On a small stand in the middle of a packed hall previewing the biggest technology launches for 2007 stands a Korean guy. He's holding what looks like those sampler boards you see in B&Q, with small blocks of wood stuck to the card.

He then shines a blue light onto one of the squares. An image (presumably a letter of some sort) suddenly appears on the block of wood. This image is the thing Ubot will see when it travels around your home. The image will tell Ubot what to do next, and according to the Korean guy, 'construct a navigational algorithm and operate successfully without missing an area'.

Oh. We see. In the packed CES event, we couldn't find out if the Ubot floor vacuuming and mopping robot is heading for British shores. But we did find out that Korean builders are already building the hidden messages into the walls of their nation's homes.
