Re: Angle Calculation from image of goal

Re: Severe voltage drop
From the photo, it could be that your track width (https://www.google.com/search?q=vehicle+track+width&oq=vehicle+track+width) is too narrow. 6 volts when turning is ridiculous, but 9 when driving...

Re: Pointcloud PCD of Stronghold Tower?
I would be shocked if someone had a point cloud already. Perhaps getting vertices from a mesh file is enough? I'm not sure if you're acquainted with CAD tools, but here's a STEP model of the field on...

Re: FRC pocketing
It's probably because 148 isn't cheap or lazy :rolleyes:
One simple alternative: use thinner material without pocketing. I've seen a lot of pocketed designs in FRC that could have been made simpler...

Re: pic: Wood Coast Drive V2
Looking good, Cal!
