This paper aims to develop a crutched walking frame with one-wheel driving system for the walking-impaired person as the aged. The walking frame is made up of four main parts : the steering and suspension system, the driving unit using the worm gear, the sensor and the controller. The walking frame can be controlled to keep the stable attitude by using the tilt sensor that measure the tilting of frame. The experimental results without control motion and with control motion for the downhill and uphill are presented in this study. Finally, a comparison between these results is presented to show the validity of system.
