A robot device, which autonomously performs actions, includes a moving unit that moves the robot device, and a target position acquiring unit that acquires position information of a target. A movement method judging unit receives an instruction for a movement from a user, and judges whether or not a destination can be designated by fixed position information. When it is judged that the destination can be designated by the fixed position information, control is performed by a position movement control unit. When it is judged that the destination cannot be designated by the fixed position information, control is performed by a target movement control unit, which acquires position information from the target position acquiring unit, to operate the moving unit.
