Description: The Knob Cubelet has a potentiometer embedded in one of its faces. It outputs a 0 when turned fully counterclockwise, and a 1 when turned clockwise.

Cubelets are magnetic blocks that can be snapped together to make an endless variety of robots. You can build robots that drive around on a tabletop, respond to light, sound, and temperature, and have surprisingly lifelike behavior. But instead of programming that behavior, you snap the cubelets together and watch the behavior emerge like with a flock of birds or a swarm of bees.

Note: Cubelets require a special battery and charger. You will need to purchase the charger separately.

  • Wow, these are extremely expensive. You’d be better off with an Arduino or equivalent and lots of various sensors and such. The idea and design is quite impressive though.

  • Elegant idea, now they just have to work on the prices. For the price of 3 or so cubelets I got the RedRobot kit and have a much more capable robot. The only way to justify the cost of this is the labor saved in wiring up a prototype, but this doesn’t seem to be a professional grade proto system and would never be used in a situation where labor cost matters.

    Get the cubelets down to $5.00 or less each and it’s got a chance.

    • I agree. If they were 5 bucks a pop, I’d get 20. These look awesome, I just wish I had the money to get enough to make something cool…
