Experts spend years trying to build robotic systems that can both fly and dive.

Robotics researchers regularly turn to the natural world for inspiration, and those working on machines that fly are no different. An international team of scientists has taken this approach to ...

(PhysOrg.com) -- According to a new Cornell study, an optimized flapping wing could actually require 27 percent less power than its optimal steady-flight counterpart at small scales. In the search for ...

Small migrating birds save energy as they fly. Large birds, such as storks, save energy on the flight to their wintering grounds by soaring through the air on thermal currents. Until now, however, we ...
