[0020] Example: Refer to Figure 1-2 A tennis serving competition robot as shown, which includes a main housing 1 and a base 11. The bottom end of the main housing 1 is fixedly installed with a rotating shaft 14, and the other end of the rotating shaft 14 is rotatably connected to the top end of the base 11. The top end of the base 11 is fixedly installed with a motor 12, the output end of the motor 12 is drivingly connected with a first gear 13, the rotating shaft 14 is fixedly installed with a second gear 15, and the first gear 13 and the second gear 15 are meshed and driven. A partition 2 is arranged inside the main housing 1, and the partition 2 divides the inner cavity of the main housing 1 into a hitting cavity 3 and a high-pressure gas cavity 4. A communication port 5 for communicating the hitting cavity 3 and the high-pressure gas cavity 4 is arranged on the partition 2, and a first solenoid valve 6 is fixedly installed on the communication port 5. The top end of the main housing 1 is provided with a goal inlet 7, and the goal inlet 7 is communicated with the hitting cavity 3. A baffle mechanism 8 is arranged at the communication part of the goal inlet 7 and the hitting cavity 3. A hitting outlet 17 is arranged on the main housing 1, and the hitting outlet 17 is communicated with the hitting cavity 3. An angle sensor 16 is fixedly installed on the outer side wall of the main housing 1. By driving the first gear to rotate by the motor to drive the second gear to drive the rotating shaft to rotate, the rotating shaft drives the main housing to adjust the orientation of the hitting outlet, so as to realize multi-angle hitting. The hitting angle can be detected by the angle sensor, which is very convenient.

[0021] With the above structure: a high-pressure air pipe 9 is fixedly installed at the rear end of the main housing 1. The high-pressure air pipe 9 communicates with the high-pressure gas chamber 4. A second solenoid valve 10 is fixedly installed on the high-pressure air pipe 9. When hitting the ball in this new type, the high-pressure air pipe injects high-pressure gas into the high-pressure gas chamber, and then the first solenoid valve is opened so that the high-pressure gas enters the hitting chamber. Under the push of the high-pressure gas, the ball falling from the goal inlet is hit out from the hitting outlet.
