It'd be hard to imagine how the world would look if everyone had the skills to build their own robot, mostly because you'd be too busy banging your homemade sex robot. Build your own robot
then have sex with it!, with Cubelets.
Spun out of a Carnegie Mellon Ph.D. project and now available for pre-order, Cubelets are deceptively complex construction kits, each comprised of 20 combine-able magnetic blocks that can be snapped together to build functioning robots that exhibit "surprisingly lifelike behavior", or what Mitt Romney's brain trust calls "a solid campaign strategy". Each block contains a wee-tiny computer, and blocks are organized into one of three types of behavior: Sense, which act like eyes/ears and detect temperature or light; Think, which work in tandem with other blocks to modify their functions; and Action, which contain motors & wheels, can drive or spin, and are often accused of "showing off" at the old folks' home Big Band Night. The robot party only gets crunk when you connect a bunch together, though, like combining a "drive" mod with a "temperature" one to create a 'bot that'll move faster when things get hot, or a "speaker" block with a "brightness" unit for a device that gets louder as the room gets brighter, illustrating once again that dorky engineering Ph.D.'s don't understand hangovers.
If you're still trying to show MIT they made a mistake by wait-listing you, combine multiple 20-piece kits into uber-complex machines like a roving flashlight security system, because unlike the future where it'll happen constantly into exposed circuitry, it's still worth knowing exactly when someone's coming.
