This is the Festo BionicBee: an autonomous robotic fly capable of autonomous flying in a warm. It weighs only 34 grams, measuring 22cm long, with a wingspan of 24 cm. It has a brushless motor, 3 servomotors, battery, gear unit, and circuit boards inside in its compact body.
This artificial bee flies with a stroke frequency of 15 to 20 hertz. The 3 servo motors change the geometry of the wing. For autonomous flying in a swarm, researcher used an indoor localization system with ultra-wideband technology.
