Desktop Robot Cleaner Kit is a set from Gakken used to create a desktop cleaner robot. The desktop cleaner robot 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 Desktop Robot Cleaner Kit is 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.
This kit requires 2x AA batteries which are not included.
Gakken is a Japanese publishing company founded in 1946. In the 1970s, they began selling educational toys, books, magazines, and electronic kits. Their kits are known for their smart design and relative ease of use and have a large cult following both in Japan and the United States.
