It's just a concept. Please criticize the ultrasonic induction to find the table tennis position, and then use the suction pump to suck it into the inner cavity and then transfer it to the top storage barrel through the internal threaded conveyor belt. The transparent storage barrel has a paddle (electric induction drives the motor to rotate to achieve the rotation effect under the paddle), which can transfer the ball to both sides to avoid crowding at the transmission terminal port.

Suck into the cavity and spit it out?

What is the principle of the concept?
