Someone asked me how the movement of the Ningyo-Joruri puppet head that I made during Nori Sawa’s masterclass a few years ago worked , so I’ve drawn a diagram on my iPad to illustrate the mechanism. It makes more sense if you look at in context with my photoset from the class, and perhaps with the original blog post.

I have a couple of other insect garden spikes, a bee and a dragonfly (bought out of curiosity when I was working on making giant bees and dragonflies a few years ago). They are much smaller than the spider, with bodies about 7 cm long, and the wings are on double springs. The dragonfly has much lighter springs, and a much better incidental movement than the poor bee, whose springs and wings are way too heavy.

A number of the figures have hand made automata mechanisms. These have been designed and machined by the artist, and consist of ‘an internal crankshaft, which enables the Automaton to operate at varied speed, in forward or reverse. The brass hand-crank mechanism operates a counterbalanced armature, creating a rhythmic side-to-side motion with alternating leg kicks’. In the automata gallery are three monkeys, Cecil and Emo, and the mad scientist Dr. Messmore, MD. With the last, the artist has been developing ‘a programmable automaton using servo electronics controlled by a laptop computer’ enabling ‘customized movements, essentially creating one-of-a-kind moving figurative sculptures‘. Its described as an ongoing process, in which the ‘ultimate goal is to have the automaton operate independently of the computer, evolving from an educational tool to an art object desired by collectors of automata’.
