Scientists and engineers at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland are developing an “uncrewed aerial vehicle”, aka a drone, with fixed wings and bird-inspired legs. Most drones are powered by four rotary wings and can take off and land from just about any surface, but they are not the most energy efficient […]
Over decades of research and development, engineers have been working on designing and building robots that can walk and run as well as animals and have built many devices capable of independent movement. Max Donelan of Simon Fraser University, Canada and colleagues from various USA universities carried out an extensive study of running robots comparing […]
Alan Pan, an engineer based in Los Angeles, USA, has designed and built a device that enables snakes to walk on four legs. The device consists of a long tube open at both ends that a snake can crawl into. Attached to this are four robotic legs, each fitted with servomotors. The walking pattern is […]
