Researchers at the University of Michigan have unveiled SKOOTR, a revolutionary tri-pedal skating robot designed for highly stable locomotion. Unlike traditional three-legged robots, SKOOTR boasts exceptional stability without the need for a fourth leg, thanks to its innovative design inspired by both biology and engineering.
Talia Y. Moore, co-author of the paper introducing SKOOTR, drew inspiration from the omnidirectional maneuverability of rolling office chairs and the directional changes observed in brittle stars swimming. The concept merged the maneuverability of a ball-bot with the stability and versatility of a legged robot, resulting in a unique robotic platform.
The robot’s design features a large sphere at its core, surrounded by three robotic legs equipped with two joints each for flexion and extension. The central hub atop the sphere houses the necessary electronics, while the legs incorporate a hybrid contact mode with options for a rolling caster or a grippy rubber foot.
One of the key advantages of SKOOTR lies in its customizability. The central sphere can be easily replaced to accommodate different functionalities, such as storage compartments for object delivery or variations in weight to influence locomotion efficiency and stability.
Laboratory experiments have demonstrated SKOOTR’s exceptional stability and capabilities, surpassing those of conventional three-legged robots. Its ability to navigate obstacles and climb stairs showcases its potential for real-world applications.
Moving forward, researchers aim to explore the benefits of radial symmetry in robotics, uncover novel forms of locomotion, and develop open-source platforms for broader scientific use. Collaborations with neuroscientists highlight the potential for SKOOTR to contribute to interdisciplinary research, such as understanding the locomotion of octopuses.
SKOOTR represents a significant advancement in robotics, blending biological inspiration with innovative engineering to achieve unparalleled stability and versatility in locomotion.
