Hexapod robot vehicle
Matt Denton of Hampshire, UK, built a huge hexapod walking machine that he operates by joysticks inside the cockpit. It took him four years and cost "hundreds of thousands of pounds" to make. Its top speed is one mph and, as you might expect, isn't particularly efficient. "It's not about miles to the gallon, it's about gallons to the mile," Denton told the BBC News.
