Abstract
We have developed a gait simulator aimed at free walking. Comparing with a popular treadmill this gait simulator provides more freedom, that is, this simulator can reproduce a straight walking, a turn, and a going up and down the stairs. This gait simulator has two foot plates. These plates are moved by three arms and follow the foot during swing phase, and this plate pulls back the foot dring stance phase. The fastest walking speed of this gait simulator reaches to 3km/h in a straight walking.
