Cubelets check all the “boxes” – from lesson plans to professional development we’ve assembled this handy administrator checklist to share with anyone involved in making an educational investment. 

Loved by educators from Vermont to Vietnam.

Cubelets are a great introduction to computational thinking. Computational thinking is a fancy term for the way computer scientists solve problems. It helps break down complex problems, and find repeatable solutions. Computational Thinking is just one of the many skills that educators love to teach with Cubelets.

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

How Cubelets work.

Just like building blocks only smarter.

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!

SENSE, THINK, ACT.

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.

There are three kinds of Cubelets - Sense Cubelets are black. Think Cubelets are a variety of colors - and Act Cubelets are transperant.

Connect to construct.

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.

 

Robots you can build with Cubelets robot blocks.

Pair blocks with bricks.

The yellow Brick Adapters connect to LEGO® and other brick building- block toys. Discovery Set includes one “studs” and one “sockets” adapter so you can build in any direction.

*LEGO does not support nor endorse this product. 

Get connected to code and create more.

Code new behaviors and more when you add a Bluetooth Hat to your Boundless Builder Pack.

Pair blocks with apps.

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

Data Logger.

Learn how Cubelets “talk” by visualizing block values or save the data for analysis.

Personality Swap.

Discover how swapping a Cubelet’s Personality changes the way it behaves.

Blockly Coding.

Build new Cubelet behaviors with drag-and-drop programming.

C Coding.

Build new Cubelets programs with text-based coding.

Specifications.

Recommended ages.

Cubelets are recommended for builders ages 4 and up. Cubelets are intuitive enough for preschoolers to start building robots, but they scale in complexity, teaching new skills as kids grow. Cubelets are even loved and used in university computer science programs!

Battery information.

The key to every Cubelets construction is the Battery Cubelet. A fully charged Battery Cubelet can power up to 6 hours of robot activity. Recharge the Battery using the included Micro-USB cable. When fully charged, the amber light on the Battery Cubelet will turn off.

Sizing.

Brick Adapters measure 32mm long x 32mm wide x 10 mm tall
