pic: YMTC: Is 41 hanging?

Just look at all the pieces/flakes under the ramp from last year's stack attack game. So based on that rule above, I would either have to say, no robot can hang, or I could say that if it's a situation like team 41, I'd count them as hanging. So what if a piece falls off. But too late to change that now

If a molecule falls off then it's not part of the robot anymore and doesn't count.
In the picture, the belt is still on the robot and touching the platform, so they don't count.
"Don't be a lawyer", or something like that.

Something very similar happened in one of our matches actually, except it was with a chain and the refs called it a no hang. But it was a good call because if I remember correctly the rules state that if any part of your robot is touching.

I say no hang. They are touching. How would you feel if you were the other alliance and they counted. I don't think they deserved it because every other team had to build their robot to withstand hits and things breaking so that they would not be touching the platform.

Atleast all of the refs' decisions are uniform. Every example that has so far been given of similar incidents they were ruled as a no hang as well this one for 41. If half of those were counted and the other half were not then I would be cocerned, however, with all of the judges seeming to agree that it is a no hang, then that must be the rule and not up to interpretation.

Yea, that match really did suck. We sheared our left drive pully and we managed to get up and hang with only our right side operational. Cruel twist of fate. Luckily we got someone to the machine shop to make another timing pulley from some Al bar stock. In the meantime, we used the dremel to make new notches!
Thanks to whomever took that pic!

I say give them the hang because is that tread really supporting any weight. If they believed that it was then they should have taken the tread away and seen if the robot would have fallen. Its like sayin OMG there a little piece of string that is touching the platform and its supporting weight . They seriously should have been given the hang.

No, hang, as the rules state no part of the robot may be touching the ground. Though, if I was on 47 I probably would be feeling very different. Though the rules state it. I'm a little surprised at the ruling. The refs at the midwest regional seemed to be extremely leniant about hanging. I saw a couple of robots hanging on the very inner part of the connecction between the vertical and horizontal bar, which was ruled illegal in other regionals.

What if the belt was no longer attached to the robot in any way, but just lying on the platform. Then would you count them as hanging?

I would say, yes that would count as hanging. If the timing belt was lying on the carpet or on the platform, in no way attached or semi-attached to the robot, this hang would be counted. If portions of your robot unintentionally detach from your robot they are not considered parts of your robot anymore for the scoring of the match (like light covers from last year, etc.). But in this case, the tread is still in the robot and touching the 1’ tall step. Last year teams were deemed not on the HDPE platform because a string or zip-tie was touching the grating. To me this seems perfectly consistent with FIRST’s past interpretations / enforcements of rules.
