Method and system for automatic robot teaching using vision and laser range finder

Abstract

The invention discloses a method and a system for realizing automatic demonstration of a robot by using visual and laser distance measurers. The method is characterized by comprising the steps of: obtaining original point position design information of one target demonstration point, and driving the robot to move above the point position; triggering the laser distance measurer to measure the distance, calculating a displacement value of the robot on a Z axle, and shifting an industrial camera on the robot according to the displacement value to enable a Z axle distance from the original point position of the target demonstration point to be the same with a fixed focal distance preset by the industrial camera; triggering the industrial camera to shoot, processing and identifying shot imagesto judge if an actual target demonstration point is shot, identifying real position information of the target demonstration point to store in the robot or a robot control unit if the actual target demonstration point is shot, and otherwise, setting multiple calibration shooting points to renewedly shoot and identify with a point corresponding to the original point position design information as the center. The method realizes full automation of the whole precise demonstration process.

Description

technical field [0001] The invention relates to the field of industrial automation, in particular to a robot teaching method. Background technique [0002] With the increase of labor costs and the development of science and technology, robots (especially industrial robots) are more and more widely used in the field of industrial automation. Before the use of robots, it is necessary to accurately teach the target points that the robots need to reach. So that the robot can accurately complete the required actions. [0003] The traditional teaching method is to use the teaching pendant of the robot to operate the robot to move to the target point, and then slightly move the tool to coincide with the target point. The whole process requires high skills of the robot operator and takes a long time; the teaching process is a Complicated processes, many of which are repetitive labor, manual teaching is doomed to fail to achieve a high degree of consistency; at the same time, in som...

[0003] The traditional teaching method is to use the teaching pendant of the robot to operate the robot to move to the target point, and then slightly move the tool to coincide with the target point. The whole process requires high skills of the robot operator and takes a long time; the teaching process is a Complicated processes, many of which are repetitive labor, manual teaching is doomed to fail to achieve a high degree of consistency; at the same time, in some equipment with more complex designs, humans and robots need to work in the same space, and operators will be harassed when they make mistakes. life safety is also affected to a certain extent
