This is a list of machines that can perform physical juggling patterns.

  • The first juggling machines were built by Claude Shannon. His most famous juggling machine was made from an Erector set in the 1970s. It had two cups on the ends of its arms, which were fixed relative to each other. It could bounce juggle 3 small steel balls on a tightly stretched drum by rocking the arms back and forth to catch and throw the balls with the cups.
  • In 1989 Stefan Schaal and Chris Atkeson made an improved version of Claude Shannon's machine that could bounce 5 balls.
  • The Buehgler robot, designed by Martin Bühler and built by Daniel Koditschek and Alfred Rizzi in 1989, juggles two ping pong balls in columns by bouncing them off of a rotating bar.
  • The Sarcoman Robot made by Sarcos Robotics in 1995, which is remotely controlled by a human operator, can juggle a 3 ball cascade using two cups at the ends of its arms. It can also do devil sticks, balance a pole, and bounce a ball on a paddle.
  • In 2001, Ernie Palarca built a machine that juggles 3 balls in a reverse cascade.
  • A robot made by students at the Czech Technical University in Prague can juggle up to 5 pool balls. It has two arms that can move vertically and horizontally and have cups at the ends that it uses to hold the balls. A high-speed camera is used to detect the movement of the balls and predict where the arms need to move to catch them. A spring-loaded third arm is used to add balls to the pattern while starting and when the machine drops.
  • A robot made by Paul Kulchenko can bounce 2 ping pong balls on a horizontal paddle. It tracks the movement of the balls using high-speed cameras and uses that information to calculate where to move the paddle.
  • A robot made by Takahiro Kizaki and Akio Namiki can juggle 2 balls in one hand, using two high-speed cameras to track the movement of the balls.
  • A humanoid robot made by Disney Research can juggle a shared 3 ball cascade with a human partner. It uses an external camera system to track the balls thrown to it, so it can predict where it will need to move its hand to catch them.
  • A robot made with 3D-printed parts by Nathan Peterson can juggle 7 marbles by rolling them on an inclined surface. It can also do siteswaps.
