First of all: this thing is SO awesome.
The making of this amazing walking bipedal robot is documented in a rapid series of photographs strung into a video. The robot is made almost exclusively of paper, with the exception of some wooden shafts and an elastic band which serves as the power source.
I wonder if the design is based on (or at least inspired by) one of the many tin toy wind-up walking robot designs. It would be nice if I could read the site. Perhaps I will try Google Translate a bit later.
The gears look like they are solid, as if perhaps made up of many sheets of paper glued together in a thick stack. You can spot a crown gear in there if you watch closely. There are some really ingenious construction techniques. This is worth viewing more than once. I think I want to try working in paper sometime soon.
There are PDF files available for download on the site and they may be plans. I haven't had time to explore them yet. If any of the good readers of The Automata Blog finds out what we are dealing with here, please post a comment or drop me a line. Thanks in advance for your help!
