GOAT is a cutting-edge robot designed to modify its shape for efficient navigation across different terrains. It fluidly shifts between a flat, rover-style setup for driving and a small, spherical shape for rolling, maximizing energy efficiency and versatility. Drawing inspiration from animal locomotion, GOAT maneuvers around obstacles without depending on sophisticated sensors, opting instead for straightforward navigation methods and engagement with its surroundings. With promising uses in disaster relief, ecological surveillance, and extraterrestrial exploration, GOAT presents a revolutionary method for robotic movement.
