Physics Calculations for the Climb and the Outer Port

[HFocus]

Hey Everyone,

I’ve been working on a few calculators in Desmos to help our team with design and prototyping. One can be used to play with the placements of robots on the switch to determine what would balance the switch. The other two are for Shooting balls into the Outer Port, and calculate needed velocity, vertical angle, and horizontal angle needed to make the shot, along with calculating error margins for all three.

I’m dropping these here for any other team who want to make use of them. The instructions for using each calculator are included with each graph.

And here is the stuff for the Horizontal Error:

Nice. We have people working on this too. Any thought of adding drag coefficient and Magnus effect?

I’m guessing that the purple & grey lines represent the inner target and the depth of the chamber behind the opening.

Is there a way to change the release height of the shooter?

Based on the comments in the calculations, you’ll need to adjust the relative height of the goal from your shooter. 98.25" is height from the ground. If your shooter is 20" above the ground, change the target height to 78.25".
