Tiny Rescuers

News

Researchers from Purdue University, USA have created a series of flying robots inspired by hummingbirds, the world’s smallest birds. Each hummingbird robot has flexible wings made out of carbon-fibre with laser cut membranes, 3D bodies and two motors that can control each wing independently. The robots are so small that they can reach places where drones cannot go. They can move around on their own just like a normal hummingbird and their flexible flapping wings will enable them to perform new tricks. For example, they will be able to sense an object just by touching surfaces, even if they cannot see it. These robots will also map the areas they fly over and send information back to their controllers. The robotic hummingbirds will assist in search and rescue missions and also enable biologists to study real hummingbirds in their natural habitat.
