Good eye. Yeah, it'll be rectified through some combination of moving the spool back a bit and removing some material from the spool such that in one position, it's within the frame perimeter (and we'll start each match with the spool in that position). Even as it is on the practise bot, I'd call it a minor protrusion no greater than 1/4 in, but I'm not sure how many inspectors would agree.

Re: pic: 3322 First Design Iteration / Practise Bot

Looks like pliable roller 'fingers' can be pulled into the frame perimeter before start of match so should be legal.

Re: pic: 3322 First Design Iteration / Practise Bot

Nice - similar to our robot in general delivery, but we're not that far along, and we're leaving space for a floor pickup; our "gear holder" goes far enough back to accept a gear coming up from the floor, and tilts farther forward to push the gear onto the peg for a more secure position.

Re: pic: 3322 First Design Iteration / Practise Bot

I love this robot. It stays simple but should be very effective at what it's attempting to accomplish, and plus you finished super early so you have plenty of practice time. This is the robot a lot of FRC should have built, and they will be kicking themselves for not having gone in this direction.

Team 4272 is also going with a similar design of Gear loading and Gear manipulator on the other side. It seems like the most simple, yet efficient method.

Good Luck!!

It's interesting strategically, and we had many discussions about it. One bonus is that you can tweak your gear receiver without affecting your gear placer. The bigger point is that we think it'll skim time off our cycles because of the driving path. If you're one-sided, the best choice is to do a stop-and-go near the lift, which is very susceptible to defense. In this case, you do a sharp turn to line up with the nearest lift, or not so sharp and go to an alternative lift (altogether, should hold up better under defense).

It's funny, I feel like up to this point last season, we accomplished a similar amount of work. But we tried to do too much, and so we were nowhere. I'm feeling good about this year. Don't get me wrong, we're not nearly finished, so many tweaks to make and still a whole comp bot to build, but I'm just happy to have time for tweaking, testing, and practising.

As a member of the controls team on 3322, I am extremely excited to have a bot to test with at this point in the season. Gives us plenty of time to test automating driver actions.

Re: pic: 3322 First Design Iteration / Practise Bot

So why makes this design more efficient than a "cereal box" type of gear manipulator where the gear can be "stabbed" by the spring and barb and pulled up by the pilot?

Just playing devil's advocate here

You load from one side and drop off from the other side. As others have said in this thread, this makes you less susceptible to defense, as you don't have to stop and turn around to place your gear after running it across the field.

You don't have to wait for the human player to finish fishing the gear out before your robot drives away. This shaves a few seconds per cycle, which really adds up.

The low angle of the human load collecting mechanism also makes the loading faster and more reliable than other mechanisms.

I didn't realize how incredible of a design/strategy this is at first. You guys will have some of the most practiced drivers out there, which should do far more for you than any gear ground pickup, actuated peg drop, or moving gear placer that have been touted as "completely necessary" for a gear placing strategy here on CD. And... you skipped the fuel completely, which means (assuming better alliances will be able to get all 4 rotors going) you will likely be playing a little defense come eliminations, but your drivers will be up for the job.

Actually, we don't release the gear onto the peg. "A few seconds" is a gross exaggeration. Our testing suggested that, if your pilot is ready, you save a fraction of a second at most. And our pilot will be ready.

This is a big question. Given the depth/quality of district events, I don't anticipate any district elimination alliances consistently getting all four rotors going. Because if they can, opposing alliances will play just enough defense that they can't.

This was our line of thinking as well. Cycle time is going to be king in this game. We wanted the drivers to have to turn around as little as possible to shave time off our cycle and to make it harder to defend against. We also wanted our intake to be as robust as possible so that it would accept gears no matter how the human player puts it down the chute or what sits between us and the chute. So following the natural telemetry of the chute seemed like a no brainer when designing our mechanisms.

I completely agree about feeling like building within our means was the right choice to go with. Our practice robot is about 90% done and comp bot is about 40% done and I don't think we have ever been this on schedule before.

Re: pic: 3322 First Design Iteration / Practise Bot

Kudos for the foresight to recognize the potential power of extra drive time vs. going after other objectives. This solution probably has the most "Bang for the Buck", and finishing early to get the stick time will make it incredibly effective.
