Vision target location
 

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

Re: Vision target location
 

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.

Re: Vision target location
 

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

Re: Vision target location
 

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

Re: Vision target location
 

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

Re: Vision target location
 

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)

Re: Vision target location
 

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.

Re: Vision target location
 

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.

EDIT: Fixed broken link.

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.

Re: Vision target location
 

I posted two questions to the q&a last week: q157 and q158.
Sorry for the excessive use of abbreviations, was struggling to stay within character limits.

I agree that there isn't enough information in the manual, any of the drawings, or the video to relate the targets to one another. Particularly in the horizontal dimension.

The video defines the vertical targets position relative to the "inside edge" of the low goal. Does that mean the face of the cube furthest from the field perimeter, or does it mean the edge of the opening in the cube through which you could score a ball. I interpreted the later, but others on my team disagree.

Also, are the measurements provided relative to the vision target's reflective material, or the black border which surrounds it? The game manual makes it sound like the black border is considered part of the target, so my hunch is the later, but this isn't an element of the field I want to approximate. I want it to be as accurately replicated as possible. This should be a relatively easy set of information for FIRST to provide, the game manual has all but one dimension defined already.

Re: Vision target location
 

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