This document provides an analysis of a four-bar linkage arm designed for a Logo Motion claw mechanism. It details the relationships between various angles and heights, including "ringer height" for approximate pickup height (4.5"), and feeder height (45"). The mate "deployment0-135" governs the claw and linkage angle, with a pickup position at 0 degrees and scoring at 135 degrees. The initial configuration is approximately 90 degrees. This model is intended for use in simulations and physical prototyping in design processes.
