Ball Bounces Lands on Top of the Truss

The rule explicitly says that if the head ref shakes the truss, it won't count as scoring the truss points.

If a BALL becomes stuck on the TRUSS, the Head Referee will shake the TRUSS to free the BALL. In this situation, the ALLIANCE will not earn TRUSS points.

I don't recall seeing any questions about it on the Referee test, though…

As far as i remember there were two or three of these incidents at the Escanaba competition, it was pretty entertaining to see and not too big of a problem for the ref to shake down.

That seems really lame to me because they probably didn't put much thought in a rule (which is okay in hindsight because this will probably happen at the most like 1 time at a regional). I don't see why the alliance shouldn't get truss points, they had to get the ball up there somehow.

Is it so hard to give that panel a 5 deg angle?

You earn a truss score for getting you ball to pass through the plane. If you only got it up enough to get stuck and halfway through the plane, you didn't quite complete the task

Plus, the ROBOT is not causing it to finish moving through the plane.

Can you say end game?

In our situation, the ball did not get up there in an attempt to score over the truss, it got up there after a rebound off of the goal. Also, you cannot know for sure which side it will fall off of the truss. If it falls the right way once and that alliance receives truss points, then later another alliance does not receive points because it falls backwards, it is not fair to the alliance where it falls backwards. I would much rather have the ball back on the field in a timely fashion than worry about getting the truss points.

These are rented trusses. They are standard fabricated trusses that are used for audio/visual equipment. FIRST does not own them, nor do they build them.

Whups, you're correct. Shame on me.

Rotate them 45 degrees then.

The field would be out of spec.

Then bots might hit the truss, or balls might not make it over.

edge cases, I know, but that kind of change would make an angry riot

I witnessed the Arizona regional occurrence of this. It was rather amusing. They shook the heck out of it.

An elegant solution would be to place a single pipe lengthwise along the center of the top of the truss. It could be zip-tied in place, as it would not be subjected to much force. The trouble is that this would change the height of the truss, so it's not feasible to do at this late date.
