Hi, I was wondering how strict the judges are in the inspection. Our robot exceeds 0.5 inches of the frame perimeter at the longest point of the path of our intake (it is only part of the path, at no time the robot will remain in that position). I would like to know if we would pass the inspection or if we would have to make any modifications.
Are you talking about the frame perimeter or the extend limit?

If you are talking about frame perimeter, you are allowed to exceed the frame perimeter by as much 12in, so long as you are starting the match with everything inside your frame perimeter. However, if you mean your intake goes 0.5" outside the 12" extension limit, then that is considered against the rules.

if you are talking about frame parimiter they check it really well, if you are talking about the extend limit, they are much less strict (at least in Israel). don’t matter where are you it depends on the inspector you get, some of them are really nice and don’t care as much, and others are really strict.
Even a momentary extension past the 12” extension limit is a rule violation. I would recommend fixing it before your event.

I would encourage your team to get this corrected before competition. You’ve put a lot of work into the season, and “maybe they won’t notice” is not a great plan. In my experience, if it must be 12" or less, 12.5" isn’t going to pass.
As an RI, I would definitely bring in the LRI on something like this, and we’d measure a couple of times to make sure, but its a black and white rule.

Note the blue box under Rule 105: “Teams should expect to have to demonstrate a ROBOT’S ability to constrain itself per above during inspection. Constraints may be implemented with either hardware or software.”
So, it is possible to have a robot mechanism that CAN physically extend beyond the limit, but is limited (in software) from doing so.
Dazzy, if I am understanding you correctly, you have a mechanism that extends past the 12” extension limit by 0.46” and you are asking if this is a violation of R105. If I am misunderstanding please let me know.
Since R105 specifies a 12” extension limit and you are aware that your mechanism will exceed this by 0.46” then you will be knowingly in violation of R105 and I would encourage you to remedy this before you get to competition. You are essentially saying “We know we are violating R105 but do you think we can get away with it?”. The R105 extension limit is a design constraint placed on teams by the GDC. Knowingly violating this rule would be exploiting for a competitive advantage.
Your inspection staff should be checking for extension violations and if it is even close to 12” they should be double checking closely. There are different procedures for verifying. Some may use a large square as an aid. I like to find a vertical wall or something and have the team extend the mechanism to its maximum extent and push up to the wall and measure from the wall to the frame perimeter. If is really close and a judgement call needs to be made, the LRI should be included in the discussion.
As has been noted, there exists the possibility that a mechanism is mechanically capable of exceeding the extension limits but is software limited so that it is physically never allowed to violate R105 which is perfectly legal.
