[ Watch the Video: Bees Inspire Landing Technology For Robotic Plans ] Lee Rannals for redOrbit.com – Your Universe Online Honeybees are inspiring scientists at Australia’s Vision Centre to help build a robot aircraft. Bees are able to land anywhere with amazing precision and grace, and this skill could soon be included in future aircraft. Scientists found that honeybees are able to control their flight speed in time for a perfect touchdown without needing to know how fast they...

How Do Birds Avoid Crashes?

The secret of how birds zip flawlessly through narrow spaces without crashing into obstacles has been unlocked by Australian scientists. Their discovery could be used to design ℠bird-safe´ buildings and windmills, and improve the versatility of pilotless aircraft. Researchers at The Vision Centre have found that birds weave rapidly and safely through dense forests and narrow corridors by using their eyes to sense the speed of background image flow on both sides and adjust...

Honey bees undergo a sudden transition from speeding aircraft to hovering helicopter as they perform the delicate art of landing on a flower. Unlike the "Ëœcontrolled crash' of a fly landing, the bee lands with utmost delicacy after "Ëœreading' its airspeed visually, hovering above its landing ground and sensing it with vision, feelers and legs. Scientists worldwide have devoted decades to studying how honeybees navigate their way around the landscape but now a team from...

Landing is tricky: hit the ground too fast and you will crash and burn; too slow and you may stall and fall. Bees manage their approach by monitoring the speed of images moving across their eyes. By slowing so that the speed of the looming landing pad's image on the retina remains constant, bees manage to control their approach. But what happens in the final few moments before touch down? And how do bees adapt to landing on surfaces ranging from the horizontal to upside-down ceilings? Flies...
