A Canadian-built helicopter that is powered by a human riding a bicycle has become the first winner of a decades-old $250,000 engineering prize, the US awarder said Friday.
Terradynamics: Technique could help designers predict how legged robots will move on granular surfaces (w/ video)
Using a combination of theory and experiment, researchers have developed a new approach for understanding and predicting how small legged robots – and potentially also animals – move on and interact with complex granular ...
(AP) -- An ultralight, gas-powered car that can get 102 miles per gallon is among the winners of the $10 million Automotive X Prize, a contest to develop highly efficient, production-ready vehicles.
Tiny flying machines can be used for everything from indoor surveillance to exploring collapsed buildings, but simply making smaller versions of planes and helicopters doesn't work very well. Instead, researchers at North ...
New research shows some bees brace themselves against wind and turbulence by extending their sturdy hind legs while flying. But this approach comes at a steep cost, increasing aerodynamic drag and the power required for flight ...
(PhysOrg.com) -- Brute force rather than aerodynamic efficiency is the key to bumblebee flight, Oxford University scientists have discovered.
Australian bats developed a high-speed flying technology some 50 million years before aircraft engineers, according to Department of Parks and Wildlife zoologist Norm McKenzie.
Many owl species have developed specialized plumage to effectively eliminate the aerodynamic noise from their wings – allowing them to hunt and capture their prey in silence.
A study into the aerodynamic performance of feathered dinosaurs, by scientists from the University of Southampton, has provided new insight into the evolution of bird flight.
