Bumper rules clarification
We have waited until the last two days to create our bumpers... in years past, there has been a rules stating that the connections between the bumpers and the robot frame must be, at most, eight inches apart. This year, however, we could not find such a rule. We are wondering if anyone has an answer to our problem. Thanks!!!!!

Re: Bumper rules clarification
As long as there is no more than a 1/4" gap between the frame and the bumper backing, you may have more than 8" of "unsupported" bumper.
...unless I've totally misread the following rule and associated Figure. R26 BUMPERS must be supported by the structure/frame of the ROBOT (see Figure 4-9). To be considered supported, a minimum of ½ in. at each end of the BUMPER must be backed by the FRAME PERIMETER. Additionally, any gap between the backing material and the frame: A. must not be greater than ¼” deep, or B. not more than 8 in. wide |
Re: Bumper rules clarification
Clarifying question on "backed by" - must all (5") of bumper plywood be touching metal structural elements? Would a 1" rim be enough? In the diagrams, it doesn't seem like there are continuous metal pieces on the frame, and the frame perimeter is also defined by an upward projection).

There is also a 1/2" minimum on the corners. Once again that is linear and an area. As others have said: It to your advantage to make sure your bumpers are roboust. |
Re: Bumper rules clarification
There is no rule this year that mandates attachment points. The rule is what is behind the bumper.
In theory, you could have pillars every 8 inches to "back" the bumper, and have only one attachment point. It wouldn't be very robust, but that is the team's choice. |

R21g: must attach to the FRAME PERIMETER of the ROBOT with a rigid fastening system to form a tight, robust connection to the main structure/frame (e.g. not attached with hook-and-loop, tape, or tie-wraps). The attachment system must be designed to withstand vigorous game play. ... So not really a choice. |
