Re: FIRST Team 2980's 2012 Open Source Robot

its not the motor...9013...its the planetary gear box that seams to be the problem. We have two of the 9013s...just no planetary gear boxes.

Sort of hoping they will either come back in stock or someone will have two that they are not using.

I guess...lesson learned...we'll buy a ton of stuff in the off season just in case for next year.

We may go with the AM gearhead motors...

So we are doing some math to try and figure this one out...

We want the ball moving at up to 27 fps when it leaves our shooter...

So...we figure if 50 percent of the wheel speed goes into the ball as it passes through the shooter...

so rotating 8 inch diameter wheels 3 times a second? so basically we would have to have the wheel spin 4 times as fast as the motors?

my brain hurts at this point...
