Problems solved by technology

[0003] In the technology of searching the working path, the offset search is mainly used now. Although the offset search has a careful offset calculation method and a point superposition method, there are also great disadvantages.
That is, the touch point needs to be taught in strict accordance with a specific direction, and the teaching steps are cumbersome
In addition, for the L-shaped work object, it is required to be vertical on both sides in the offset search method, which reduces the applicability of the search method

specific Embodiment

[0188] The following uses a welding robot as an example to explain the above-mentioned plane search method in detail:

[0189] This plane search method includes a teaching step, a search step and a calculation step; refer to Figure 5 , where the teaching part is operated by workers before the robot performs batch operations. The process of the teaching part is as follows:

[0190] Step 1: Control the teaching robot to move to the starting point where it can move in a straight line without being hindered and touch the two surfaces. Record this point as point 1 (x1, y1, z1);

[0191] Step 2: Move the teaching robot to the first plane and touch it, and record this touch point as point 2 (x2, y2, z2);

[0192] Step 3: Set the radius r of the circle centered at point 2 1 , the circle is perpendicular to the straight line connecting point 1 and point 2, so that moving from point 1 to any point on the circle can touch the first plane;

[0193] Step 4: Move the teaching robot to ...

Abstract

The invention discloses a robot path search method, system, device and storage medium, wherein the method includes: combining the starting coordinate point and the first preset coordinate point, controlling the robot to obtain n coordinate points on the first plane of the workpiece , obtain the first plane equation of the first plane according to the obtained coordinate points; combine the initial coordinate point and the second preset coordinate point, control the robot to obtain n coordinate points on the second plane of the workpiece, and obtain The second plane equation of the second plane; combine the first plane equation and the second plane equation to obtain the machining path of the robot. The present invention directly obtains the machining path of the robot by using two plane equations, avoids obtaining the offset of the workpiece in the offset search method, and then calculates the machining path based on the offset, which greatly simplifies the steps of robot teaching and searching, and provides It improves the working efficiency of the robot and can be widely used in the field of robot path planning.

Description

technical field [0001] The invention relates to the field of robot path planning, in particular to a robot path search method, system, device and storage medium. Background technique [0002] In the production and processing application of industrial robots, before batch processing of workpieces, the robot will teach the workpiece; when batch processing of workpieces, there are position offsets and errors between the processed workpiece and the position of the workpiece during teaching. In order to solve the above problems, the existing technical method is to confirm the actual working path by comparing the initial teaching point, searching and calculating the parallel and rotational offset of the working object. [0003] In the technology of searching the working path, the offset search is mainly used now. Although the offset search has a careful offset calculation method and a point-position superposition method, it also has great disadvantages. That is, the touch point n...
