Robot system and robot control method

A robot system comprising:

• a robot;
• a control circuit configured to control the robot;
• a first wireless communication circuit connected to the control circuit;
• a second wireless communication circuit configured to communicate with the first wireless communication circuit wirelessly;
• a teaching circuit connected to the second wireless communication circuit to control the robot via the second wireless communication circuit, the first wireless communication circuit and the control circuit;
• and
• the second wireless communication circuit configured to
• transmit a control signal to the first wireless communication circuit with a first wireless communication scheme using frequency hopping, the robot being configured to be driven or not to be driven according to the control signal,
• transmit an information signal to the first wireless communication circuit with a second wireless communication scheme in which a signal is transmitted in a case where a wireless resource is determined to be available, the information signal relating to driving of the robot, and
• perform short-range communication with the first wireless communication circuit such that, when the second wireless communication circuit transmits a short-range communication signal to the first wireless communication circuit via the short-range communication, a connection of the first wireless communication scheme and a connection of the second wireless communication scheme are established between the first wireless communication circuit and the second wireless communication circuit.
