Everything you need to get started, explore free lesson plans, and see how Cubelets fit your classroom — all in one place.
Cubelets are designed to be intuitive — most educators start building robots within minutes. Every robot needs a Battery Cubelet (gray), at least one Sense Cubelet (black), and at least one Act Cubelet (clear). Snap them together magnetically and the behavior emerges from the construction.
Plug the Battery Cubelet into any micro-USB power source. The amber LED turns off when it's fully charged.
Connect a Sense (black), Think (colored), or Act (clear) Cubelet to the Battery. Flip the switch and watch it go.
Swap blocks, change orientations, add more Cubelets. Every arrangement produces different behavior.
