Abstract:
There is provided a robot device including: a head portion coupled to a trunk; four leg portions on a front left, a front right, a rear left, and a rear right coupled to the trunk; a first indirect portion that tilts the head portion left and right; and a second joint portion that rotates, with respect to the trunk, one of the leg portions on the rear left and the rear right to a front side, and the other to a rear side. It is possible to faithfully reproduce the movement of the four-legged animal by providing the first joint portion and the second joint portion.
