Due to the relative light weight to the size of the ball this year, trajectory calculation this year cannot ignore air resistance and it also cannot ignore back spin for those who are using a single wheel. Back spin make the ball travel higher and further.

If you ignore air resistance or back spin and try to correlate to real test data by scaling the exit velocity, it would be meaningless. Adding air rsistance to your calculation would be an improvement because you have the shape constant to tune but you are still ignoring an important factor which is the back spin. The back spin is significant especially when you are shooting from far away.

I will be posting my trajectory calculator (in Excel) on our website soon. You can look at the calculator for 2008 and 2010.

We have not done tuning yet. Our robot will not be done for another 2 weeks.
