Researchers from the Biomimetics-Innovation-Centre in Germany have been inspired by birds to produce a new versatile design of Micro air vehicle (MAV) that combines flapping wings, which allow it to fly at slow speeds and hover, with the ability to glide, ensuring good quality images from any on-board camera.
"In birds, the combination of demanding tasks like take-off, travelling long distances, manoeuvring in confined areas and landing is daily practice," explains PhD researcher Mr. William Thielicke, who is presenting this work at the Society for Experimental Biology Annual Conference in Glasgow on the 2nd of July.

While fixed wing MAVs are energy efficient, their manoeuvrability is low. The new design would allow the flapping wing MAV to glide, improving energy efficiency and ensuring good images but when needed it can also slow its flight and manoeuvre in confined spaces.
"Although the models are not yet ready to be used, initial tests are positive and we hope that this design will combine the best of both worlds," says Mr. Thielicke.
