The Cubelets are divided into three different types-action (outputs), sense (inputs), think (logic)-with various names like 'battery,' 'blocker,' 'temperature,' and 'distance.' By learning what each one does and clipping them together in a variety of ways, kids can build robots with different functionalities that are reactive to light, sound, and temperature, and can even drive about. Before you get too excited though, the $160.00 price tag for a set of eight might dissuade :-(
Neverthless, it's pretty elegant the way he has the self-contained electronics to correctly figure out what resources the blocks are plugged into. But on the other hand - it's too basic a functionality to be more than a novelty for little kids or a talking piece on a coffee table. It needs a bit of versatility with it's simplicity -- like a way to 'tune' each piece like Lego Mindstorm. Something as simple as having behaviors -- perhaps as little geometric shaped pins that could be added to each block, so that you could have a bit more intelligent programmability without needing a programming language. And it also needs a remote control :-) And..BETTER PRICE OF COURSE!!!
