A robot 100P selects and executes its own motion. A robot 100Q receives a robot ID from the robot 100P and identifies the robot 100P, which is the transmission source, by the robot ID. The robot 100Q also receives an operation command from the robot 100P and executes a motion associated with the motion command. As a result, behavioral characteristics of the robot 100Q are influenced by the motion command of the robot 100P. The robot 100Q transmits said motion command to a separate robot 100R. A communication device that transmits and receives the robot ID or the like is built into a horn 112 of robots 100.
