Nature inspires flying robot design

23 May 2014 Last updated at 00:23 BST

Scientists are copying from nature to design the next generation of drones - flying robots designed for everything from military surveillance to delivering goods to our doorsteps.

In a special issue of the journal Bioinspiration and Biomimetics, scientists in the US and Europe reveal drones with bird-like talons for grasping objects, and some that actively avoid obstacles using only visual sensors.

This could enable them to fly in built-up areas, as effectively as birds and insects.

UK-based aerial robotic expert Dr Mirko Kovac from Imperial College explained to BBC News how, with a greater understanding of the feats of navigation and control that flying animals are capable of, drones inspired by nature are set to become part of our everyday lives.
