Robotic Bat Wing Uncovers Flight Secrets for Aviation
The strong, flapping flight of bats offers great possibilities for the design of small aircraft, among other applications. By building a robotic bat wing, Brown University researchers have uncovered flight secrets of real bats - the function of ligaments, the elasticity of skin, the structural support of musculature, and skeletal flexibility. The robotic wing is designed to flap while attached to a force transducer in a wind tunnel. As the wing flaps, the force transducer records the aerodynamic forces generated by the moving wing. By measuring the power output of the three servo motors that control the robot?s seven movable joints, researchers can evaluate the energy required to execute wing movements.
