Desktop Robot Cleaner Kit by Gakken
Ever wish you were a member of The Jetsons? While you can't travel to the year 2062, you can buy your very own desktop robot vacuum cleaner and at least feel like you've been transported to a futuristic utopia of tidy tabletops. It changes directions when it bumps into objects and senses any edge so you can leave it alone at your desk, table, or workspace and come back to a nice, clean surface.
There's no English manual so this kit's a bit more challenging than the other Gakken kits. The pictures, however, are fairly simple to follow and the kit should only take a couple of hours to build. The Japanese Manual (with pictures) is available for download here.
This kit requires 2x AA batteries which are not included.
