A fan of kinetic projects, [Jimmy Demello] threw together a pretty cool robot that can bounce a ball back and forth between its hand(s).
Made from scraps around the house, it consists of some wood, a piece of a fishing pole, chop sticks, a single servo motor, and of course an Arduino Uno. His original plan was to make [Claude Shannon]’s juggling robot, but this is as far as he’s gotten — so far anyway.
It bounces a 2cm ball-bearing twice before catching it and passing it back again. He thinks it would be an awesome project to scale up and use basketballs, and we’d have to agree.
And for more robotic fun, [Jimmy’s] also made an automatically actuated Newton’s Cradle!
For a more sophisticated juggling robot, you’ve gotta check this one designed by the Department of Control Engineering at the Czech Technical Institute in Prague — it’s capable of juggling five balls at once!
