I saw it in Manchester in 1998- during the Computer 50 celebrations, when I met Tom Kilburn.

The winner was MiteeyMouse, a beautiful robot, built on its own PCB as its chassis and used a floppy disk drive controller as its microcontroller. After a respectable time learning the maze < 2minutes ??, it did another run - and ran it in, I'd swear, less than 15 seconds. It was like greased lightning, running at corners and going on diagonal tracks for higher speed.

What a target to aim for !
