Abstract: A robot is autonomously moved locally by a move mechanism. In the robot, a check work memory stores a plurality of check works and check place to execute each check work in case of a user's departure to a remote location. A check work plan unit selects check works to be executed from the check work memory and generates an execution order of selected check works. A control unit controls the move mechanism to move the robot to a check place to execute a selected check work according to the execution order. A work result record unit records an execution result of each of the selected check works. A presentation unit presents the execution result to the user.
