  Dual Cyclic Animatronic Mechanism

Use this unusual twin-cam mechanism to create eyes, ears, and other animated parts for your robot. Rotating a single 5/8" diameter input gear causes two 4" long plastic leafs to flap up and down in unison. Maximum movement distance, measured at the end of the leaf, is 4.5". The plastic leaf material can be cut to length, or replace with a section of thin metal, plastic, or wood.

One idea for this cyclic mechanism is to move animatronic eyes on a humanoid robotic head. As a motor turns the gear, the eyes move up and down or side to side. The mechanism might also be useful as legs or arms in a lightweight BEAM-style robot.

Made of lightweight nylon plastic; weight is a mere 6 grams.
