Designed for all learners

Cubelets are the world’s first robot blocks! Uniquely designed, individual blocks are robots that snap together with magnets, teaming up to create thousands of novel robot constructions, each with new behaviors. Harnessing students’ natural curiosity, Cubelets captivate all ages* and scale to all skill levels.

*Cubelets are for builders ages 4+

Complex lessons made simple

Engaging and intuitive, Cubelets are an ideal point of entry into computational thinking. Students can design and redesign robot constructions with ease, using the robot blocks to model real-world behaviors and to launch students into a new world of creativity and critical thinking.

The building blocks of programming

Cubelets teach the principles of coding right out of the box -- no screens necessary. Students learn the basics of programming logic and troubleshooting as they build robot constructions, all without having to learn a single line of code. As they advance, they can apply these computational thinking skills to traditional programming, in Blockly or C, with Cubelets.
