Flight Trajectory Simulation of Robotic Throwing Shuttlecock

Abstract

The theme of the ABU Asia-Pacific Robot Contest in 2018 is to throw the shuttlecocks through the provided rings at height. The shuttlecock is an object made of cotton balls or filled with rice husks, symbolizing prosperity and happiness. For the design and control of robotic throwing mechanism, two aspects of research need to be carried out: selection of initial throwing parameters, aerodynamic behavior of shuttlecocks. Firstly, the influence of the initial throwing speed and the throwing angle on the throwing distance was studied through the kinematics simulation analysis, and the design of the throwing trajectory was further studied. In addition, the influence of air resistance on the flight trajectory was also studied. Finally, for the precise control parameters of the throwing mechanism, the rigid-flexible coupled multi-body dynamics simulation analysis was performed using ADAMS(Automatic Dynamic Analysis of Mechanical Systems) virtual prototype technology. The shuttlecocks throwing experiments conducted on the playing field showed that the design and simulation analysis of the throwing trajectory played a good guiding role in the design and development of the shuttlecocks throwing robot.
