A method for controlling the external motion path of a robot

Abstract

Disclosed in the invention is a robot external motion path control method. A robot controller receives external input motion path control signals; the signals are then processed by a signal processing module and a kinematics module in the controller into data capable of being received by an actuator; and curve motion of a robot along a complex path defined by a user is achieved. The method further comprises a software safety protection module, safety verification and data correction are carried out on the received control signals, and if the control signals cannot meet the requirement for normal running of the robot, then data correction is carried out on the control signals, so that running safety of the robot is guaranteed. With the method, the complex path curve of the robot is controlled, the robot controller has the beneficial effects of high accuracy, high reliability and high efficiency, the requirement for simple operation of a client is met, the manufacturing cost of the robot controller is low, and the method is effectively suitable for the robot engineering application environment.

Description

technical field [0001] The invention relates to a method for controlling the external motion path of a robot, belonging to the field of robot control. Background technique [0002] At present, the technology of industrial robots is developing very rapidly, and robots have become a standard equipment and are widely used in the industry.

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: in view of the limited types of motion instructions in robot control in the prior art, which can only realize the motion of simple and regular paths, and cannot effectively execute complex curved motions, the present invention provides a robot external motion path Control method, the robot controller receives the control signal of the external input motion path, and processes it into the data that the actuator can receive through the signal processing module and the kinematics module in the controller, so as to realize the movement of the robot along the user-defined complex path curve. Motion, not limited to simple regular paths in the robot controller
