Researchers at Caltech have developed LEONARDO (short for LEgs ONboARD drOne) or LEO, a bipedal robot that combines walking and flying for a new type of locomotion. LEO can perform complex movements such as walking on a slackline and riding a skateboard. By using multi-joint legs and propeller-based thrusters, LEO achieves exceptional balance and control. The researchers drew inspiration from birds’ behaviors when transitioning between walking and flying. LEO aims to bridge the gap between aerial and bipedal locomotion, allowing efficient movement in challenging environments. The robot’s lightweight legs support most of its weight, while synchronized control of the propellers and leg joints ensures balance. LEO can switch between walking and flying or use a combination of both. Future improvements include enhancing leg design, increasing propeller thrust force, and improving autonomy. The technology developed for LEO has potential applications in adaptive landing gear systems for aerial robots and flying vehicles. Read more
