Cubelets are magnetic blocks that come in three types: Sense blocks, Action blocks, and Think blocks. Sense blocks are black, Action blocks are clear, and Think blocks are in various colors. When assembled in a specific order, students create functional robots that move, beep, light up and react to different elements measured by the sensors.
Each Cubelet robot must have one Battery block which powers all the other one in the robot. The Battery block has an internal, rechargeable battery.
