How many Robots at the nationals had an operational Camera Track Autonomous?

[Greg McKaskle]

I never tried an additional IR filter. The lens from the mfgr has one built in. Do you have any before and after images, or values?

As for the polarizer, they are useful when the light is polarized, otherwise they are equivalent to a neutral density filter (a gray piece of glass). The atmosphere polarizes the sunlight to some degree, so polarizing outdoors is pretty effective for blocking glare more than other light. Indoor lighting is not polarized.

The wide angle lens helps with seeing more of the field without panning the camera. I saw some put lenses in front of the camera, others replaced the lens. If you replace it, beware to get an IR filter.

Anything else?
