The primary objective for this automata project was to get as much action as possible with just one source of motion. The action is movement of both legs and both arms. The source of motion is a hand crank which operates a crankshaft very similar to those found in automotive engines. A secondary objective was to hide the motion as much as possible to make the action figure look like it was happening on its own.
The frame for the project was designed to allow as much viewing of the mechanical movements as possible. The frame consists of two base plates with wood dowel rods for supports.
We’ll begin by making the bottom plate. The dimensions are given below.
