Except that in the case of PINK and MOE it is the entire robot that is pink or green which means that it is much closer to the height of the vision target than just bumpers.

Re: Bad news for Pink, MOE, ThunderChickens ... ?

Rather than pick up pink or green, we decided to look for a pattern of pink over green (or the other way round) (so we can tell if it is a red or blue trailer, of course). If Pink or MOE get atop each other we may have a problem, but no pattern, no tracking, so colored bumpers should not be an issue for us.

That's exactly what we're doing, but some teams may just add a simpler tracking program at the last minute due to time constraints or programming ability. So, it could still be an issue for a lot of teams.

Re: Bad news for Pink, MOE, ThunderChickens ... ?

We noticed that MARS's red shirts were picked up as pink until we tweaked the settings a little bit.

Thankfully, our robots tend to be more black than red, but the red will be there.

It is up to the teams to focus on the correct targets, and also on the teams to change their robot color scheme if it conflicts with the swatches provided in the KOP. Do it for your alliance partners' benefit.

Shirts outside the playing field should not be an issue. Most cameras will be used for autonomous only, or should have an override if a problem develops in tele-op mode..
