A robot and work equipment are disposed near a work table including a work table-side controller and a process planning and designing controller capable of being operated by a user. The work table-side controller executes a work process in which the robot and the work equipment operate in conjunction, by receiving signals carrying identification and state monitoring information from a robot-side controller and the work equipment and then sending these signals to the process planning and designing controller, and by sending operation command signals to the robot-side controller and the work equipment in accordance with the aforementioned work process and then receiving operation status signals from the robot-side controller and the work equipment. Based on the signals carrying the identification and state monitoring information on the robot and the work equipment, the process planning and designing controller plans and designs the aforementioned work process.
