Trajectory Planning of Rotor Welding Manipulator Based on an Improved Particle Swarm Optimization Algorithm
Bibliographic record
Abstract
The rotor is the main core component of the powder separator, and the processing quality of the rotor directly affects the working efficiency of the separator and the operation safety of the separator, for the problems of unprotected welding quality of the rotor of the separator and high labor intensity of manual labor, for the problem of time-optimal trajectory planning of the welding robot, the welding robotic arm as the object of the study, using the D-H method of modeling and forward and inverse kinematics analysis. An improved particle swarm algorithm is proposed to optimize the trajectory of a spin-welding robot arm due to the inefficiency of traditional robot trajectory planning and unstable operation. The method effectively combines the 3-5-3 polynomial interpolation function with the improved algorithm using time as the fitness function. By comparing the traditional particle swarm algorithm, it is shown that the improved algorithm can be better applied to the time-optimal trajectory planning of the welding robot arm.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
