Abstract: There is provided a mobile body including a mobile body main body, a movable unit that is attached to the mobile body main body and provides propulsive force to the mobile body main body, and a buffer attached to a surface of the mobile body main body. The buffer includes a deep layer material that covers the surface of the mobile body main body, and a surface layer material provided at a position more distant from the surface of the mobile body main body than the deep layer material. The surface layer material has a modulus of repulsion elasticity lower than the deep layer material.

Abstract: Provided is a robot device including a plurality of legs to perform a moving work. The robot device includes: a plurality of legs; and a body portion to which the legs are attached, the body portion having a bottom surface higher than a ground plane of the legs that are shortened to a maximum. The body portion includes a loading portion on which a load is placed in a space surrounded by the plurality of legs. Furthermore, an outer casing that covers the entire robot device including the plurality of legs is further provided. The outer casing includes an openable/closable lid or door on at least one of an upper surface, a front surface, a rear surface, a left side surface, or a right side surface.
