A spherical robot with 32 legs that 'moves like an amoeba' could be used to explore planets or in disaster response missions. It can control all of its legs independently to move swiftly and allows for a stable and controllable form of locomotion. It resembles the tensegrity robots that Nasa is building for planet exploration and is based on a shape called a rhombic triacontahedron - a polyhedron with 32 vertices and 30 faces made of rhombuses (or rhombi).
