Compared to existing technology, Net-Genius AI presents and offers remarkable beneficial effects with its innovation of an additional machine vision module supported by mathematical model and highly functional friction wheel.

The invention uses a camera to capture the user’s position information, allowing real-time interaction between the serving machine and the user. The steering servo motor, fixedly connected to the friction wheel chamber, is activated to rotate the friction wheel chamber, enabling the serving machine to serve in different directions.

The friction wheel motor is activated, causing the friction wheel coupler, fixedly connected to the lower part of the friction wheel, to rotate. As the friction wheel rotates under the influence of the friction wheel coupler, tennis balls enter the friction wheel chamber from the tennis ball chamber via the tennis ball rotating wheel and slide. The tennis balls are squeezed between the two friction wheels, propelling them out. Additionally, the pitch servo motor, mounted at the rear of the friction wheel chamber, can be used to adjust the serving angle, allowing the serving machine to produce more parabolic serves.
