How does this table robot machine work?

About the arm movements, are these controlled by motors?

Yep, servo-motors by the look of it.

Servo-motors. Now I see. Thank you for your answer.

Careful how you read that suggestion….

I think @SteveThackery’s right, but a lot of punters on here don’t recognise the difference between a servo ‘motor’ and a ‘servo’… (a closed-loop control system)

Read around if you’re interested.

Thanks for the advice.
I read a wikipedia article on that.

Yeah, so it will use fairly powerful electric motors (for rapid acceleration/deceleration of the parts) with positional feedback. Widely used in robotics, as well as things like printers, computer-controlled manufacturing equipment, etc.

Thank you for your help, dsmts. That document is exactly what I needed to know.
I'll do a research on whether I can create a copycat of this machine with arduino.

A table tennis robot is a mechanism that can shoot table tennis balls in a controlled manner from one end of a table tennis table to the other.
You'll be able to select the kind of shots and spins you'd like to practice with (topspin, backspin, side-spin, etc.).
The frequency and speed with which the balls are shot may also be changed.
