Abstract

A robot control system and method for controlling a robot that performs working on a working path between a specified working start point and a working end point. The robot control system includes an interrupt request signal generating section for generating a signal for requesting change of the working path of the robot, an upper controller for generating an interrupt signal including a specified changed value for changing in real time the working path of the robot in accordance with the interrupt request signal generating section, and a robot controller for controlling in real time the operation of the robot in accordance with the interrupt signal from the upper controller. Thus, the motion of the robot that is working can be changed in real time.

Claims

1. A robot control system for controlling a robot that performs working on a working path between a specified working start point and a working end point, the robot control system comprising:

an interrupt request signal generating section for generating a signal for requesting change of the working path of the robot;

an upper controller for generating an interrupt signal including a specified changed value for changing in real time the working path of the robot in accordance with the interrupt request signal generating section; and

a robot controller for controlling in real time the operation of the robot in accordance with the interrupt signal from the upper controller.

2. The robot control system as claimed in claim 1, wherein the robot controller has a built-in program that includes a specified parameter for transmitting/receiving the interrupt signal from the upper controller.

3. The robot control system as claimed in claim 2, wherein the upper controller and the robot controller transmit/receive the interrupt signal by a parallel communication method.

4. The robot control system as claimed in claim 3, wherein the interrupt request signal generating section is at least one of a manipulation panel manipulated by a user, laser sensor, vision sensor, and vision camera.

5. The robot control system as claimed in claim 3, wherein the interrupt request signal generating section is at least one of a manipulation panel manipulated by a user, laser sensor, vision sensor, and vision camera.

6. The robot control system as claimed in claim 2, wherein the interrupt request signal generating section is at least one of a manipulation panel manipulated by a user, laser sensor, vision sensor, and vision camera.

7. The robot control system as claimed in claim 6, wherein the robot controller can change the working end point of the working path based on the changed value included in the interrupt signal by controlling in real time the operation of the robot in accordance with the interrupt signal.

8. A robot control method for a robot control system having a robot that performs working on a working path between a specified working start point and a working end point, an upper controller for receiving various kinds of signals from the outside and controlling as a whole the working of the robot based on the signals, and a robot controller for controlling the operation of the robot in accordance with a command signal from the upper controller, the method comprising the steps of:

inputting to the upper controller a signal for requesting change of the working path of the robot;

the upper controller generating an interrupt signal that includes a changed value of the working path of the robot and transmitting in real time the interrupt signal to the robot controller; and

controlling in real time the operation of the robot in accordance with the interrupt signal.

9. The robot control method as claimed in claim 8, wherein the step of transmitting in real time the interrupt signal to the robot controller transmits/receives the interrupt signal by a parallel communication method.

10. The robot control method as claimed in claim 9, wherein the signal for requesting the change of the working path of the robot is generated from at least one of a manipulation panel manipulated by a user, laser sensor, vision sensor, and vision camera.
