A legged mobile robot which permits improved follow-up of an actual floor reaction force to a desired floor reaction force and which can be stably controlled is provided. According to a robot 1 in accordance with the present invention, a deformation amount (mechanism deformation amount) of a compliance mechanism 42 that occurs due to a desired floor reaction force of a foot (ground contacting portion) 22 is determined, and the operation of a leg 2 is controlled such that the foot 22 lands onto a floor at a predetermined velocity in a vertical direction or in a direction perpendicular to the floor surface on the basis of a component of the mechanism deformation amount in the vertical direction or a component thereof in the direction perpendicular to the floor surface.
