Re: FRC 3357 shooter arm
To fill in a few more of the numbers, yes it is a modified 4-bar linkage. The front arm has roughly 120 degrees of rotation and we have it tuned right now so at the peak, the shooting deck is at about 43 degrees above flat. To initiate the upward movement we are exerting over 100lbs to "break" the linkage from the locked position. After the first 15 degrees of rotation by the front arm it gets much easier. I will see about getting our design manual loaded online for people to look at as we have the math behind our robot design there.
