Bumper zone clarification
 

I know this has probably been asked in previous years, but could someone clarify G23 for me? If a robot is climbing in such way that it is parallel to the floor, would it be violating this rule? (The only example given is with the robot being at an angle).

Also, if the entire robot were lifted somehow (for example, if it were to end up on top of another robot), would it be violating this rule? Or would the "base" of the robot be transposed to a flat floor, making it legal (except for the whole on top of a robot part). The only example given is with purely the bumpers being lifted without moving the entire robot.

parallel to the floor just means your robot is at an angle of 0. this is fine.(updated)
I don't think you'd be violating this rule, but it violates others. G14 specifically.

Re: Bumper zone clarification
 

Not sure what you mean, G23 is a rule that limits shooting fuel only to your launchpad. It has nothing to do with climbing.

Re: Bumper zone clarification
 

I'm not sure how G23 applies to the situations you're describing. I assume you meant to put R23.

None of the situations you described would violate R23. The "floor" in this rule is relative to the robot, so basically the floor is the plane defined by your wheels if your wheels is what would be the lowest points of the robot when sitting on the floor.

Thanks, and sorry for saying G23 instead of R23.

I can only assume this rule was added because of this incident.

Re: Bumper zone clarification
 

For those who weren't around when this happened, can you give a backstory to this??

816 and 87 both wanted to cross the same defense and couldn't cross any others. No rule about robots needing to start on the ground. The plan was for 816 to drive forward, cross with 87 on its back, and both of them would get crossing points (because both of their bumpers started fully in the neutral zone and ended in the courtyard). IIRC they didn't make it all the way across but both got reaching points.

Mentos,
To insure everyone understands this, under R23 the Bumper Zone is determined during inspection when the robot is standing on the floor. The bumper zone does not change if the robot changes attitude during the climb.
It is meant to address those teams who want to actually manipulate their bumpers so that they move from the fixed position.

R23. BUMPERS must be located entirely within the BUMPER ZONE, which is the volume contained between the floor and a virtual horizontal plane 7 in. (~17 cm) above the floor in reference to the ROBOT standing normally on a flat floor.

Re: Bumper zone clarification
 

OK. Our robot, including bumpers, is 36 x 40 x 24 tall. When we climb, our robot will be tilted at an angle. while tilted, if someone were to take a horizontal measuremenet along the length of one of the longer sides, a measurement of 40.311 inches would be found - this is also equal to a kitty corner measurement of a long side bumper at rest while the robot is sitting on the ground floor. So are we in violation of the bumper zone rule during the climb or not? Confusing especially when I take into account the Q and A answer to Question 151, where they use the phrase 'transposed on the floor'. Not sure what it all means.....

Re: Bumper zone clarification
 

You're tilted, but what happens if you suddenly land level on the floor?

Right, you're back to your starting size. Note the exceptions for robots tilting while climbing ropes, etc.


You'd be neither in violation of the volume nor in violation of the bumper zone, UNLESS there's something you aren't telling us that would change that answer (stuff sticking out, for example).
