A leg type movable robot (1) has a seat (80) provided in its base body (3) so that the robot can sit on a chair. This reduces the occupied space and the space needed for storage or transport and improves transport safety. Further, since the robot can be fixed in its seated position, maintenance operation is facilitated. Further, the operating range is widened to make desk work possible. Further, the seat is positioned rearwardly of the center of gravity of the robot in its seated position. As a result, there is no possibility that the moment around the center of gravity, which acts on the robot as the latter is being seated, acts to rearwardly tilt the robot. Thus, the robot is allowed to hold a stabilized position before and after it is seated.
