The Hexapod Robot is is the closest thing I've seen to a real life Tachikoma. Not just because of its insect-like limbs, every aspect of its movement comes off as inquisitive, which gives a really impressive effect. It reacts to humans in a number of interesting ways. He follows your movement. Get too close and he'll lean back, looking a bit frightened or cautious. Apparently if you stay staring at him for a while, he'll take your picture and upload it somewhere. Neat project!
