R2D2 (Often spelled as Artoo Detoo or just pronounced as Artoo) is an Industrial Automaton astromech droid from the Star Wars universe. As an atromech droid, R2-D2 is designed to facilitate starship maintenance and repairs, with a multitude of tools and gizmos houses within his cylindrical chassis. He can walk on two stubby legs or use a third leg to roll between locations. He is one of the few characters to have appeared in every Star Wars film and has gone on to become a prominent character in the Expanded Universe both between the films' events and long after.
