Description: The Minimum Cubelet can accept any amount of data, but only outputs the smallest value that it receives. It can be handy for creating an on-off switch for a robot and also for using with a Distance Cubelet to build robots that avoid falling off the edge of a table.
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.
