I built a little test stand to work on the mechanism that will impart movement to the rhinos. This version might be a little large on the amplitude side, so I might try an alteration tomorrow. Given the right amount of rocking the jockey might not need to be pushed by the pushrod, although a little lead in his behind might be needed. I also need to increase the motion of his legs.
Here is a video of the version one test of motion of just one rhino.
Automata is a creative blend of my life interests , engineering, art and woodworking.
