Robot Collects Ping Pong Balls For You – Hackaday

If you’ve ever played ping pong, table tennis, or beer pong, you know that it’s a struggle to hang on to the balls. [MaximeMonsieur] has designed a robot to handle picking them up so you don’t have to.
The robot is specifically designed to pick up ultra-light ping pong balls. To that end, it has a large spinning paddle that simply wafts the balls into its collector basket at the rear. The robot gets around with a simple two-motor drive system, relying on skid-steering with a castor wheel at the rear. An Arduino Uno runs the show, and navigates the robot around with the aid of ultrasonic sensors to avoid crashing into walls.
Overall, the robot shows the benefits of designing for a specific purpose. Such a design would likely be far less successful with other types of heavier balls, but for ping pong balls, the spinning paddle collector works great. We can imagine the robot being put to good use between sets to pick up all the lost balls around a table tennis court.
We’ve seen other ball collecting robots before, too.

My aunt needs this. But then a heavier version, that can collect fallen walnuts from between grown grass.
Need to look into the bag-a-nut products, maybe a knock off of that would work.
Cool! Have heard of those. And thanks to this link, I know that those spikey seed pods are sweetgum.
I could use it for picking up juggling balls.
It’s like a Dust Buster™ for balls. Ball Buster? Deez Balls!
Looks like it can be used for a dog …
Do you mean ,”instead of a dog”? has posted blogs of machines that toss balls for dogs, with this canines can be removed from the equation.
No, to pick up dog poop. they’d sell millions.
