Abstract
A rehabilitation and training apparatus is built based on the empirical law by introducing physical therapists'"'"' experiences into the apparatus to simulate therapy with hands in the course of rehabilitation. The apparatus includes a multi-axis robotic arm having first to eighth arm segments, and a high-precision control system for controlling movements of the multi-axis robotic arm. The control system provides an active, a passive and an auxiliary mode; receives and computes information about a patient'"'"'s movements and muscle force detected by potentiometers and force sensors provided in the multi-axis robotic arm; and accordingly, drives actuators to apply an aiding force or a resisting force to assist the patient in completing rehabilitation exercises. The apparatus also includes a humanized operating interface, via which a doctor or a physical therapist may obtain related rehabilitation data for assessment and adjustment of rehabilitation therapeutic courses. A method of controlling the apparatus is introduced.
