Abstract: Provided is a robot capable of appropriately adjusting a position and the like of a main body in view of executing a specified task involving an interaction with a target object. While the position and posture of the main body (10) are being controlled according to a second target path, the robot (1) moves from a first specified area to a second specified area and stands there. In this state, a second position deviation (=the deviation of the position of the main body from a second target path) and a second posture deviation (=the deviation of the posture of the main body from a second target posture) are determined. According to the determination result, the second target path is corrected so that the subsequent position deviation and the like may be smaller.
