Transitional track planning method applied by industrial robot

The invention discloses a transitional tracking planning method applied by an industrial robot, which can realize the transition between a joint space track and a cartesian space track, and the transition between two tracks of the cartesian space, the transitional track between different movement tracks are planned under the cartesian space, and has an intuitive shape; by adopting the algorithm that two parabolas are fused into one transitional curve, the smoothness of the track, speed and acceleration can be ensured, and the curve shape is controllable; the transitional track is formed by six independent curves, and the transition can be realized on the track with only posture change without position change; from the engineering application angle, the path velocity of transitional track boundary is restrained by utilizing the included angle between the tracks and the system allowable chord error, the boundary posture rotation speed is restrained by the similar mode, so that the large impact on a mechanical system caused by overhigh engagement speed can be prevented.
