Re: Modeling Ball Shooters

This seems to suggest the work being done by the motors while the shooter is under load helps keep the shooter up to speed. Now, how to account for this work in the model for a generic shooter is beyond me. I feel like this is a constant or series of constants that would have to be empirically derived.
Alternatively, it could be that the additional rotating mass of the second motor provides a greater flywheel effect, decreasing the RPM drop of the system when the ball enters it. Not saying definitively this is the explanation, just offering an alternate reason to explain your observation.

This could be completely off base though, depending on how much of the energy is tied up in the shooting wheel versus motors, should probably just break out the math when I get a chance this evening :/
