Abstract
Disclosed herein is a mover including a plurality of wheels, a body, and a friction braking mechanism. The body has a bottom surface. The body is supported by the plurality of wheels with the bottom surface facing a traveling surface, and travels on the traveling surface by turning the plurality of wheels. The friction braking mechanism applies a brake on the body with at least a portion of the bottom surface or at least a portion of a movable body brought into contact with the traveling surface by switching, while the body is traveling, a state of the movable body from a first state into a second state. The second state is a state where the movable body protrudes from the bottom surface to a different height from in the first state.
