Miniature Automaton : Part II

Assembled prototype with wind-up controller

The controller prototype crankshaft is attached to a small music box movement with the musical comb removed to gain more torque. The linked pennies produce a wave type of motion, which is more natural than the earlier design that used a bent wire shaft. Sankyo makes windup mechanisms with an output shaft which is used to attach the mechanics. The small 18 note Sankyo music box has very little power, in order to have more than one motion a smaller, lighter armature is required, resulting in mechanism designs using counterbalancing springs and cables that require very little power to move the figure.

The finished mechanism is assembled with magnifying glasses and surgical tweezers.


Created with the Support of Creative Pinellas and the Pinellas County Board of County Commissioners;
the City of St. Petersburg Office of Cultural Affairs and the St. Petersburg Art Alliance.
