Research on robot trajectory planning algorithm with optimal acceleration

In order to solve the problem of overrun in the process of robot debugging, a control method with optimal acceleration is proposed based on T type velocity curve under motion constraint. The dynamics performance of the palletizing robot is analyzed by using Lagrange method and the realization process of robot trajectory planning algorithm is discussed. This algorithm makes full use of the driving performance of the driving joint on the basis of smooth and stable movements. Compared with the traditional velocity curves, the control effect of the robot is significantly improved both in the single axis mode and the axis group mode.
