At least there are proofs to back up parts of GANs now. Modern machine learning continues to dig deeper into its empirical hole with GANs and neural architecture search*. Most of modern ML is engineering and trial and error. It isn't an exact science.

We really just want more blue boxes in the manual.

A worthy goal. Personally, I'm working on a betavoltaic-powered realtime clock for the RIO. I'd love to be the reason a "no radioisotopes" rule gets added.

Operator console says "go win the match, we'll check back in a few".

Re: Most Accurate form of Localization.

On the topic of the camera pointed down, What if you literally had like 4 optical mice on suspension to give a constant contact on the field, one mounted on each corner. Could you get useful data off of that? Why write your own motion tracking algorithm when mice manufacturers have written it already?

Relevant PDF: http://cdn.intechopen.com/pdfs/47040.pdf

However, it's not very relevant to FRC. The issue is that optical mouse usually have maximum velocity measurement capability of less than 1 meter/sec, and will be highly likely to have issues tracking a regular surface like carpet at speeds anywhere close to that.

A simpler form of this was done by poofs this year with their scale height detection.

Camera on driverstation fed their auto scale height to aim elevator optimally.
