I’ve all but finalised the linkage on my paper dog project. As well as moving the legs up and down the dogs head moves back and forth. All the parts are connected together using simple strips of paper which seem to be quite effective. You can see the dog mechanism in animated action in this Instagram clip.
I need to make a couple of small adjustments to the geometry of the movement then it is just a case of fitting the dog to the gearbox mechanism. Woof!
