1. A moving device for moving a moving object while having the moving object loaded thereon, the moving device comprising:
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,
wherein, under a state of four-wheel ground contact in which both of the end-portion wheels that are rear wheels and both of the intermediate wheels that are front wheels are in contact with a ground, when the end-portion wheel is moved from a boarding area to a step of an escalator and/or when the end-portion wheel is moved from the step to a landing area of the escalator, a wheel speed of both of the end-portion wheels that are rear wheels is controlled by the control unit,
wherein the control unit is configured to acquire coordinate values obtained when the intermediate wheel is moved from the boarding area to the step or when the intermediate wheel is moved from the step to the landing area, and to control the wheel speed of the end-portion wheel when the end-portion wheel arrives at a position identified by the coordinate values.
