1. First BIRD Prototype

The first prototype was a basic crank rocker assembly replicating the below picture. Other designs came into play including a crank slider mechanism in order to acquire a clapping motion in the flapping mechanism. This would result in more efficient lift force, but a cost benefit analysis would render this not possible. In order to create the mechanism, expensive material would be needed for light weight and strong fracture strength. This problem led to the ultimate decision of pursuing a crank rocker mechanism for the flapping motion. This mechanism is commonly seen in commercial RC birds and is replicated in the following video:
