This resulted in three potentially viable linkage configurations that would maximize spring displacement. After careful consideration, we opted to proceed with the rightmost design.
** REV2-2** **REV2-4** **REV2-3**
During the design process, we realized that we were not considering the bearing ratio of our sliding link and were risking experiencing severe binding in our system. We adjusted the design such that we would have a bearing ratio of 1.5, yielding a link that was significantly larger in size than before. The position of the bearings was determined based off the idea of minimizing the moment of the lower links without making the assembly bottom out before full input link actuation. We also specified a location for our motor mount at the center of the link, a decision that would be changed later on in order to better accommodate our final cam design.
