Build steering robots when you combine the Blocker Cubelet with two Drive Cubelets. The Blocker makes it easy to have different parts of your robot construction respond to different data sources. The Blocker Cubelet is a basic building block that “blocks” data from its neighbors. It still passes power, but effectively stops communication and can insulate one side of a robot from another.

Ages 4+. Compatible with Cubelets OS4.
