Abstract

The invention is suitable for the technical field of robot motion control, and provides a robot joint pose monitoring method and device.According to the pose monitoring method, the motion state of a robot is monitored in real time in the real object debugging process of the robot; and whether the state of the robot is out of control or not is judged by comparing whether the difference value between the actual value and the theoretical value is larger than the preset monitoring value or not, if yes, the robot system is braked, and self-damage or external loss of the robot is avoided. The device disclosed by the invention also has the technical effects.

Description

technical field [0001] The invention belongs to the technical field of robot motion control, and in particular relates to a method and a device for monitoring robot joint poses. Background technique [0002] The motion control of a multi-joint robot is a very complex process, which involves many knowledges such as the establishment of the robot model, the robot forward kinematics, the robot inverse kinematics, the robot dynamics, the singular point, and the motor control. At the same time, the motion control of the robot is also affected by electrical wiring and mechanical design. During the operation of the robot, if there is a slight difference in the above-mentioned link, the control accuracy of the robot may be reduced, and the running trajectory may be deviated. It may even cause the robot's motion control to go out of control, collide with the surrounding environment and debugging personnel, and cause irreversible economic losses and personal damage. [0003] In the ...
