Experimental Study on Bullet’s Exit Angle and Firing Accuracy of the Shooting Robot

The experiment was conducted in RoboMaster Laboratory of engineering training center. The automatic shooting robot designed by students could automatically recognize other static or moving robot targets through intelligent monocular vision system. The goal of the experiment was to enable the shooting robot to hit the target more accurately using a specific launching device. By analyzing the test results of massive data, a parabolic model with the correct exit angle of the bullet as the target variable was proposed. Through the construction of the parabolic model and the solution of the target variables, the preliminarily conclusion was that the parabolic motion could be used to fit the flight trajectory of golf balls. Therefore, the automatic robot could hit the targets at different distances and heights adaptively and accurately. Finally, the accuracy and effectiveness of the parabolic motion algorithm based on monocular vision of automatic robot were verified through the impact confrontation test and MATLAB simulation analysis. Meanwhile, students participating in the project developed a new understanding of machine vision through the exploration and research of each experimental module.
