A team of roboticists at École Polytechnique Fédérale de Lausanne, working with a colleague from the University of California, has designed, built and demonstrated a bird-like robot that can launch itself into flight using spring-like legs.
The group describes their robot in a paper published in the journal Nature. Aimy Wissa, an aerospace engineer at Princeton University, has published a News & Views piece in the same journal issue suggesting possible ways the innovation could be used in real-world applications.
Some types of drones, such as those with rotors, can rise straight up off the ground—others that are powered with forward-facing rotors or engines that push exhaust out the back must either race along a runway or catapult to get airborne. For this new project, the research team developed a new design for getting such craft into the air—jumping using spring-like legs.
