Not to be outdone by their flying cousins, some less mobile bots are taking on the challenge of juggling. After the break you'll find a pair of vids, including one featuring a creation from the Czech Technical Institute in Prague that can launch five balls between its two "hands" with the aide of a high-speed tracking camera.
