These models are from the templates in a book called Paper Automata by Rob Ives. I was impressed at the sturdiness of the finished models – everything is made in multiple layers and reinforced with 3d bars. The moving parts are all done in such a way that the movement is controlled at all times and joints won’t wear with use.
The book has four models to make all with different mechanisms. The first two here are the motley man who takes a bow with a flourish and three little jumping sheep. See below for some videos of each.
