What can fly like a bird and hover like an insect? Your friendly neighborhood hummingbirds. If drones had this combo, they would be able to maneuver better through collapsed buildings and other cluttered spaces to find trapped victims. Purdue University researchers have engineered flying robots that behave like hummingbirds, trained by machine learning algorithms based
Unmanned underwater vehicle (UUV) power experts at Applied Physical Sciences (APS) Corp. in Groton, Conn., are moving forward with a project to develop a highly customized high-performance battery system prototype to enable manned and unmanned undersea vehicles to move through the water faster and more energy-efficiently than ever before. Officials of the Naval Undersea Warfare
To build more aerodynamic machines, researchers are drawing inspiration from an unlikely source: the ocean. A team of evolutionary biologists and engineers at Harvard University, in collaboration with colleagues from the University of South Carolina, have shed light on a decades-old mystery about sharkskin and, in the process, demonstrated a new, bioinspired structure that could
