VIDEO/STILL CAMERA The video/still camera in R2-D2’s head allows him to take snapshots and short video clips, which can be stored on your mobile device. His programming also includes the ability to detect human faces. PROJECTOR Just like in the Star Wars movies, R2-D2 is able to display holographic messages using a projector which can beam images of Princess Leia and Luke Skywalker onto any nearby flat surface. POP-UP LIGHTSABER As in ‘Return of the Jedi’ R2-D2 has a ‘hidden extra’ – Luke Skywalker’s lighsaber, which will pop up on demand from the pneumatic ejection tube in his head. EXTENDING ARMS As in the movies, R2-D2 can extend his spacecraff linkage and control arms on comman.The flaps on his body conceal hidden droid manipulator arms and probes, which you can extend at will. ------------- Mail: customercare@deagostini.co.uk
