Your robot looks better than ours, at this point...

However, your appendage looks illegal, as it appears to be two appendages when it first crosses the frame perimeter. That's a no-no, according to the GDC Q&A on 2012-02-01

Q: Our question is similar to FRC1540. We want to put surgical tubing "whips" on a roller located at the frame perimeter. When this rotates the whips will extend beyond the frame perimeter. Is each "whip" its own apendage or is the assembly considered one appendage?

A: If multiple items exit the Frame Perimeter and are not contiguous outside the Frame Perimeter, they are considered multiple appendages.

When the appendage fully extends, they are connected outside of the frame

Re: pic: FRC 1086 Final Robot: 2012

Looks like angles on the chassis to traverse the barrier, what about the turret? Do you plan on rotating it or fixing it and using the drive train to rotate it? Did you guys ever get your cRio problems figured out last year? It was a shame to see such a nice looking bot with so much bad luck.

You guys know how hard it is to powder coat wood, right?

I was expecting something in the vein of your 2009 robot. Looks like this one won't disappoint either

Re: pic: FRC 1086 Final Robot: 2012

Therein lies the problem. When the appendage fully extends, it's good. While it is in the process of extending, at least looking at current Q&A interpretations, it's 2 appendages, and you're only allowed 1. There is more discussion at http://www.chiefdelphi.com/forums/sh...d.php?t=100696.

Re: pic: FRC 1086 Final Robot: 2012

We actually just talked about this issue at lunch today; we are planning on posting on the Q & A a question about if that instance where the rod that connects the two is behind the bumper but everything else is outside the bumpers will be forgiven. If not, we'll work on re-drawing the part so it is within the rules.

There are angles on the real chassis, the one in the top right corner, for bump traversing with ease. It is a design that we modified from our 2010 robot. We are planning, after many long design and strategy discussions, on not having a turret this year. Pinpointing the issue with our cRio was an issue but we completely replaced everything between the code and the robot. So we have a new computer to download code from (including code in a different language from last year), ethernet tether, bridge, power converter, and cRio (4 slot). Last year was rough robot wise but it certainly wasn't all bad luck that kept the robot stagnant.

Two points for Eric! Anything else you notice?

We have a little twist on our shooter this year. (no pun intended)

03-02-2012 23:36

EricH

Re: pic: FRC 1086 Final Robot: 2012

Yeah, you're bluffing about not having wheels. The shooter base has 4 (not counting shooter wheels), which don't look like they're powered yet, and that other chassis I mentioned is levitating (or has some form of wheels on it).

Re: pic: FRC 1086 Final Robot: 2012

Re: pic: FRC 1086 Final Robot: 2012

we are sticking to our interpretation that what we have is legal. The connection between our two "halves" is outside the frame and therefore legal. I think some CD members are "over thinking the question" as I warn my Physics students...

Re: pic: FRC 1086 Final Robot: 2012

Well, prepare to fail inspection. Q&A has pretty much said the opposite of what you assume.
(I don't like or agree with it, but if the GDC says it, it must be so.)

04-02-2012 02:04

wilsonmw04

Re: pic: FRC 1086 Final Robot: 2012

not to turn this into a copy of another tread, but this object is "continuous." Not sure where the GDC has said this is illegal. We will find out week 1 won't we?

04-02-2012 03:35

EricH

Re: pic: FRC 1086 Final Robot: 2012

Continuous outside the frame perimeter is key here. There will be a time during deployment, as shown in the picture, that the appendage will not be continuous outside the frame perimeter, and may therefore be defined as two appendages, which makes the entire appendage design illegal.

The million-robot question is, will the GDC add an exception for deployment before or after Week 1? (And, more to the point, are we going to see another "tape measure rule"?)

Re: pic: FRC 1086 Final Robot: 2012

Some observations from what i see...As mentioned the competiton robot
is in the background sans shooter and conveyor. It appears to be six wheel drive
with nylon wheels on one end. The ends of the frame appear to be beveled to
help the robot go over the barriers. On the practice/prototype robot the
conveyor is angled and driven by a window motor. It seems to be in line
with the shooter and gives the impression that some sort of turret will be used.
The shooter itself appears to be chain driven (No. 25 chain?) with 8" wheels.
The top of the shooter wheel appears to be about 50" off the floor. In the front
is a arm for pushing down the bridge and what appears to be another arm
that may be connected to the other one. This not only could be used to
push the bridge down, but also be used in conjuction with the beveled
frame to get over the barrier. It could also be used to right the robot if it
is tipped over forward if most of the weight is below the arms.
It appear the electronics will go low on the frame under the conveyor.
I would guess four CIMs will be used for the main drive and some
sort of cim-cim or cimulator set up will be used for the shooter.

Interesting robot. 2106 begins build today on ours. Can't wait to start making the basic frame. XD Perhaps we will make it turn on, we're not sure yet. All we know is it will consist of at least 5 pounds of metal, however any more that is still up for grabs atm. (Sadly, as much as I want to say I am joking, I am not, we are indeed BEGINNING build right about now.)

That looks like a lot of fun! If I recall correctly, there are actually a few teams that use this as their sole method of tipping down the bridge...

We've been busy improving our harvester and shooter, writing more auto programs, and getting more drive practice - I just wish I could make the trip down with the team! It'd be great to see you guys again!

We did that while practicing....but you might find it acts differently with the
bumpers on. If you try it..be careful not to flip it. It could happen.

Re: pic: FRC 1086 Final Robot: 2012

I think it was 435? maybe 422 I forget who was rockin' and rollin' to get on the bridge.

We did it with bumpers on later. We can't flip the thing over. We tried!

Re: pic: FRC 1086 Final Robot: 2012

539 had an appendage come out from the bottom for a controlled wheelie, I believe. Our driver just kinda... pulled it off in a match. As a coach who gets emotionally involved in a match sometimes, I nearly passed out when I saw Jack just pick up the front half of the robot with the joysticks and just throw it on the bridge.

Re: pic: FRC 1086 Final Robot: 2012

Might be a good way to get over the barrier also...might be a bit hard
on the electronics though. We had Jags in ours at first but killed two of them
going over the barrier and changed them to the tougher Victors.

I'll be volunteering at NC so maybe I'll get to see you all do it.

Re: pic: FRC 1086 Final Robot: 2012

the range of shot is good. Shots are consistent. having a problem with oscillation with our PID loop. keep shots are set for 2300 RPM but the fly wheel is moving +/- 200 RPM of target. Guessing we need to up the "I"?

02-04-2012 23:55

Nathan Streeter

Re: pic: FRC 1086 Final Robot: 2012

Yeah, we've been amazed how much small changes in shooter wheel speed and hood angle matter...

My background is primarily mechanical, so I may be providing misinformation... I'll ask one of our software guys about this; however, if I recall correctly our PID loops are primarily "P" and "D." They at least used to often have little or no "I." If I recall correctly hunting is a sign of the "D" not being turned up high enough (and/or the "P" being turned up too high)... Take this with a grain (or two!) of salt! :-)
