Swiss researchers have developed a robot called GOAT (Good Over All Terrains) that can change shape depending on the terrain. It moves like a rover, rolls in a spherical form to save energy, and crosses water obstacles by transforming into a floating object. This level of adaptability makes GOAT unique among autonomous machines. Rather than looking for detours, it chooses the most suitable way to move, reducing energy use and improving its ability to traverse terrain.
The developers took inspiration from nature: GOAT’s design combines features associated with spiders, octopuses, and kangaroos. The robot consists of a flexible frame made of fiberglass rods and four rimless wheels. Special cable mechanisms change its shape, while its sensors and processor are protected inside.
One of GOAT’s key advantages is its minimal reliance on sensors. Unlike other autonomous machines, which require numerous sensors and cameras, GOAT navigates using only satellite navigation and an inertial unit. This allows it to adapt effectively to its surroundings and find an optimal route even without precise knowledge of the terrain.
The creators see a wide range of potential applications for GOAT, from environmental monitoring and rescue operations to exploring other planets. The next step will be to develop algorithms to improve its adaptability and build the robot at different scales to suit specific tasks.
