This science kit is a real laboratory that you can use to build a SumoBot that never falls! When placed on a table, this advanced robot moves and recognizes the empty spaces beneath it. It stops and changes direction as soon as the rubber wheel detects that there is no more surface to walk on! The upper part of SumoBot is transparent so that children can see all its technology and internal gears, thus teaching the mechanisms that allow the robot to move in this way.
