Robot Access Period Questions

So, assuming your robot has an arm that is less than the withholding allowance, you take it off right before you bag your main robot on bag day. You attach it to your practice robot and work with it until your first event in week 2. In your time prior to unbagging your robot in the access period you remove it from your practice robot and verify it is still less than the whithholding allowance. You then proceed to unbag your robot, attach it to the primary robot, practice/do whatever, then bag it back up to go to competition.

This is also how I think it should run too. However, maybe I'm just blind, but I can't find the withholding allowance anywhere in the manual, and I can't find anything about limitations applied to the access period. It would be nice to know exactly what's ok and what isn't before we have to bag the bot.

It's also worth noting that for district access periods, R18 specifies 30lbs total between the access period and the event. That means you can't swap out a 20lb manipulator for an upgraded one during the access period and then also bring a spare of the new 20lb manipulator to the event (total of 40lbs). You could do that with a 15 lb manipulator and a spare (total of 30lbs).

My interpretation of the rules also allows for the team to put an upgraded 20lb manipulator on during the access period and bring the old 20lb one they took off as a spare at competition, since that was part of the original bagged robot. Someone can correct me if they think this is a misinterpretation, but since I believe the intent is to have the robot access period act like a regional Thursday, this makes sense to me.

What's interesting to me is the fact that we can add unlimited weight of fabricated items. When you're at a regional, your fabrication ability is fairly limited. At home, we can do spectacular things in 6 hours.

On my old team, we built the competition robot starting at the beginning of week six. Before that, it was all practice robot parts. Once we'd made the parts once, we could get the frame welded up in an hour. My current record (which is still the fastest, because we ran two CNC's at the same time) was 2 hours and 20 minutes to CNC, assemble, and mount two shifting gearboxes. Making the same parts two times in a row is much faster.

I think, that if we practiced, our full team of 50 or so kids and mentors could fabricate 90 out of the 120 lbs of robot in 6 hours no problem with some practice. So, if you know exactly what you need before your access period, and you've got your CNC machines/mills/lathes/welding team set up with the stock already clamped down, the drawings/toolpaths already made, and gave your team 6 hours, you could get a lot done.

Sec 5.6 is what you need to look at. Please note that you can unlock for shorter periods than 6 hours but nothing less than 2 hours and a total of six hours.

Just to clarify, you can physically close the bag earlier than 2 hours, but that access period must count for at least 2 hours of your total time (IE a 15 minute acces or 1:59 both count as 2 hours). This was different the very first year, but has been consistent since. This essentially limits teams to at most 3 unbag times. My experience is there is a pretty even mix of teams using 3 access periods, 2 access periods, or 1 access period.

Also, new to this year are "robot displays". Section 5.4.3. covers this new rule. The intent is to allow teams to do short displays of their robot to schools, sponsors, and ... but you are not allowed to work on the robot, or have extended acces times that might be construed as practice.
