Building blocks for better thinking.

Log in to build.

The Cubelets' magnetic faces make them easy to snap together and separate. Each Cubelet has a special function. What you connect and how you connect them changes the behavior of your robot builds. Every combination is a new creation.

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

How do Cubelets work?

Just like building blocks, but smarter.

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

Build loads of simple robot construction with the Cubelets Discovery Set. Visit the Robot Ideas page for tutorials, samples, robots, and more!

FEEL, THINK, ACT.

Each Cubelet has a special function and falls into one of three categories: SENSE Cubelets take information from the robot's environment. THINK Cubelets calculates and modifies this information, and ACT Cubelets transforms this information into physical action.

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

Match blocks to bricks.

Yellow brick adapters connect to LEGO® and other building brick toys. Discovery Set includes one stud adapter and one socket adapter so you can build in any direction.

*LEGO does not support or endorse this product.

Associate blocks with applications.

The Bluetooth® Hat pairs robot builds with free Cubelets apps. Simple, proximity-based pairing makes connecting easy. Pair your creations with the Bluetooth® Hat to add new capabilities, read robot data values, and code new behaviors in Blockly or C.

• Data logger.
• Learn how Cubelets "talk" by visualizing block values ​​or recording data for analysis.
• Personality swap.
• Find out how swapping a Cubelet's personality changes the way it behaves.
• Block coding.
