[0002] Robotics competitions have been in schools for over a decade and have become a powerful means of cultivating innovative talents and promoting educational reform. Robotics competition projects are popular among students of all ages due to their fun, challenge, comprehensiveness, and competitiveness. Educational robots are robots used for science literacy education, engineering literacy education, and engineering skills education. Using robots as an educational platform is intuitive, interesting, and highly comprehensive. As soon as it was proposed, it received attention from the global education community and developed rapidly. In order to meet the needs of education, the four major components of educational robots—mechanical, control, sensor, and software—must all meet the requirements of openness and expansion, and be able to be closely integrated with teaching courses at all levels to achieve the teaching and training requirements of closely integrating theory and practice.

[0003] With the widespread development of robotics competitions, more and more schools and educational institutions are using robotics projects to cultivate students' hands-on and programming skills. However, most existing robotics competition equipment is finished products, lacking sufficient hands-on assembly and programming practice. Traditional robots are mostly limited to simple movements and basic task execution, lacking a certain level of fun and challenge, and failing to comprehensively improve students' overall abilities. Therefore, developing a robot that can be assembled and controlled by programming can not only cultivate students' creativity but also deepen their understanding of robot structure and programming principles, which has important educational significance.

[0004] To address the aforementioned technical challenges, a basketball shooting competition robot is proposed. Utility Model Content

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, this utility model embodiment provides a basketball shooting competition robot, which consists of a chassis 11, a motion system controlled by a handle, a ball picking system, and a control system.

[0028] The chassis 11 has integrally formed weight-reducing grooves 12 evenly distributed on one side, which reduces the overall weight while ensuring the stability of the chassis 11.

[0029] The motion system controlled by the handle includes a drive motor 15, a Mecanum wheel 16, and a signal receiver 14. The signal receiver 14 is mounted on one side of the chassis 11, and the four drive motors 15 are all mounted on the bottom of the chassis 11. The Mecanum wheel 16 is mounted on the output shaft of the drive motor 15. The drive motor 15 is controlled by the handle in conjunction with the signal receiver 14, and the Mecanum wheel 16 is used to achieve flexible movement in multiple directions, which is suitable for operation in confined spaces.

[0030] In one embodiment, the controller can be a PS2 controller for remote control, and the buttons and joysticks of the controller correspond to the various functions of the robot, including robot movement, ball picking and launching.

[0031] The ball-picking system includes a guide frame 21, a first guide plate 22, and a second guide plate 23. The guide frames 21 are symmetrically fixedly connected to one side of the chassis 11. The first guide plate 22 is fixedly connected to one side of both guide frames 21 and is used to guide the ball during pickup, directing it into the launch chamber formed by the two guide frames 21 and the chassis 11. The second guide plate 23 is fixedly connected to one side of the chassis 11 and is used to guide the ball's projection. One side of the second guide plate 23 is fixedly connected to the guide frame 21, and a rotary motor 35 is symmetrically mounted on one side of the second guide plate 23. A rotating drum 37 is mounted on the output shaft of the rotary motor 35. A first rotating shaft 27, a second rotating shaft 28, and a third rotating shaft 29 are rotatably connected to one side of each of the three shafts. A roller 25 is fitted on one side of each of the three shafts. Rubber bands 26 are fixedly connected to one side of each roller 25 at equal intervals. A servo motor 24 is installed on one side of the guide frame 21. The output shaft of the servo motor 24 is fixedly connected to the third rotating shaft 29. A driven wheel 31 is installed on one side of each of the first rotating shaft 27 and the second rotating shaft 28. A driving wheel 32 is installed on one side of each of the second rotating shaft 28 and the third rotating shaft 29. A first belt 33 is fitted on one side of each of the two driven wheels 31. A second belt 34 is fitted on one side of each of the two driving wheels 32.

[0032] In one embodiment, a guide groove is provided on one side of the second guide plate 23 to limit the projection direction of the ball and prevent projection deviation.

[0033] In one embodiment, in order to increase the friction between the rotating drum 37 and the ball contact surface, an anti-slip sleeve 36 is fitted on one side of the rotating drum 37. The anti-slip sleeve 36 is fixedly connected to the rotating drum 37, so that the rotating drum 37 can quickly complete the ball projection in conjunction with the rotating motor 35.

[0034] In one embodiment, to prevent the driven wheel 31 and the driving wheel 32 from rubbing against the chassis 11, the driven wheel 31 and the driving wheel 32 are of the same size, and the maximum radius of the driven wheel 31 is smaller than the maximum radius of the roller 25.

[0035] The control system is a self-designed main control board 13, which supports graphical programming such as Mixly, Mind+, etc., as well as C++ programming. The robot can be controlled and debugged through different programming languages, and students can learn the basic knowledge and practical skills of robot programming. The programming content includes writing programs to control the robot to move, pick up, and launch.

[0036] In operation, this invention is controlled via a PS2 controller and signal receiver 14. The left and right joysticks of the controller control the robot's forward, backward, and left / right rotation, respectively. The main control board 13 inside the robot is responsible for parsing the controller signals and, in conjunction with the drive motor 15, driving the Mecanum wheels 16 on the robot to perform corresponding movements. The main control board 13 can also control the ball-picking and launching structures according to different instructions. When picking up a ball, the robot moves to position the ball on one side of the robot's first guide plate 22, bringing the robot closer to the ball, and the servo motor 24, in conjunction with the third rotating shaft 29, drives the robot to move towards the ball. The drive wheel 32 rotates, and the drive wheel 32, together with the second belt 34, drives the second rotating shaft 28 to rotate. The second rotating shaft 28, together with the driven wheel 31 and the first belt 33, drives the first rotating shaft 27 to rotate, thereby causing the three rollers 25 to rotate. The rubber band 26 on one side of the roller 25 contacts the ball, and the ball is picked up from the ground and sent into the robot through friction. The rotary motor 35 is started to drive the rotating drum 37 to rotate. When the ball moves to the rotating drum 37, it contacts the anti-slip sleeve 36 on the outside of the rotating drum 37. The rotating drum 37 applies force to the ball, causing the ball to be thrown out through the guidance of the second guide plate 23.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
