Abstract
A foot of a robot includes a lower plate, a first infrared transmitting and receiving unit and a circuit board electrically connected to the first infrared transmitting and receiving unit that are arranged on the lower plate. The first infrared transmitting and receiving unit is arranged in such a way that infrared light transmitted from and received by the first infrared transmitting and receiving unit travels in paths that are inclined with respect to the lower plate toward an area in front of the foot when the lower plate is substantially horizontal, so as to detect existence of a footing.
