At kickoff, it looked like they had an electronic sensor system that counted the balls as they passed through.

Re: counting balls

yes, and thats why there is a rule that your robot may not enter the goals with a 5 point penalty.

Re: counting balls

I guess that means we can expect a somewhat-instant on-screen scoring system this year? Excellent...

Re: counting balls

On the bottom goals, there is a strip 3 inches into the goal, which is triggered on each ball that passes over it. On the top, I'd imagine that there's a strip after it drops down into the chute.

Re: counting balls

Actually if you look in the image gallery here on CD you can see that the white strip is just a light strip and the real reader is up above that. Its a type of camera that can sense the balls traveling over the white strip.

(camera that sends data to a computer, and the computer counts? :my guess: )

Re: counting balls

So will scoring be instantaneous this year, or will we have to guess how much each team has at any point? It sounds like they have the ability to give real-time scores, but as they didn't do so last year, I'm wondering if that will be a change this year.

Re: counting balls

last year it appeared taht they had the scorekeepers entering the information in real time, but that introduced lag. This year the scoring is done by sensors and computers, so we should get a reasonably accurate score (i hope)

Re: counting balls

Yeah, I have heard that there are halogen lights under the acrylic, and when the balls pass through, the camera that is mounted on top of the alliance zone over the goal area. It is able to accuratly count the number of balls that pass through I would think because of the breaks in the light. But dont ask me.

Re: counting balls

Rumour has it (dez told me!) that it's essentially image recognition. The light just provides a point of refrence for the vision system, and it counts interruptions of that light. Rumour also has it that it can't count ten at a time

Re: counting balls

Well now comes the question of can you double score

I'm sure FIRST has already dealt with this issue but i have yet to hear what happens when a ball enters the goal on the floor (this would be the first time counted), Bounces out (2nd time counted) and then is pushed back in (3rd time counted). Because if it really is just a device that records when a plane is broken then FIRST is going to have to have refs watching the lower goals at all times.

Or am I missing something?

Agreed. 1293 bounced the ball around yesterday, and FIRST Frenzy balls they ain't. With that ramp in place, I doubt we'll be seeing double scoring.
