Motion control of omni-directional walker for walking support

摘要

An omni-directional walker (ODW) has been developed which can support people with walking disabilities to perform indoor walking. During walking support, the walker can identify the user's directional intention according to the user's forearm pressures and support the user to go in the intended direction. In this paper, an adaptive control method is proposed to control the ODW's movement toward the direction in which the user intends to go. Simulation results show that the ODW can accurately follow the user's intention direction with the proposed control method.
