Ease of Viewing Game Pieces on Field?

[engunneer]

The two things I have to add to this are:

- Remember that the robot camera is allowed to be fed back to the driver station this year (as best as I can tell)

- Notice that the center field stripe is the same white/black/white pattern as the goal vision targets, and it goes through the tunnels.

I think they are encouraging us to use the camera for driver assistance, and a good team will use the vision system to steer the robot through the tunnel.

Even easier than using the vision system for the tunnel though... get a small photodetector and an LED or two, and mount them on the bottom middle of the robot. You *should* then be able to detect when the photodetector can "see" the white line when compared to the carpet, and a little semi-autonomous programming can keep you running straight down that line. Plus a nice bonus from getting this working - you can work the detection into your autonomous program so you never violate <G28> and get a penalty for completely crossing the line during autonomous!

Last year, my team had a turreting shooter, and we used the camera to automatically aim it at the opposing trailers. When we were in range, an LED would light up on the drivers' station. The driver could then fire with a good chance of scoring. It worked great once we got the shooter to work right. I feel that the same method could easily be applied to the vision targets in this year's game.

well accualy, we started with a "lazy susan" turret, but scraped it for a fixed shooter

The vision targets are not the issue, as they can be seen from anywhere. The real issue is seeing the soccer balls on the floor behind the bumps.

I was going to post to condradict you saying we need some way with the camera to see the balls...but what's worse is if you are a scoring bot, and you score in the opposite goal of where you and your team are positioned in the alliance station (and it might be hard also to see form the middle...maybe less), there seems to be some sort of wall there too, based on footage of teams showing the offical field in NH. It'll be hard for the drivers, just from looking to the side and trying to understand thier perspective vs. robot perspective of what is the roobts position relative to that wall (Bumping into that wall when try to score will suck :-/ ).

I would like live vid footage, but as some of my team members have said this year, like last year, the bandwitch in the field is not capable of withstanding soo large of communication data between robots, the field and the driver station of each team. Even if a team WOULD do so, it would cause some delays in the field system.

But if FIRST has been able to solve this issue somehow, oh, how I wish I was one year younger than I am right now.
