Simulation of spiral motion based on collision detection

This study starts from solving the position and velocity of the dragon head and the handles in front and behind the dragon body of the dragon dance team. The equations of motion are established. Considering the geometric relationship between each handle and the length of the board, solve for the position and velocity of the handles in front of the dragon's head. Recursively derive the parameter of motion at each point thereafter. In this paper, in order to solve the critical condition of non-collision between the benches of the dragon dance team. With the help of rotation matrix and graphical transformation, the complex collision problem is transformed into a simple problem of whether the points fall into the danger zone. It improves the performance success rate and spectacle of the bench dragon.
