GOAT Robot: Shape-Shifting for Superior Terrain Navigation

Researchers at EPFL have developed GOAT, a bio-inspired robot capable of dynamically altering its shape to navigate diverse terrains. Unlike traditional robots relying on complex path planning and numerous sensors, GOAT efficiently traverses challenging environments (rough terrain, water) by morphing between a flat rover and a spherical shape. This shape-shifting, combined with compliant materials, minimizes energy consumption. For example, it can roll downhill passively to save energy, or swim through obstacles. Inspired by various animals, GOAT uses inexpensive materials. Future applications include environmental monitoring, disaster response, and even extraterrestrial exploration.
