For now, it’s only the head in a custom-made R2-D2, but soon the whole astromech will obey the orders of an iPhone, including the possibility of firing sounds and sending text to its head displays.
The controls use either the iPhone’s accelerometer or the multitouch screen, and if rumors of a magnetrometer in the next gen iPhones are true, we could be looking at some very interesting robot applications both in the App Store and in the jailbroken universe soon.
