Juggling robot facts for kids

A juggling robot is a robot designed to be able to successfully carry out bounce or toss juggling. Robots capable of juggling are designed and built both to increase and test understanding and theories of human movement, juggling, and robotics. Juggling robots may include sensors to guide arm/hand movement or may rely on physical methods such as tracks or funnels to guide prop movement. Since true juggling requires more props than hands, many robots described as capable of juggling are not.

Bounce juggling

A toss juggling robot that can do more than a two ball column has only recently been built |publisher=IEEE Press |volume=3 |location=New York |pages=913–18 |doi= 10.1109/robot.1993.292260|isbn=978-0-8186-3450-5 }}</ref> Christopher G. Atkeson and Stefan K. Schaal of the Georgia Institute of Technology built a similar 5-ball bounce juggling robot. Decorated as and named W. C. Fields, Shannon's machine used grooved cups/tracks instead of sensors or feedback. Shannon also devised a juggling theorem.

In 1989 Martin Bühler and Daniel E. Koditschek produced a juggler with one rotating bar, moving one way then the other, that bounces two-props in a fountain of indefinite length.

Toss juggling

Sakaguchi et al. (1991) and Miyazaki (1993) produced a one-armed two-ball fountain juggler with a funnel-shaped hand. Kizaki and Namiki (2012) developed a fingered robot that does the same.

By 2011 students at the Department of Control Engineering at Prague's Czech Technical University built a 5-ball cascade juggling robot whose arms have both vertical and horizontal motion, whose hands are ring-shaped, and which contains a basket that provides the initial throws and relaunches any failed catches.

Disney Research is developing a robot capable of pass juggling with the goal of being able to provide more physical interaction between visitors and mechanized characters.

Contact juggling

Contact juggling appears to be less common among robots, as it is with people. However, in 2010 undergraduates at Northwestern University developed a robot capable of rolling a grooved disk from the center, over the edge, and to the center of the other side of a figure-eight shaped track capable of rotation.
