The world of robots has lots of shapes. The more impressive is probably the human-like robots, because it is easy for us to compare them to a real human: we just need to watch our body. For animal-like robots, it is really different. However, one of the oldest dreams of the mankind is to fly. That is possible since the invention of Wright brothers, but aircrafts are not comparable to birds. Marcus Fischer and his team created a robot that flies like a bird and presented it at the TEDglobal conference in 2011.
