Final scoring time limit

In Rule G05, does “all objects in motion” … “come to rest” mean when balls and robots stop moving across the field, or would the motion of a robot arm of a stationary robot be counted as an object in motion?

Actually, I’m confused by G03, G04, and G05. G03 says the match “ends” when the timer reads zero, G04 give the points awarded at the “conclusion” of the match, and G05 says scoring happens up to 10 seconds after the timer reads zero.

Can the robot continue operating (autonomously) during those 10 seconds and earn points or not? Sorry, but I’m new to FRC …

I’m starting to think the only point of the 10 second extension is to lose points if you fall off the tower.


After the timer reaches 0 all robots (auto or teleop) must stop. The ten seconds says if a ball is rolling towards a goal but time runs out before it enters the goal that the ball has ten seconds to make it in. So if you do a long shot with 1 sec left it still will count since it will take over a sec to make it in. Hope this helps.

An question would be what would happen if a robot had a kinetic device meant to move in the final seconds of a game (ie. a mechanism that was designed to pull the robot up the tower) and the robot triggered this device as time hit 0. From my interpretation of the rules, this would be legal and counted as a score. See 2008’s line crossing rules at the end of the match to give a clue as to what possible interpretations may be.

At least in 2007, this was allowed. Teams had to lift robots (again) and some used compressed gas cylinders to do this. As long as they started before time ran out (and finished before 10? seconds) the lift counted. This may be one for Q & A, however, just to be sure if your team is considering this.

In the case of the lifting, how the rules are currently stated, as long as you are off the ground and at the specified elevation (or hanging onto an elevated/suspended robot) before the time restriction runs out, it will count. Obviously, said action must be triggered ahead of time as the field will effectively disable your controls (with the probable exception of the compressor if you’re really desparate).

The problem is that the refs have to verify that you are above the plane. They will wait until time runs out and then come out onto the field to see how high your bot is. If it can not maintain the lift for the 10 seconds. It might not count. Its not that hard to make the act of disabling the controls, trigger the final action. In fact you want to make sure that the opposite does not happen. Disabling the controls might trigger something that undoes your final action. In particular hanging from the tower. If you need power to keep hanging, them when they disable your controls you will probably fall.

I noticed something box-like atop the drivers stations on the ball return mechanism, does that count the balls? If so, that might be what this is for.

I was replying with respect to a pneumatic method as mentioned above. In this case, as long as you don’t have some ridiculous leak in your air lines, (in which case you shouldn’t have been allowed on the field?) you had the pressure to lift in the first place, and your solenoid has been triggered, it will remain in that position until given a different signal (it sends null IIRC).

Also, ignoring other objects, if you come to rest before the 10 seconds, they will check it before 10 seconds (rule says until things come to rest or 10 seconds after, whichever comes first). If you use a motor related method, it will stop driving the motor the moment the round ends.

Also the box is to count balls coming back in for the DOGMA stuff (in other words to make sure you are returning balls to the field).

Apparently there is a counter-type device, but it is used to verify that the ball is returned to the field within the 11 seconds allowed by <G17>. There is another counter in the end of the goal funnel that actually counts the points.

Hopefully these devices work better than the vision systems used in Aim High.
