Today I discovered something I'm sure uncle Ken would have been very impressed to see: http://www.gizmag.com/rex-robotic-exoskeleton/15736/. And there's a video of the device in use too:
Robert Irving and Richard Little deserve every success with this device. It may not be fast, but it is clearly a device that has enormous potential, and I'm sure REX 2, when they build it, will be stronger, faster and lighter.
Well done guys.
