Cubelet Robot Kits

Cubelets are small blocks that are snapped together to make an endless variety of robots with no programming, no small parts to track, and no wires. The small magnets on each side of the cube attract to each other. Each cube has its own special function.

They detect each other and communicate with each other, like a flock of birds.Teaching STEM lessons with cubelets gives students a reason to apply knowledge they've already learned, to verbalize it, and to put into practice new vocabulary and literacy skills about engineering, problem solving, science, and technology. Watch this video to see how they work.

The cubes can also work with lego blocks to easily add motorization, sensors, and engineering functions to any creative endeavor.

Making Robots with Magnets

You don’t need to know how to code or wire to construct robots with Cubelets. Snap the robot blocks together and the magnetic faces do the rest. Every unique arrangement is a new robot with novel behaviors emerging from the construction. Invention is made easy with cubelets.


How Durable are Cubelets?

Cubelets are tough! Sure, you can break them, but it won’t be easy. In addition to passing CPSIA and ASTM toy safety standards, the durability of this product has been tested in classrooms, and teachers tell us that they are impressed with how Cubelets perform over time.Cubelets have been in classrooms, after school programs, makerspaces, and science centers where they’re used repeatedly for hours at a time, and they hold up to exuberant, clumsy, and continuous use. You can also wipe them down with a disinfectant from time to time, although we don’t suggest submerging them in water to clean them!
