Also on display is the artificial retina which "will be a revolution" once perfected, and the Australian-developed Cochlear device which allows people to hear better.

The robot pattern recognition and facial expression exhibition and walking device are also interactive.

"You have to make the robot walk by adjusting the dials and getting suspended robot legs to walk like a human requires intense concentration," Connell said. "It gives you an idea of how complex it is to get robots to walk. It's incredible to think how complicated our human technology is to be able to walk."

"There a lots of these interactives designed to make people think about the technology."

Star Wars Where Science Meets Imagination will be on at the Powerhouse Museum in Sydney until late April, 2009.
