New Custom Feature: Ball Trajectory

This looks fun. Now just add in temperature and humidity and wind speed/direction. 😁 Maybe toss in if the ball has a seams (baseball fan here. haha)
coriolis too?
🚽 nah, not really applicable for me. 😂 What prompted you to create that for onshape?
robot competitions often have ball shooting
This is an interesting trajectory.
it does weird things as you get further from "typical" cases. you have a huge light ball with backspin.
This is very interesting . . . as a competitor in FIRST myself, I will look into this, nice work!
Not sure how accurate this would be in real life, but it seems like it would be good for prototyping, as you can get a rough idea of the specs your design should have before you build it. The only thing I can think of is if the ball has holes, like a wiffle ball (or like FRC Steamworks / FTC Velocity Vortex), then the air flow and overall ball path would be different.
:)
i think just changing the drag coeff and size and weight could help for that. lmk if you need changes to the FS. season is coming soon.
Wow, I would have never thought to do this with FS. Really cool to see!

thanks you @EvanReese ! There's so many calculators for robot stuff for FIRST competitions, I just like having them in Onshape to create usable geometry. GPT actually wrote the big function to make the point array from input variables. it's gotten way better now that gpt5 is out.
