This unusual robot called the Aquajelly is based on on jellyfish. Created by the company Festo, the idea is to use several of these at once as they can communicate on the surface using the Zigbee short range radio protocol.

See them in action in this video.

Festo has outdone itself and also created the Airjelly Robot. This robot uses a helium balloon and steers by shifting it’s weight.
