So, yea, 5.



A pair of connected linkages (driven by miniature pistons).

The first 4 states are obvious: main arm position and speed, shooter mini-arm position and speed. What are the other two? How'd you go about tuning that? With that level of complexity, I imagine you had to go to model-based control?
