The Cubelets Creative Constructors PLUS Pack is Modular Robotics' large-format classroom kit built around 78 magnetic robot blocks. Each Cubelet carries one piece of a program, so as students physically snap blocks together they are simultaneously building the code that drives the robot's behavior. Every Cubelet falls into one of three families — SENSE blocks that read the environment, THINK blocks that process that information, and ACT blocks that produce motion, light, or sound — letting learners grasp robotics and computational thinking with no screen required for the youngest builders.
RobotLAB supplies this pack for classrooms that want a single set rich enough to serve a full class at once. The 78 Cubelets are sized to support six simultaneous student groups (most educators run groups of 3 to 5), and the kit ships with 6 Bluetooth Hats so every group can program their robot, swap personalities, and run remote-control challenges. Brick Adapters bridge Cubelets to standard LEGO-compatible bricks, and a 5-port charger, charging cables, and storage tubs keep a whole class powered and organized. The blocks scale from screen-free building for PreK up to block coding and Python/JavaScript for secondary students.
As a robotics integrator rather than the manufacturer, RobotLAB sells, configures, and supports this pack nationwide and pairs it with the free standards-aligned lesson plans, activity cards, and professional-development resources that come with every Cubelets set. Note that Modular Robotics has since positioned the newer Clever Constructors Pack as the successor configuration; RobotLAB can advise whether the Creative Constructors PLUS Pack or a current equivalent best fits your program and budget — call 1-87-RobotLAB to confirm availability.

With enough blocks for six concurrent groups, this pack outfits an entire class for a robotics or computer-science unit. Younger students build steerable robots screen-free, while older students layer on block-based coding and text languages — one kit covers an unusually wide grade band, from PreK through high school.
The snap-together, tool-free format and LEGO-compatible Brick Adapters make Cubelets a fast, low-friction station for drop-in makerspaces and library programs. Storage tubs and a single 5-port charger keep the set shareable across rotating groups without a dedicated lab setup.
Because the blocks are physical and the youngest activities require no screen, Cubelets support tactile, hands-on learning for diverse learners. Open-ended building and immediate cause-and-effect feedback make the kit well suited to inclusive and special-education settings.
The pack's group-based design fits robotics clubs, summer camps, and enrichment programs that need a robust, reusable set. Bluetooth Hats enable programming challenges and remote-control races that keep mixed-age, mixed-skill groups engaged.
78 Cubelets: 12 Distance, 12 Drive, 9 Battery, 6 Brightness, 6 Blocker, 6 Flashlight, 6 Passive, 6 Rotate, 6 Inverse, 3 Threshold, 3 Knob, and 3 Bar Graph. Plus: 6 Bluetooth Hats, 8 Brick Adapters (3 sets of 4), 1 5-Port Charger, 5 Charging Cables, and 3 Storage Tubs.
Same-day response. We handle delivery, on-site setup, staff training, and ongoing service nationwide.
It includes 78 Cubelets robot blocks (12 Distance, 12 Drive, 9 Battery, 6 Brightness, 6 Blocker, 6 Flashlight, 6 Passive, 6 Rotate, 6 Inverse, 3 Threshold, 3 Knob, and 3 Bar Graph), 6 Bluetooth Hats, Brick Adapters, a 5-port charger, charging cables, and storage tubs. For an exact current packing list, call 1-87-RobotLAB.
It is sized for six student groups working at once. Most educators find groups of 3 to 5 students work best, so the pack comfortably serves a full classroom in a single session.
Cubelets are designed for PreK through 12th grade and recommended for builders ages 4 and up. The youngest learners build screen-free, while older students can move into block-based coding and Python or JavaScript.
No. The core experience is screen-free — students learn by physically snapping blocks together. The 6 Bluetooth Hats unlock optional on-screen programming, personality swaps, and remote-control challenges for groups ready for more advanced work.
Clever Constructors is Modular Robotics' newer classroom configuration and the successor to Creative Constructors PLUS. Both support six groups; the packs differ in exact Cubelet counts and price. RobotLAB can help you choose the right current option — call 1-87-RobotLAB.
Yes — included Brick Adapters let Cubelets connect to LEGO-compatible bricks. Every Cubelets set also comes with free standards-aligned lesson plans, printable activity cards, and online professional development.
Yes. RobotLAB sells, configures, and supports Cubelets nationwide and can bundle training and curriculum support. Call 1-87-RobotLAB for a quote, availability, or to confirm the best-fit pack for your program.
