Tiny robot that can both fly and swim
In a first, scientists have developed an insect-sized robot capable of both flying and swimming - a major advancement towards a “flying submarine” -- a vehicle that can seamlessly transition from air to water and back again.
New York: In a first, scientists have developed an insect-sized robot capable of both flying and swimming - a major advancement towards a “flying submarine” -- a vehicle that can seamlessly transition from air to water and back again.
Developing the bot called “RoboBees” required a combination of two contradictory designs -- of aerial and aquatic vehicles.
Aerial vehicles require large airfoils like wings or sails to generate lift while underwater vehicles need to minimise surface area to reduce drag.
To solve this, engineers at the Harvard John A. Paulson School of Engineering and Applied Science (SEAS) took a clue from puffins.
The birds with flamboyant beaks are one of nature’s most adept hybrid vehicles, employing similar flapping motions to propel themselves through air as through water.
