Ever seen the little kit you can buy, it contains the nitinol wire and
enough small bits to create a little hexapod. All you need is solder and an
iron. Then you make the little bug with the instructions, apply a current
via AA battery and the little hexapod walks!! It's soo cool and so small.
Just picture making a bug just with paper clips and nothing else, that's
sort of what the hexapod looks like. Real small and minimal with no apparent
moving parts. We built one when I used to work at the Science Center. I
wonder who makes the kit? I forgot.
