Abstract
A device for a robot is disclosed. In the device for a robot, a first signal is transmitted from a robot control device to the robot, a second signal is transmitted from the robot control device to the device for a robot, and a third signal is transmitted from the robot control device to the device for a robot, the third signal being transmitted from the robot control device in a case where there is a communication error between the robot control device and the device for a robot so that the device for a robot is restarted via a reset circuit.
Claims19
A device for a robot,
- wherein a first signal is transmitted from a robot control device to the robot, a second signal is transmitted from the robot control device to the device for a robot, and a third signal is transmitted from the robot control device to the device for a robot, the third signal is transmitted from the robot control device when a communication error between the robot control device and the device for a robot occurs so that the device for a robot is restarted via a reset circuit,
- wherein the device for a robot is restarted via the reset circuit when the device for a robot receives the third signal which is a low-level signal continuing for a first period, and
- the first period has a 9×n-bit length, and where n is a real number greater than 1.
A device fora robot,
- wherein a first signal is transmitted from a robot control device to the robot, a second signal is transmitted from the robot control device to the device for a robot, and a third signal is transmitted from the robot control device to the device for a robot, the third signal is transmitted from the robot control device when a communication error between the robot control device and the device for a robot occurs so that the device for a robot is restarted via a reset circuit, and
- wherein the robot control device transmits the third signal which is a low-level signal continuing for a period having a 9×n-bit length at a transmission speed of 1/n, and where n is a real number greater than 1.
A device fora robot,
- wherein a first signal is transmitted from a robot control device to the robot, a second signal is transmitted from the robot control device to the device for a robot, and a third signal is transmitted from the robot control device to the device for a robot, the third signal is transmitted from the robot control device when a communication error between the robot control device and the device for a robot occurs so that the device for a robot is restarted via a reset circuit, and
- wherein the robot control device consecutively transmits the second signal to the device for a robot a predetermined number of times and the robot control device transmits the third signal when receiving no response signal with respect to the second signal.
