US Patent 11931891 Robot having flexible outer skin

A robot includes a trunk portion frame (functioning as a “base portion”), a head portion frame (functioning as a “first movable portion”) supported by the trunk portion frame, a flexible outer skin provided in such a way as to come into contact with the head portion frame and cover the trunk portion frame, and a pair of arm portions (functioning as a “second movable portion”), provided in contact with the outer skin, whose relative displacement with respect to the trunk portion frame changes in accompaniment to a displacement of the outer skin that accords with an operation of the head portion frame.
