This original science kit is a real laboratory you can use to build a really special sumo robot which never falls off the edge! When placed on a table, this advanced robot moves and recognizes open spaces underneath it.
It stops and changes direction as soon as its rubber wheel detects that the surface underneath it is no longer there! The upper part of the Sumo Bot's body is transparent so you can see all of its internal gears and teach children about the mechanisms that allow the robot to move around.
