Description

Technical Field

[0001] This utility model relates to the field of competitive robot technology, and in particular to a flexible steering device for competitive robots. Background Technology

[0002] Tennis is not only an elegant, aristocratic sport, but also a sport that brings us joy, cultivates our character, and energizes us. More and more people are using their weekends to practice tennis on the court. In tennis training, the first thing we encounter is the tennis ball machine, which can help you train more conveniently and quickly. Currently, most tennis ball-serving robots have a fixed launch angle, which cannot be adjusted according to needs, resulting in generally limited training effectiveness.

[0003] A search revealed that application number CN202421959312.0 discloses a tennis serving robot that solves the aforementioned problems. This device includes a main shell and a base. A rotating shaft is fixedly installed at the bottom of the main shell, and the other end of the shaft is rotatably connected to the top of the base. A motor is fixedly installed at the top of the base, and the output of the motor drives a first gear. A second gear is fixedly installed on the rotating shaft, and the first and second gears mesh for transmission. The main shell has an internal partition that divides its interior into a striking chamber and a high-pressure gas chamber. The partition has a connecting port that connects the striking chamber and the high-pressure gas chamber, and a first solenoid valve is fixedly installed on the connecting port. The top of the main shell has a ball inlet that connects to the striking chamber. A baffle mechanism is provided at the connection between the ball inlet and the striking chamber. The main shell also has a striking outlet that connects to the striking chamber. However, this device uses a fixed bottom structure, which only allows for adjustment of the serving angle, while the part in contact with the ground cannot move and lacks angle adjustment functionality. Therefore, we propose a flexible steering device for competitive robots. Utility Model Content

The drive motor 3 is fixedly connected to the bottom of the base 1, and its output end is connected to the drive pulley 20 through the drive rod 18. The drive pulley 20 drives the drive pulley 17 to rotate through the drive belt 19. The drive rod 5 then transmits the power to the sliding wheel 4, causing it to turn. This structure enables the device to move, solving the problem of the original equipment not being able to walk autonomously, thereby enhancing the robot's mobility in the competition field. The sliding wheel 4 is rotatably connected to the base 1, and with the anti-detachment ring 24 design, it prevents the drive rod from falling off, improving operational stability and safety, and facilitating maintenance. In addition, A directional transmission structure is provided on one side of the sliding wheel 10 for precise adjustment of the serving direction. This structure is driven by the adjustment motor 21. The output end of the adjustment motor 21 is connected to the directional lever 12 and drives the directional pulley 13 to rotate.
