Yet another bumper question

[FRC1828]

Is it permissible to have non-standard bumpers on a robot, as long as the required 2/3 of the perimeter is covered by standard bumpers?

For instance, our robot is currently protected on 3 of its 4 sides by bumpers. With our design, this comes to 71% protected, which is actually more than the required 66%. However, we also wish to protect certain components on the back of our robot. We would ordinarily use the standard bumper design for this, but, due to design constraints, we are unable to fit two stacked tubes in that space.

Would we be allowed to use a non-standard, 1-tube-thick bumper section, as long as it followed the same basic principles as the standard bumpers, and the required amount of the perimeter used the standard bumper design?

[GDC]

As long as a minimum of 2/3 of the perimeter of the Robot is protected by Standard Bumpers, then you have satisfied the requirements of Rule <R08>. If you wish to include additional bumpers of your own design on your robot, that is permitted. Note that any additional custom bumpers must fit within the volume and weight constraints defined in Rule <R11> - they are not covered by the exceptions provided in Rule <R13>.
