Abstract
A moving device includes: two leg portions each including an end-portion wheel and an intermediate wheel; a placement portion supported by the two leg portions; and a control unit configured to control the two leg portions. The moving device is configured such that, under a state of four-wheel ground contact in which the end-portion wheel and the intermediate wheel are in contact with the ground, when the end-portion wheel is moved from the boarding area to the step of the escalator and/or when the end-portion wheel is moved from the step to the landing area of the escalator, a wheel speed of the end-portion wheel is controlled by the control unit.
