I'm not sure why you wouldn't expect FIRST to fix the field... they've fixed the field in the past when the field elements were causing issues that weren't a part of the intent of the field design. In 2012, they redid the pieces under the bridge so the balls would roll out more easily. In 2013, they added a piece to connect the chains so frisbees bounced out less. This tuesday's team update will be huge, and I'm looking forward to what FIRST has to say about what went right and what went wrong.

You could argue that it was "consequential" because he fell out while diving to deflect his alliance's ball back into the field, so he gained an advantage while performing the action that caused him to end up out of the zone.

Typically, after welding, the properties near the weld are those of 6061-O, a loss of strength of around 80%. The material can be re-heat-treated to restore -T4 or -T6 temper for the whole piece. After welding, the material can naturally age and restore some of its strength as well. Nevertheless, the Alcoa Structural Handbook recommends the design strength of the material adjacent to the weld to be taken as 11,000 psi without proper heat treatment after the weld."

That compares to 35ksi yield strength of properly heat treated 6061-T6.

Teams that use welded aluminum construction need to realize that your welded joints are now incredibly weak. And that's if the welding has been done with perfect technique (certified welder with years of experience). High school grade workmanship will be way worse.

Been there, seen that a million times (after welding of that particular frame joint in your pic...It certainly appears to me that much more than 50% of the weld was then quite overly ground away, seeing that the appearance of the lack of any weld bead is also present). It is a ton of work I know, and the same issues happened to our team during Rebound Rumble (we played in the finals, lost, then rebagged a known very injured bot after our first regional, and it saw us stripping our bot completely down in the pits, to a very custom and powder coated dual side intake frame, at our second regional in Las Vegas, because every single weld broke that there was to break, between (many slightly over ground welds), a lot of very active defense, and that nasty floor beam we crossed much too often. That of course, led to many other bugs after the welding was done too, and that robot reassembled in a short period of time. That bot just wasn't quite right until Q time was nearly finished (it was by then, but we had not shown the necessary reliability to that point that another team would/could trust)....Wasn't a good year for us needless to say. I hope you fare much better in your case.

Not a weld on this years bot BTW, as we knew it was going to be a very defensive hard hitting game. Though last years bot was for us.....It lasted. (And that one incident caused us to learn to go much more modular in the future).

You have one thing going for you...At least the carry in has luckily been increased to 45 lbs....That 50% increase should get you there. (Well that and a good pit crew I certainly hope!)

Good Luck! (Weld clean, and leave the beads please).

Ummm...Yeah Jim...Just a little closer ...That could be the easy solution. Almost every shot I saw bounce back in, was much longer than it actually needed to be. And those not willing to change can always push it into the low goal.

Ok, for the ref's I might think a change is necessary (but still, to every bot choosing to be shooting the high goal). We are supposed to design to the field. Not the GDC changing the field to our design choices.

See you in just a couple of weeks...Can't wait after watching all this exciting week 1 action. Tough game for all!

I too would like to see pictures. That robot looks a little familiar.....

Do you remember team 1771's bot from 2008? We found their bot inspiring!

I would hope that he remembers 1771's robot from 2008 seeing that he was a mentor for the team that year

Here is a picture of this year's bot at Palmetto:

Hence the reason the bot looked familiar

Ahhh - cool!

Martin - we love your robot from 2008!. It was certainly a major inspiration to our bot!!!

I saw a lot of defense on the opponent's in the in-bounding zone. Several times, BLUEBALL got trapped between the REDBOT and the REDLOWGOAL while the BLUEBOT is hoping to get the first ASSIST.

More than a few times, REDBOT pushed the BLUEBALL into REDLOWGOAL or BLUEBOT pushed REDBOT into BLUEBALL and the BALL inadvertently traveled into REDLOWGOAL as a result.

It took a fair amount of time to return BLUEBALL to Blue HUMAN PLAYER and then to the FIELD.

I wonder: Will we see this called as a G11 or G12?

I haven't read through this whole thread yet since I am on mobile but I was thinking to myseld. If you have a 1 ball auton and neither of your partners has one, would it be worth it to still put all 3 balls on the field? You score your one and IF you have a decently fast pickup and scoring device then to me it makes sense to keep them out to get those quick 20 points before start the cycle. Mainly thought this because if your partners don't have an auto at all, you might be running and gunning by yourself and those points will be key as proven so far.

Its not worth it because you have to get those 2 balls and, if i'm on the other alliance, im going to do my best to send at least 1 bot at you and stop you from getting those 2 in so you can't get any assist, truss, or catch points...

For later on I agree but after watching the level of some of these drivers...I wouldn't be confident they could honestly stop a decent bot. Not speaking for just our team. I believe that will be the case for almost all events after week 3 but prior to that I think it might be a viable strategy

Do you have an opinion about webstreaming at Inland Empire? Our team ran that one, and we're hoping to run it at UCD.
