With the development of artificial intelligence technology, industrial robots are widely used in work scenarios such as gripping and handling. However, due to the complex inverse kinematics solution and the existence of multiple solutions for poses, the robot has poor robustness and its industrial application range is limited. To
simplify the solving process of inverse kinematics of industrial robot and realize the accurate control of robot pose in complex obstacle scene, quaternion was used to solve the robot pose, and an improved particle swarm optimization algorithm (F-PSO) was proposed combined with obstacle avoidance module in this paper. Through the comparative experimental analysis with the simulated annealing algorithm (SA) and the genetic algorithm (GA) under different target poses, it was proved that the F-PSO algorithm performed better, and the convergence accuracy was more than
36.41% higher than that of the traditional algorithm. The F-PSO algorithm was more than 83.82% faster than the traditional algorithm. The experimental results showed that the F-PSO algorithm proposed in this paper can not only precisely control the pose of the robot, but also effectively improve the work efficiency and realize the optimization of the robot gripping process in the complex obstacle scene.
