Check out this shape-shifting device from MIT Computer Science and Artificial Intelligence Laboratory, that can walk, roll, sail, and glide using recyclable exoskeletons.

Dubbed “Primer,” the cube-shaped robot can be controlled via magnets to make it walk, roll, sail, and glide. It carries out these actions by wearing different exoskeletons, which start out as sheets of plastic that fold into specific shapes when heated. After Primer finishes its task, it can shed its “skin” by immersing itself in water, which dissolves the exoskeleton.
