Stablized shooter & Claculating distance by vision

[Doron_Sivan]

Kevin, we need to get to the wanted rpm progressively. We could use only PID to get fast but progressively to the wanted rpm and then adjust it with F P and I. I didn't understant though what did you change in the I in your special PIDController.

this method works better if you correct for the distortion in the axis camera and if you use a larger image resolution. For us, this was accurate to within a foot on a 1/5 scale target 12 feet away. (which scales to almost full court for a regular target)

xmaams-
About larger image resolution we use 640X480 image resolution. but what do you mean by correct for the distortion in the axis camera??? can you explain how do you do that??
thanks!

And did anybody else here did the following stuff in a different way???
