Cubelets are magnetic blocks that you can snap together to make an endless variety of robots with no programming and no wires. Cubelet-based robots can drive around on a tabletop, respond to light, sound, and temperature, and have surprisingly lifelike behavior.

Each Cubelet is an 8-bit computer, which means that when they are snapped together in a robot construction, they form a computer network.

History

Cubelets were first introduced in 2010. They were created by startup Modular Robotics, a spin-off from Carnegie Mellon University, where founder Eric Schweikardt invented Cubelets while working on a PhD. Designed as easy-to-use snap-together blocks, Cubelets have found wide adoption in schools and STEM programs. In 2019, Modular Robotics acquired Dexter Industries, another educational robotics company. In addition to Cubelets, the company now offers several different robotics kits.
