Trajectory Calculators and the “Sweet Spot” Parabola
For those of you that weren’t involved in FRC back in 2014, you may not be aware that Aren Hill, a friend of Spectrum, “invented parabolas.” During VEX’s Build Blitz that season Aren detailed a method of deciding on your shot trajectory by defining a wide “sweet spot”. The same principle should work this year.
During tonight’s meeting we did some analysis using two tools published on chiefdelphi to calculate the trajectory of the ball from a shooter. Thanks to CMarley, and Sam Geckler for posting these calculators.
Basic idea, have the top of your arc at the top of the goal and a long flat tail on each side of the apex that still allows your ball to go into the goal.
