Telerehabilitation Robot System with Haptic Feedback by Means of Brake and Deadband Control Towards Home Medical Welfare Support

Abstract

In this paper, a master-slave robot system involving haptic feedback and teleoperation for rehabilitation is presented. A teleoperation mechanism capable of force feedback by means of brake is proposed. The stability of the teleoperation system with haptic feedback via a time-delay communication environment is mathematically proved. Moreover, in order to reduce the packet transfer rate for data transmission, a deadband control approach is used. A new data reconstruction algorithm is proposed to improve the system's performance while maintaining the system's stability. This system allows passive assisted movement utilizing teleoperation for the rehabilitation of upper limb function.
