It'll be a while before robots are ready to lord it over us, trust me. (I have worked on some that were potentially deadly; but they were bolted to the floor, and hence, rather easy to outrun ;-) )
This one's body includes an old external hard drive enclosure.
This one's body is made with Legos (but not MindStorms). Its "muscles" (i.e., servos) and brain are made from Parallax parts.
This one is a "Tab Electronics Build-Your-Own-Robot Kit" with modified wheels.
I like to attend Connecticut Robotics Society meetings when I can. Which unfortunately isn't very often (over 2 hours of driving, round trip).
