A walking rehabilitation robot system is provided, which can be worn by a user. The walking rehabilitation robot system includes two robot feet, any robot foot of the sound leg will generate a plurality of motion detection signals by first move so that another robot foot learns to move. A control device is electrically connected to each robot foot and receives the motion detection signals transmitted by the robot foot of first move. The control device calculates a first movement track by using the motion detection signals, and then calculates the required motor torque to generate a second movement track according to the first movement track. The control device controls the movement of the other robot foot based on the second movement track. The present invention is mainly designed for a user with a half body paralysis or an inconvenient mobility. The user uses a normal movement of sound half body so that the other robot foot can move the inconveniently moved part immediately.本發明提供一種行走復健機器人系統,可以供使用者穿戴。行走復健機器人系統包含二機器足,任一機器足先藉由使用者移動產生複數移動偵測訊號,以使另一機器足學習移動,一控制裝置電性連接每一機器足,控制裝置接收先移動的機器足所傳輸之移動偵測訊號,以計算出第一移動軌跡,並根據第一移動軌跡及移動偵測訊號計算出另一機器足之各軸馬達力矩,以控制機器足產生與第一移動軌跡對稱之第二移動軌跡。本發明主要是針對半側身癱瘓或行動不便之使用者所設計,使用者利用一半側身正常的移動,以使另一隻機器足即時帶動復健的部位移動。
