In order to optimize our linkage sizes to obtain our desired motions, we used the Phase Space motion capture system to record the relative angles of shooting motion.
Two L.E.D. sensors were placed around the shoulder, elbow and wrist joint in order to find the intersection where the joint would be. The data was processed using Excel and MatLab. A polynomial fit equation was derived based on the data and was fed through an optimization program on SolidWorks. Currently in progress.
