These things look awesome. What you have here are building blocks that let you create cool robots by connecting sensors, motors, and feedback devices. The robots can even interact with the world around them. You won’t be building any kind of self-aware sentient being with these playthings, but your creation will be impressive as you “build with nature in mind”.
Cubelets snap together to form robots that can move, turn, detect or emit light or sound, as well as motion or temperature, they can also perform simple logic to determine what adjacent blocks should do. The blocks hold together magnetically, and automatically know what to do without any programming or wiring needed. At this point, there are 15 different Cubelet components you can work with, with more on the way.
The Cubelets kit is available from ModRobotics and you can pre-order it for $160 (USD). For that price, you get six Cubelets, two sensors, two “action” blocks, and two “brains” with a battery pack. The large kit costs $520 and includes 20 pieces. They’re designed for kids eight and up and run on rechargeable batteries. (Charger sold separately for $15.)
Sure they’re expensive, but how else are you going to build your robot cube by cube? The possibilities are pretty endless. Once the price comes down and more blocks become available, I’d love to see what can be accomplished.
