Future Robots. Robotic Snakes & Worms Get Under Your Skin. The modular snake robots being designed at Carnegie Mellon University can move in a variety of ways: slither, roll, swim, and climb straight up. They can spiral forward to fit through a narrow space such as a pipe, or they can wind themselves around a pole or tree and slither up. To move across a flat surface, they move up and down like an inchworm.
