i really love robots, my brother and i used to build little ones as kids.
so i though this article about building robots that respond to human emotions.
what i really like about it is the way these guys look. the one shown above responds to emotions like a small child or pet, and he looks really sweet — like a handstitched little lamb, but with a heartbeat and a breathing belly.
the other one, the hexapod, is a little weirder. not as cuddly or friendly, and he "latches" on to strangers. bizarre! and accordingly, he's a pointy metal spider, kind of sinister — but still really neat.
