After the bionic kangaroo, the robot penguin and the mechanical seagull, Festo - the German company specialized in automation - added another creature to the family: the bionic ant. These robotic insects are learning to work together, like real ants do. Maybe in the future they could clean up our offices or work in factories.
They are provided with antennae that have a very specific purpose: when they touch an electric rail the ants will charge themselves. They have cameras in their eyes and circuits and electric conduits running all over their bodies. Their size is equal to the dimension of a human hand.
Festo has designed a dozen of these ants and here you can see what they are already capable of.
