Abstract
Assistive walker is expected to have not only supporting function of user's upper part body, but also steering function performed by manual control when user's waist is not good to be twisted. For this purpose, we investigate a walker having a maneuvable function to control direction of walking. The principal idea is to prepare mechanical connection to change angular direction of wheels since a user can move a certain knob to find its optimal position. Steered angles of the walker are collected in the experiment depending on the angular direction. Finally, we show that the angular control at the back is good for delicate steering.
