Crab sphere is the self-returning ball of the future

This Transforming Crab Sphere

If you've ever chased a runaway ball down the street you'll appreciate Kåre Halvorsen's MorpHex sphere which can transform into a six-legged crab and simply walk back to you.

The bot is still under development, but in its current form it's brought to life with 25 servos that let it walk, dance, and do everything but roll around when it's closed up into a sphere. That feature is hopefully coming soon, but even if this ever became a DIY kit, the custom electronics and components used means it wouldn't be cheap.
