Firstly, the path planning of soccer competition is introduced. And the dynamic path planning system of soccer robot competition is applied to picking robots. Based on the application characteristics of picking robots, the intelligent positioning and navigation system of picking robots is designed and simulated. The results show that the system can realize real-time positioning and navigation, and the path planning route is the best. There is no collision in the whole process, and the goal of successfully reaching the destination is achieved. The effectiveness and feasibility of the system are proved.
