Build your own Gakken crab-bot
What? As if you didn't already know Japan's robots (and toys) beat our robots (and toys). So don't act surprised that for a mere ¥6,000 (about $55 US) you too can have a metal walking crab-robot. Sure, it only walks back and forth,
but it does have an IR control and looks potentially hack-able. Just don't go making some kani-maki out of it,
mkay?
