Robotic Jelly Fish

A company in Germany called Festo has created two different types of robotic jelly fish: the AquaJelly and the AirJelly

AquaJelly (c) Festo

The AquaJelly uses an electric drive and as the programmed intelligence to emulate swarming behavior.  It has a translucent, water tight body and eight tentacles, which are used to move through the water.  It has a control board that uses eight white and eight blue LEDs, along with sensors, to talk to other AquaJellies. They can locate each other position to avoid colliding with each other.  They will also move to the charging station to get my power on their own.

The AirJelly is like a gaint flying jelly fish.  It has eight tentacles to produce a peristalic forward motion like a real jelly fish.  Movement through three-dimensional space is done with tentacles and weight displacement.  There is a pendulum on two actuators in the X and Y directions.  When the pendulum displaces the AirJelly’s center of mass, it moves in that direcion.  Unlike the AquaJelly, the AirJelly is remote controlled.
