Re: FRC 2012 Ball Launcher by iR3
nice job! good music, too.
would you be willing to do some controlled tests to compare it against my trajectory spreadsheet and post the results?
Mostly, I'd like to see you use your fixture to estimate launch velocity based on range. Mount that sucker to a desk to make it the right height and lock down the angle on it. Feed the balls as nicely as possible and check the distance traveled against numbers from my sheet. It will go a long way to helping us figure out what the drag effect will look like.
