Path generation method and device

Abstract

The invention discloses a path generation method and device. The method comprises the following steps: a trajectory initial edge and a trajectory stop point are obtained; a trajectory is searched fromthe trajectory initial edge to determine multiple trajectory paths from the trajectory initial edge and the trajectory stop point; multiple trajectory edges needing to be passed through are inquiredin each trajectory path; trajectory tangential quantities between every two adjacent trajectory edges in the multiple trajectory paths are calculated to determine the trajectory path with the lowest change value of the trajectory tangential quantities; and the trajectory path is determined as a target trajectory path. The method solves the technical problem of shortening of the equipment service life due to sudden change of equipment joint changes caused by no consideration of turning angles of all the trajectory edges in the trajectory paths during generating of the trajectories by a robot inrelated technologies.

Description

technical field [0001] The present invention relates to the field of equipment path processing, in particular, to a path generation method and device. Background technique [0002] In related technologies, when a robot performs a series of tasks such as welding, grinding, polishing, and calibration according to the trajectory line, it often needs to find an optimal trajectory path in advance to perform corresponding work along the trajectory path. When generating a trajectory, the trajectory path with the shortest path is often selected, and the turning angle between each trajectory edge in the trajectory path is not considered. This often results in a larger turning angle when the robot works, and the joint angle of the robot works The rotation angle tends to change suddenly, which will cause serious damage to the robot for a long time, reducing the service life of the robot, and the damage to the joint angle will make the maintenance of the robot difficult and waste a lot ...
