Visitors can build their own R2-D2 replica by assembling the correct parts and programming it to do a certain task.

"Robotics is about mobility, control and perception," according to Connell. "Robots, if they are going to interact with humans, need to be able to perceive our world. But if they are going to talk to us they are going to have spectacular perception and Dr Brezeal is working on Kismet which can interpret our facial expressions."

On display is a Darth Vader costume that was used in the Star Wars movies along with a Stormtrooper outfit.

"We have a Stormtrooper costume and a lot of people must have their own Stormtrooper outfits because we have a team of volunteers who signed up to be part of this exhibition. We have a had a number of Stormtroopers marching through the exhibition and there are a few Darth Vaders around and the odd bounty hunter."
