摘要:
A walking assist device having a safety mechanism that mitigates an impact upon falling is provided. A walking assist device has an upper and lower leg links, a motor, and a controller. The controller controls the motor to apply torque to the lower leg link. The walking assist device also has a one-way damper which generates a resisting force against rotation of the lower leg link in the knee bending direction, and does not generate a resisting force against rotation of the lower leg link in the knee straightening direction. The controller engages the one-way damper while controlling the motor to apply torque to the lower leg link in the knee straightening direction, and disengages the one-way damper while controlling the motor to apply torque to the lower leg link in the knee bending direction.
