Looking for ideas?
Nothing like insulting the unpaid help! before they start :-) happy New year everyone.
OK A friend has a model of a fair ground ride, this is a steam yacht, http://www.youtube.com/watch?v=zp76RTbqqLk
he wants to animate this and would like the motion to be realistic at the scale size. He had tried a number of mechanical solutions, cranks etc but they all give a jerky motion and the real thing is very smooth.
I am inclined to think this is a micro processor solution with either a suitable servo motor or similar driven to mimic the inertia of the real thing.
