Researchers at Chiba University, Japan, have developed a flying robot that flap its wings 30 times a second, just like a real humming bird.
Hiroshi Ryu, one of the researchers at the University, said the humming bird robot is equipped with a micro motor and four wings, which enable it to freely in mid-air with rapid wing movements. The 2.6gm robot is controlled with an infrared sensor and can turn up, down, right or left. Developed at a cost of $2.1 million, it could be used to rescue people trapped in destroyed buildings, search for criminals or even probe in mars. The researchers also plans to equip the robot with a mini camera by march 2011.
