The Cubelets Discovery Set is the perfect foray into the world of Cubelets® robot blocks. Open a box of little robots that will intrigue, fascinate, and inspire builders for hours on end. A unique blend of hardware and software, Cubelets make it easier than ever to explore robotics, coding, and other big ideas.

Cubelets make the principles of programming easy to learn and practice. Inside of each block is a part of a program – as you build your robot you build the code that controls its behavior. It’s hands-on coding!

Each Cubelet has a special function and belongs to one of three categories: SENSE Cubelets take in information from the robot’s environment. THINK Cubelets compute and change that information, and ACT Cubelets turn that information into physical action.

Connect at least one SENSE, THINK, and ACT Cubelet to create a robot construction.

Cubelets’ magnetic faces make them simple to snap together and pull apart. Each Cubelet has a special function. What you connect, and how you connect them changes the behavior of your robot constructions. Every combination is a new creation.

Block by block, robot by robot, Cubelets help develop vital skills.
