Science Museum, London – August 25-27
Okay, not strictly anything to do with games, but this exhibition does have a robot and that's the next best thing. KASPAR is apparently a new child-like humanoid 'bot created by scientists at the University of Hertfordshire, to aid children suffering from autism. It's part of the wider Robot Cub project which is carrying out cognitive research through the use of robotic systems.
But if that's not the droid you're looking for, the exhibition will also feature Phantom, a force feedback device that lets users to touch objects in the virtual world, and IROMEC, a robotic toy for children with disabilities.
