Abstract
A method for controlling a walking assistant apparatus includes: scanning a user so as to generate information associated with gait of the user; detecting a torque applied to a torque sensor; estimating a speed of the user based on the information; calculating a compliant motion speed, and a compliant rotational speed; and controlling the motion unit to move at the compliant motion speed and to turn at the compliant rotational speed. This disclosure provides an autonomous obstacle avoidance mechanism; by combining the obstacle avoidance mechanism and the compliance controls, the walking-assistance apparatus is able to help user prevent from collisions with obstacles when walking in an environment with obstacles.
