In order to solve the problems of large distance deviation and angle deviation of the blocking robot at different speeds,a method of obstacle avoidance and real-time tracking of the motion trajectory of the volleyball blocking robot is proposed to track the motion trajectory of the blocking robot in real time.Firstly,the mechanical structure of the blocking robot is analyzed,and the operation of the blocking robot is analyzed according to its motion characteristics;the sonar sensor is installed on the blocking robot to detect the sphere,and the motion planning of the volleyball blocking robot is completed according to the detection results;on this basis,the trajectory tracking model of the blocking robot is constructed,and the model is used to track the trajectory of the blocking robot in real time.The experimental results show that the proposed method can improve the tracking accuracy of the running trajectory,and the distance deviation and angle deviation under different speed motion states are small,which proves the effectiveness of the proposed method.
