More on Push Up Automata…

Sat, 11 May 2013

Smelter and Coolio both drew my attention to this paper model of a push up character on a Japanese karakuri website.

Unfortunately it is impossible to tell from the picture just how it is driven. One thing is for certain though, the drive is through the feet, not the arms just as in my proposed model.


This plastic, wind up model which I found on the Hawkin's website has powered arms.


Master automata maker Paul Spooner produced this delightful model some years ago, again driven via the feet.


This time a circular cam with a slot round its circumference pulls on a string as it is turned, in turn this pulls the feet and lifts the body.


Pneumatics power…


…and hydraulics power and both beyond the scope of paper projects. So far.


Cam power, however, is not as per this model that I produced for a company some years ago which appears to be no longer in print.


So we come back to the design I'm working on now. It is fascinating to see how your approach to a similar problem changes over the years.

      after opening the page in a different  browser i was able to translate the top of the page and it seems this model is driven by a crank.here is the rough translation of the top of the webpage

      "and I am very happy to be able to provide to you, the joy of creation. The contents of the paper trick is, aluminum wire original paper, manual, move. Cap (different by a product, but the string, stainless steel wire,) contains. This series is interesting trick ferns workshop is to give everyone wake up to the fun of the crank. To Purezennto birthday, also, to the creation of his collection please the paper trick children and adults to enjoy!"

      Thanks! Nice bit of research there. – RI
