Executive Summary
Researchers at Carnegie Mellon University have developed a climbing robot named Loris, designed to operate in challenging real-world environments.
Loris utilizes a novel adhesion mechanism called microspines, inspired by cockroach spines, which allows it to grip rough, rocky surfaces where suction or magnets would fail.
The robot's design incorporates principles of under-actuation and passive grippers to minimize mass and complexity, making it suitable for its primary application: space exploration.
The key mission for Loris is to navigate steep cliffs and subsurface caves on the Moon or Mars, enabling access to geological data and samples previously unreachable by wheeled rovers.
