Abstract
A robot includes a gear device. The gear device includes an internal gear including internal teeth and an external gear including external teeth, which partially mesh with the internal gear, and having flexibility, the external gear relatively rotating around a rotation axis with respect to the internal gear, and a wave motion generator configured to come into contact with an inner circumferential surface of the external gear and move a meshing position of the internal gear and the external gear in a circumferential direction around the rotation axis. The gear device includes a wall section disposed at an end portion of tooth width of the internal gear and coupled to two dedenda adjacent to each other in the circumferential direction of the internal gear and a tooth bottom present between the two dedenda.
