Researchers at ETH Zurich have demonstrated an amazing capability for small robots to self-assemble and take to the air as a multi-rotor helicopter. Maximilian Kriegleder and Raymond Oung worked with Professor Raffaello D’Andrea at his research lab to develop the small hexagonal pods that assemble into flying rafts. The true accomplishment of this research is that there is not one robot in control – each unit in itself decides what actions to take to keep the group in the air in what’s known as Distributed Flight Array.
