  • Robot system and robot control method
    Patent number: 10894320
    Abstract: A robot system includes a robot, a control circuit, a first wireless circuit, a second wireless circuit, and a teaching circuit. The first wireless circuit is connected to the control circuit. The teaching circuit is connected to the second wireless circuit to control the robot via the second wireless circuit, the first wireless circuit and the control circuit. The second wireless circuit is configured to transmit a control signal to the first wireless 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, and transmit an information signal to the first wireless 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.
