proposes the application of an adaptive impedance control scheme to alleviate some of the problems associated with the presence of time delays in a haptic tele-operation system. Continuous on-line estimation of the remote environment's impedance is performed, and is then used as a local model for haptic display control. Lyapunov stability of(More)
— With the spread of low-cost haptic devices, haptic interfaces appear in many areas in the field of robotics. Recently, haptic devices have been used in the field of mobile robot teleoperation, where mobile robots operate in unknown and dangerous environments performing particular tasks. Haptic feedback is shown to improve operator perception of the(More)
