Re: Week 3 analysis

Also, defense isn't necessarily disrupting their cycle, it can be disrupting them from disrupting your cycle - especially if you know your cycle is faster or more points. 3548 was awesome at setting up a pick for us to get around and score.

Re: Week 3 analysis

My ideal alliance was created this week.
All 3 robots make autonomous in the high goal/2 make it with one as a 2 ball.

If your robot can only shoot from one place on the field by elims you are gonna have a bad time. I will know where that spot is and you wont be getting there.

Inbounder passes ball on the ground to midfielder,
Midfielder trusses it to HP or just to other side of field,
remaining robot scores high or low depending on defense.

When ball is not in your robot's possesion you better be able to play zone coverage defense or interference for your partners or against the opposing alliance.

If you miss your auto balls in elims and your opponent doesn't. You lost the match already and least there is a much higher chance of it..

I'm not a statistician, but this is what I found.

I looked at the results for all of the MAR and NE events (8 total) and found the sum of an alliance's Qualification Score, Assist Score, and Autonomous Score. I then ranked these by event from 1-8 (to standardize by event, 1 being highest, 8 being lowest). Alliances were also ranked by what order they picked.

For the winning alliances the averages were:
Pick rank: 3.5
QS rank: 2.625
Assist rank: 5.125
Auto rank: 3

These results make sense. The alliance with the highest total QS score wins most of the time. Out of these options the best predictor of an alliance winning in eliminations is how much they won in qualifications.

Obviously actual scouting would be better for picking than this.

The thought process for our pick list as far as shooting goes is limited to this:
1) can the team score in auton?
2) can the team score in case we're drawing strong double team defense? (In this case, we would change on the fly to let the other team score and we'd play assist. That usually confuses the other team for one or two easy cycles until they pick up on it.)
3) Can they do a truss pass?
4) Are they so good that we wouldn't want to play against them?

That's about it. All of our other pick-list criteria was centered around how well they inbound, pass, floor pick-up, defend, don't foul, etc.
If 4 is true, I would assume 1-3 must be true. Agree on all those points, although not the order. I don't place as high of a value on Auton because we have a 2 ball, so only one of my partners needs to have one.

In both picks, I'd require (hence the numbering):

1) Willing to cooperate with the agreed strategy. If you're getting in your partner's way, you're out. I don't care how cool your robot is.
1) Ball Handling - pick up, hold onto the ball, and able to dispose of the ball to their intended location. I do not want to waste 15 seconds of my cycle waiting for you to pick up the only ball while you are undefended, especially if you are just going to get rammed and have the ball fall out.
1) Ability to play defense - what else are they going to do while we're scoring? Drivetrains are more important than any previous year.
1) Does not get stupid penalties.

Wouldn't it be better to pass without touching the ground?

Don't discount their current regional win dude... At Palmetto 1024 figured out their strategy, but couldn't stop them in the 3rd match because 900 figured out how to play counter-defense. There was more to 900's strategy than just sit in a corner and shoot, even if it looked that way. Also, last time I checked, 254 sits in pretty much the same spot when they shoot, but defending against them in that spot is almost impossible.

I'm sure people said that to 469 back in 2010. Of course the game is different, the scenario is different, and 900 isn't nearly as lethal, but it contextualizes the ignorance of your statement.

There are enough teams that are only comfortable with shooting only from a small handful (1 or 2) spots on the field (read: 254, 1114, etc.), and I don't know a team that'd want to go toe to toe with them on a good day.

Re: Week 3 analysis

As a recent graduate and current mentor of Team 751, I would like to state that I was very surprised to read Dr. Bot's posts, and would like to make it clear that those opinions do not reflect the beliefs of our team as a whole. 115 and 1868 are actually two of the teams who we have spent the most time working with and who have helped us the most (at least over my five years with 751), and we hold them and their robots in very high esteem. I sincerely apologise to everyone who was (rightfully) offended by those posts.

Re: Week 3 analysis

Defense can shut down an entire team! Here is a video of us stopping an entire cycle where the team could have potentially scored atleast 3 more cycles!

I think we completely agree. I didn't emphasize it, but my that list of attributes was only as far as shooting the ball is concerned. To be honest, as long as they could score in autonomous, shooting the ball wasn't a huge deal for us other than as listed.

I know Lake Superior was a week 2 event, but I found that at that regional pushing defense was unbeatable because if a strong pushing bot got between the opposite alliance ball and the opposite alliance robot then they could just sit there pushing the other teams away from the ball. I also saw that pushing defense could disrupt shooting. In one instance I saw a team push another team that was just about to score back to the other end of the field before the offense bot was able to maneuver around the defending bot.

Re: Week 3 analysis

Hey Everyone,

I am very sorry, I've seemed to upset a lot of people, and I am trying to get my head around that. I certainly would never put down any team that comes to the competition. I once talked to Mark Leon when he was watching the Poofs win another regional, and I told him, "You must be very proud of your team." He replied "They are all my teams." I feel the same way. Maybe I would of been better off just to say passing is important and leave it at that. Instead I shot myself in the foot, reloaded and shot myself in the other foot. Well, at least I won't limp.

I want to especially apologize if MVRT, TKO and the Space Cookies, and the Apes feel I've put them down. You guys are all awesome and I expect great competition at SVR.

Elaborate. How many other ways of passing the ball between robots have there been. Beyond truss toss/catch & HP loading.

Challenge accepted.
I say passing on the ground is way more effective from inbounder to truss specialist with relentless defense on you.
