Cubelets are magnetic blocks that can be snapped together to make an endless variety of robots with no programming and no wires. 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.
Each cubelet in the kit has different equipment on board and a different default behavior. There are Sense Blocks that act like our eyes and ears, Action blocks, and Think blocks. Just like with people, the senses are the inputs to the system.
Unfortunately, at $160 for the first 6-piece kit, these are a little pricey, even though I’m sure they’re a lot of fun to play with.
