Wouldn't lifting the robot violate the bumper height rule?

Depends on how high you lift the chassis.

Also, you'd need to be careful of 'articulating' bumpers.

Bumpers may not be articulated.

Exactly why I mentioned it

May our 14" mechanism expand in the bumper zone outside the robot?

I would assume so. My POV regarding this is that the bumper zone is only a bumper zone when there are bumpers present. That sounds a bit confusing, but what I'm saying is, you have your bumpers set with the openings, then you have an arm(or whatever) at the same level as your bumpers, then yes, its seems like you can expand there(if that's what you're asking)

What is the bumper height restriction this year. I see nothing in the specs.

R01, blue box


[R01] see the whole rule as trimmed for content......... The Frame Perimeter of a Robot is defined by the outer-most set of exterior verticies on the Robot that are within the Bumper Zone, which is between 2 and 10 in. from the floor. Minor protrusions no greater than ¼ in. such as bolt heads, fastener ends, and rivets are not considered part of the Frame Perimeter.

To determine the Frame Perimeter, wrap a piece of string around the Robot at the level described in [R02]. The string describes this polygon.

Note: to permit a simplified definition of the Frame Perimeter and encourage a tight, robust connection between the Bumpers and the Frame Perimeter, minor protrusions such as bolt heads, fastener ends, rivets, etc are excluded from the determination of the Frame Perimeter.


Why this isn't in the bumper section i'll never know.

EDIT: Howdy neighbor! :-)

I don't think so -- any more than driving across a tilted ramp would violate the bumper height rule. The bumper height is clearly relative to the robot, and not to the absolute plane of the court floor, else any ramp action is inherently illegal.
