Vision target location

[goofy173]

For the vertical vision target. How far is it from the left edge of the poly goal assembly to the left edge of the vision target? (or right, doesn't matter)

I don't see numbers on the field prints

It's actually measured from the low goal. I don't remember the number but it is in the VISION TARGETS part of the rules.

Went thru the rules, watched the video, many times. No indication of what that exact measurement is.

I don't have time to check the drawings now, but there must be a measurement for the width of that piece of polycarb right? The center of the vision target is behind the edge of that polycarb so if you want the measurement to the edge subtract two inches.

Check out the CAD of the field. You should be able to get any measurement you want

Have you verified this? We too have gone through all of the manuals and videos.

In all cases we have not found clear cut definitions of the measurements to the locations of the vision target.

and how the horizontal and vertical target relate too each other.

If you have clear cut definitions please post them for all.

It would be nice if the center locations of each vision target was defined to say, the center of the goal wall

There is a question on this on the FIRST Q/A

I'm referring to the actual CAD model of the field. Autodesk has an Inventor Assembly for it (which you can also open in Solidworks)

Just some warning, I would be wary of using the FRC CAD models as definitive measurements. I know last year the Field CAD model was messed up with the complex pyramid and all. I'd anticipate that it would be better this year, but ya never know.

[goofy173]

I will have one of our CAD guys take a look, but I'm pretty sure he already did.

Watch the video, http://www.youtube.com/watch?v=8-vZmd3Vu9g&list=PLZT9pIgNOV6bScUlOhxxejG_rqTbhru_5& feature=c4-overview-vl and pay close attention to the commentary between 35 seconds and 1 minute. All the details are there.

I think you can get the dimensions from this:
There are four (4) VISION TARGETS on each end of the FIELD: two (2) dynamic VISION TARGETS and two (2) static
VISION TARGETS. There is one (1) dynamic VISION TARGET located above each LOW GOAL. Each dynamic
VISION TARGET is located behind the polycarbonate panel on the ALLIANCE WALL. The dynamic VISION TARGET
is horizontal and begins 5 ft. 8 in. above the FIELD carpet, is centered over the LOW GOAL, and consists of a panel
with one (1) 4 in. wide, 1 ft. 11 ½ in. long strip of retro-reflective material (3M 8830 Silver Marking Film) adhered
horizontally along the length of the panel with a 2 in. black ABS plastic border surrounding the retro-reflective material.
The dynamic VISION TARGET is actuated to show the retro-reflective material when its corresponding HIGH and LOW
GOAL are HOT. It will rotate to hide the retro-reflective material (pointing it upwards) when its corresponding HIGH and
LOW GOAL are not HOT. Both of these conditions are shown in Figure 2-9.
The static VISION TARGET is mounted such that half is behind the polycarbonate sheet above the LOW GOAL and
half is behind the acrylic panel of the PLAYER STATION. It uses vertical reflectors which are located above the inside
edge of the LOW GOAL. The vertical reflector consists of a 4 in. wide, 2 ft. 8 in. tall stripe of retro-reflective material
bordered by 2 in. wide black gaffers tape on the left and right sides. The vertical reflectors begin 3 ft. 1 ½ in. above the
FIELD carpet.

From that information, what is the horizontal distance between the two targets? And is that inclusive of the black border surrounding the reflective material?

There should be enough at least for the horizontal strip.
The horizontal one "begins 5 ft. 8 in. above the FIELD carpet, is centered over the LOW GOAL, and consists of a panel with one (1) 4 in. wide, 1 ft. 11 ½ in. long strip of retro-reflective material (3M 8830 Silver Marking Film) adhered
horizontally"

This tells you that it is centered above the 2 ft. 8 1/2 in low goal, which is placed in the very corner of the field (its outside edge is in line with the outside edge of the alliance station). Centering a 1 ft 11 1/2 in piece of tape over that low goal would then require you to be .375 ft from the wall (subtract the width of the tape from the width of the goal then divide by two). This translates to 4.5 in from the edge of the alliance station where the high goals are mounted and 5 ft 8 in above the ground, as stated in the manual.

As to the vertically oriented static vision target:
"The static VISION TARGET is mounted such that half is behind the polycarbonate sheet above the LOW GOAL and half is behind the acrylic panel of the PLAYER STATION. It uses vertical reflectors which are located above the inside edge of the LOW GOAL. The vertical reflector consists of a 4 in. wide, 2 ft. 8 in. tall stripe of retro-reflective material bordered by 2 in. wide black gaffers tape on the left and right sides. The vertical reflectors begin 3 ft. 1 ½ in. above the FIELD carpet."

The way I interpret this while looking at the picture is that the center of that reflective tape should be at the inside edge of the low goal. To double check it though you could see what the measurement is from the edge of the alliance station to the start of the acrylic since it states that it is mounted such that half of it is on the polycarb above the low goal and half of it is on the acrylic in front of the drivers.
