Abstract
A legged moving robot has a plurality of movable legs for repeatedly touching and leaving a floor. A force sensor is mounted on each of the movable legs at a position spaced from a foot sole thereof toward a proximal end thereof, and detects at least a force and a moment based on a reactive force applied from the floor to the foot when the foot is landed on the floor. The foot is tilted along a ridge on the floor by actuators when the foot is landed on the ridge such as the edge of a stair. A position of the center of the reactive force applied from the floor to the foot is recognized on the basis of the force and the moment detected by the force sensor, in a plurality of tilted attitudes of the foot when the foot is tilted. A landed direction and/or a landed position of the foot with respect to the ridge is recognized on the basis of the position of the center of the reactive force recognized in the plurality of tilted attitudes of the foot.
