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.

First claim

What is claimed is:

1. 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.

2. The device for a robot according to claim 1 ,
wherein the second signal is a signal other than a command signal for restarting the device for a robot, which is one of command signals to the device for a robot.

3. The device for a robot according to claim 1 ,
wherein the robot control device transmits the third signal to the device for a robot at a transmission speed of 1/n.

4. The device for a robot according to claim 1 ,
wherein the robot control device and the device for a robot communicate with each other through serial communication.

5. The device for a robot according to claim 1 ,
wherein the robot control device and the device for a robot are connected to each other via any of RS-422, RS-232C, and RS-485.

6. The device for a robot according to claim 1 ,
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.

7. The device for a robot according to claim 1 ,
wherein the device for a robot is a force sensor.

8. A robot control device which controls the robot provided with the device for a robot according to claim 1 .

9. A robot control device which controls the robot provided with the device for a robot according to claim 2 .

10. A robot control device which controls the robot provided with the device for a robot according to claim 5 .

11. A robot control device which controls the robot provided with the device for a robot according to claim 3 .

12. A robot control device which controls the robot provided with the device for a robot according to claim 4 .

13. A robot system comprising:
the robot provided with the device for a robot according to claim 1 ; and
a robot control device that controls the robot.

14. A robot system comprising:
the robot provided with the device for a robot according to claim 2 ; and
a robot control device that controls the robot.

15. A robot system comprising:
the robot provided with the device for a robot according to claim 4 ; and
a robot control device that controls the robot.

16. A robot system comprising:
the robot provided with the device for a robot according to claim 5 ; and
a robot control device that controls the robot.

17. A robot system comprising:
the robot provided with the device for a robot according to claim 3 ; and
a robot control device that controls the robot.

18. 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.

19. 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.
