One point for coopertition bridge

In the rules, it states this:

Quote:

If a Robot from each Alliance is Balanced on the Coopertition Bridge when the final score for a Qualification Match is assessed per Rule [G37], each Alliance earns 2 Coopertition Points. If the Coopertition Bridge is not Balanced, but a Robot from each Alliance is fully supported by the Coopertition Bridge, each Alliance will earn 1 Coopertition Point.

[G37]

Final scores will be assessed 5 seconds after the Arena timer hits zero.
So, since the robots are disabled when the timer hits zero (causing robots to roll off of an unbalanced bridge), does that mean than a robot on the unbalanced bridge would have to have brakes to stay on the bridge (or some other means to stay on) for five more seconds after being disabled to get the one point on the coopertition bridge?

Re: One point for coopertition bridge

brakes, or pneumatic/spring loaded feet, or simply being turned sideways should be enough to keep from falling off.

Re: One point for coopertition bridge

Only time I saw this happen at the three events I have been too was when one bot was crooked on the bridge and jammed against the side rail.

Re: One point for coopertition bridge

I'm pretty sure our drive motor controllers are set to brake mode. We noticed the bot is much easier to push after we turn it off. There were a few matches where we were staying on an unbalanced bridge.

Re: One point for coopertition bridge

I know I saw a few in week 2 when watching the webcasts (WPI I think had at least once)

Just look at the standings for any odd numbers in CP

Re: One point for coopertition bridge

Another situation I've seen this occur is when a red robot was assisting in the balance.

I believe the exact situation was that a red robot and a blue robot were trying to cooperate, and the red robot needed a push, and so a second red robot helped move the stack. I don't remember the exact ending, but I do remember both alliances walked away with a point.

Re: One point for coopertition bridge

We did one at Alamo, sit and made sure we got one coop point for both supported robots (red/blue) by the end of 5 seconds after the match.

Re: One point for coopertition bridge

I know 1717 had their programming set up, where they could press a button, and all of their swerve modules turned perpendicular to the bridge. This was suppose to act like a brake, so that they could still get the 1 point. I'm pretty sure they never got to use this feature though.

Re: One point for coopertition bridge

2067 had a 1 CP round at WPI. I believe that it was with team 1100 (and looking at their QS it makes sense). We have a very high traction drive system (pneumatic tires), and, if I'm remembering correctly, we were turned slightly sideways so we didn't roll off as quickly.

1717 has an amazing robot. They can fly around the field picking up balls very quickly but also climb the bridge well. Their swerve modules have two speeds! They even go over the bump better than most robots. It is a very very impressive robot.

Yes their robots are always amazing. Their swerve was pretty equal with 973, as both had 2 speeds, and were independent, though I believe 973 was geared a little faster. Any swerve could have turned their modules perpendicular actually, though I specifically heard of 1717 programming it into their code for that purpose.

Re: One point for coopertition bridge

this rule is the main reason (besides helping balance the bridge)that my team decided to build simple brakes that always engage when the robot is disabled.

We've actually found that turning them into "spin" is more effective to prevent sliding, especially if someone is wedged against you. Perpendicular probably works in most cases though. YMMV.

"Spin" meaning:
