Researchers in Switzerland have devloped something they are calling the Cubli. Using a sophisticated system of wheels and motors, the Cubli is a 15cm cube that can balance on its corner, jump, and "walk" on its own. Because of the sophisticated mechanics inside, it can stabilize itself in microgravity, making it ideal for various tasks in space.
More worrying is that, according to the disconcertingly soothing narrator, they can be used for self-assembling robots. If robots no longer need humans to construct them and repair them, how long before they figure out that they can wipe us out, or enslave us? Artificially intelligence is already making leaps and bounds. Can you imagine Siri's "brain" in a body constructed of Cubli bits?
Maybe it's not the zombie apocalypse we should be worrying about - maybe we should be concerned with the robot apocalypse.
