Boffins in Prague have created a juggling robot which is capable of throwing and catching five balls moving at a time.
The team from Czech Technical University's Department of Control Engineering say the machine is an example of how motors can be used for precision tasks.
Dubbed 'Servo Juggler' it uses two mechanical vertical arms mounted on a motor and able to move horizontally to toss over a ball between each other on a parabolical trajectory.
A high-speed camera mounted at the front then detects the movement of individual balls and the system then calculated the ideal catching/throwing point. Sounds like a load of old balls to us.
