Caltech's researchers have achieved a groundbreaking feat by developing LEO, a bipedal robot that combines walking and flying capabilities to create a unique form of locomotion. LEO, short for LEgs ONboARD drOne, represents a remarkable achievement in robotics, as it exhibits exceptional nimbleness and the ability to perform complex movements. By incorporating multi-joint legs and propeller-based thrusters, the team at Caltech's Center for Autonomous Systems and Technologies has enabled this robot to achieve precise control over its balance and movement.
In a recent paper published in Science Robotics, the innovative design and capabilities of LEO were unveiled. Drawing inspiration from the behavior of birds that effortlessly navigate between walking and flying, the researchers sought to understand and learn from this natural phenomenon. The goal was to bridge the gap between these distinct modes of locomotion and unlock new possibilities.
This robot's hybrid locomotion approach, which blends elements of walking and flying, offers a unique advantage. Its lightweight legs provide crucial support, reducing the strain on the propellers. By synchronizing the control of the thrusters and leg joints, LEO achieves remarkable balance and stability. With a height of 2.5 feet, it features two legs equipped with three actuated joints, along with four propeller thrusters mounted at an angle on the robot's shoulders. This novel combination allows it to seamlessly transition between walking and flying modes, resembling the coordinated movements observed in nature.
