Re: Wildstang 2012: After The Game
Hi Steve,
Thanks for posting these. I took a look at the #6 video (shooter), and several questions came to mind, if you'd be willing to share some more detail:
- with the 7:1 speed reduction and the 550's free speed of 19300 rpm, the top speed of your wheel would be somewhere around 2700 rpm (neglecting gear losses). What was your operating speed for shooting?
- what kind of speed control algorithm did you use? e.g. PID, bang-bang, voltage compensated open-loop, etc
- how long was your spin-up time from 0 rpm to operating speed?
- did you keep your wheel spinning continuously during the entire match, or did you spin it up when ready to shoot?
- what were your two launch angles?
- did you measure your actual launch speed?
