not world's first (Score 1)

There was a *more impressive* origami robot built by a technician who works for Toyota in Nagoya, Japan a few years ago. It was for some kind of showcase they were having.. he built it in his spare time. Most impressive thing about it was that it created a paper crane, then unfolded it back to its orginal form - a flat sheet of paper (and continued this loop). They found that the only way they it could do this was by using washi, which is traditional hand made Japanese paper.
