Do you have a working autnomous mode?
 

Do you have a working autonomous mode? Please answer the poll and let us know how accurate it is, what the probability is that it will actually place a tetra, and any other important details.

(I know that some of this has already been addressed in other threads, but I want to readdress the issue now, after shipping)

Re: Do you have a working autnomous mode?
 

This year our team has come up with 4 auton modes.

-1. Starts with given tetra in center position-spins turret and caps center goal

-2. Robot starts in corner on auto loader side- robot drives to auto loader, picks up tetra, comes back and gets in position to cap corner goal.

-3. Robot starts on human player side-Hits hanging tetra and moves in position for human player loading.

-4. Robot starts on autoloader side - robot hits hanging tetra and moves in position in front of auto loader.

We do not have number 2 working exactly the way we want it yet due to the fact the robot must be positioned perfectly for it to work, but the others are working fine to the best of my knowledge.

Re: Do you have a working autnomous mode?
 

We got autonomous working Friday morning. After that, the Friarbot successfully knocked off the hanging tetra on the side closest to the auto-loader (scoring 1 point) in every match except for one, and that was because our alliance partners had us starting in the center where our autonomous wasn't designed to work from.

Re: Do you have a working autnomous mode?
 

Team 1370 has a working autnomous code that works all the time to knock down the hang tetra from ether side with the same code.

Re: Do you have a working autnomous mode?
 

Our auto (because we didn't have weight for the camera, but that may be changing :)) caps any goal on our side, if we start with the tetra, or knocks down either magnetic tetra. Then tries to get to the autoloader... sometimes we just go to the auto loader. Toward the end of Phoenix it was working 4 out of 5 times. Of course on the practice field it worked flawlessly every time :D

Re: Do you have a working autnomous mode?
 

We developed an Auto mode At the end of the day Friday at VCU (I think) that starts with a tetra and caps it on center. We tested it on the practice field. It missed once, because of the way we set it up, and the second time, it put it up but ended up "not fully capped" on the goal. Since the testing we adjusted the speed backing up after it drops down the tetra (which is why it didnt mesh well).
Unfortunately, our partners never wanted us to use it since most of them wanted to start with the tetra and were sure they could be more accurate with it.
Oh well. If we attend an offseason, we plan to execute our secret autonomous weapon. I put 50% in the poll, because after seeing it perform, I'm pretty sure itd work at least 50% of the time.

Re: Do you have a working autnomous mode?
 

We had a working autonomous mode when we shipped. We broke it at the Boilermaker Regional when an attempt to fix a joystick scaling problem inadvertently threw the PID tuning for our arm out of whack. A subsequent attempt to fix the PID ended up with it being too underpowered to reach the target position, or even to move at all when it was commanded to move a short distance. I didn't figure that out until Sunday after the regional was over.

Re: Do you have a working autnomous mode?
 

We do have a working atuonomous mode infact we have a whole leap of them. problem is deciding which oe that we need to use.

Re: Do you have a working autnomous mode?
 

We have a working autonomous. The bad thing is if the robot moves (which it did on the first day of our regional) it means that the autonomous code is not working. :ahh: If it places a tetra then something is seriously wrong!

Re: Do you have a working autnomous mode?
 

Team 1286 had two autonomous programs working at the Detroit Regional competition last weekend. Both programs swung the alliance tetra in the
direction of the corner goal to knock down the hanging tetra.
Success rate was 4 / 5 in competition, but 0 out of 2 in quarterfinals.

For two competition rounds, I programmed the auto mode to swing twice,
but the swing was too much and I lost the tetra during the swing!.

To prepare for Nationals, we will introduce mode to be ready to cap center
goal if tetra provided in middle (assumes both alliance partners will use
their arms to knock down tetras).

Re: Do you have a working autnomous mode?
 

Team 66 has a fairly good autonomous mode, focused on placing a vision tetra on any of the three center goals. At GLR, it succeeded in doing it 3 times during practice day and once during quarterfinals. Otherwise, it stops after pick-up or gets extremely close (I mean that when I say it, EXTREMELY C-L-O-S-E.) So accuracy is 90% when putting the tetra over the goal. But actually capping, less than 50%. We hope to improve that over at West Michigan.

Re: Do you have a working autnomous mode?
 

Our autonomous was a hanging tetra whacker. It had a 100% success rate. Then we decided to try something else. Since we have to swing our arm over the robot to get the hanging tetra, why not start out with the alliances tetra leaning on the back? We scored that one under the middle goal around 50% of the time after we programmed it. Our alliance scored a triple play in autonomous (only one that I know of) in Phoenix, when our partner (don't recall who it was) hit the other tetra on the other side under the goal. That made for a 13 point autonomous mode.

Re: Do you have a working autnomous mode?
 

Team 384 has an auto mode that takes the robot to the manual loading station so that when the 15 seconds is over our human player can take off and put the tetra on the robot. It worked every match.

Re: Do you have a working autnomous mode?
 

How does Team 1370 do either hanging one with only 1 code

Re: Do you have a working autnomous mode?
 

We do this also.
It's very simple... We don't even turn the 'bot. We just place it on the field facing the correct direction :P

Re: Do you have a working autnomous mode?
 

We have several, some we used at the Boilermaker, some we will use at Midwest and some we may wait until Nationals to unleash. (Al snickers in the background as he presses the submit button.)

Re: Do you have a working autnomous mode?
 

We hardly had any time to code except for at the regionals, but we managed to write two auton programs with another switch for which side of the field. One turrets and knocks the hanging one (we found turreting was best because if you just set the robot facing the right direction, then it wastes valuable seconds when the drivers have to straighten it back out), adn the other will drop the tetra we are holding into the center goal and then turret and knock down the hanging.

Re: Do you have a working autnomous mode?
 

what we do is knock down the hanging tetra and then go to the auto loader and pick up a tetra. hahahahahaha worked 9 out of 10 times.

Re: Do you have a working autnomous mode?
 

Cyber Blue's autonomous knocks down the hanging tetra from the goal. It is accurate, I would say, upwards of 100 percent of the time.

Re: Do you have a working autnomous mode?
 

Team 1251, The Techtigers have 3 programs and they all work 100% of the time. For some reason we always use the same one since it seems to be the one that fits our strategie the best.

Re: Do you have a working autnomous mode?
 

Other: Our autonomous is now working perfectly, but isn't supposed to cap. ;)

(Of course, we don't have anything until Kettering Kickoff)

Re: Do you have a working autnomous mode?
 

We knock down a tetra and then drive out and turn toward either the human loading zone or auto loading zone. Depending on which side we start on.

Re: Do you have a working autnomous mode?
 

we actually only have one code. interestingly enough, we programmed it only for the vision tetra. so much for creativity, but it makes up for the fact that we dont cap every time.

Re: Do you have a working autnomous mode?
 

We had one code to start holding the tetra in any starting position and cap it on the goal. If it was either side goal, the hanging one would be knocked down too. It was done all with the arm, no driving required. It worked every time except once.

Re: Do you have a working autnomous mode?
 

Team 11 starts with the given tetra, turns and places it on any of the home goals. If it is placed on a side one the hanging tetra falls. We got this to work in competition about 5 out of 6 times.

Re: Do you have a working autnomous mode?
 

Our robot can knock the hanging tetra down from either side 100% of the time with the same code.

GO 1403!!!

Re: Do you have a working autnomous mode?
 

We had one program to knock down the left side hanging tetra. It didn't work at first on the practice day, but they got it eventually, and it worked every time after that.
I had thought they were kidding when they said they were going to drive it so the arm was inside the goal and then make the robot "throw a tantrum," but that's pretty much what we did. It twisted 2 or 3 times inside, then backed out. Our arm folds up easily, so we couldn't bring it down on top of the tetra, it didn't have enough resistance to knock it down.

Once, we placed the robot too far to one side, and it didn't hit the tetra on the first pass(groans from everyone). On the second time through, it hit it and caught it. I didn't notice until we started moving and we had a tetra on our arm. :)

Re: Do you have a working autnomous mode?
 

Our coach wound up putting together some code to knock off the hanging tetra. Thanks to dead reckoning, he plugged in some random numbers.

And those numbers worked the first time, and every other time--so long as we aimed it right.

Re: Do you have a working autnomous mode?
 

1089 likes to start with a tetra, knock down the hanging tetra closest to us, and then head for the center goal. when autonomous ends we can cap the center goal in no time. it's been successful most of the time, and i'm pretty sure it will continue to be.

Re: Do you have a working autnomous mode?
 

we have 2 autonomous modes, one places a tetra on the center goal and uses this specially designed whacker, (old broom stick handle), to knock down the hanging tetra on the side. this works from either side.

the other one... well you'll just have to wait untill Atlanta to see it go!

look for either team 1114, 1503, or 1680, we all have the same bot, and code.

Re: Do you have a working autnomous mode?
 

Our new one's great. Like Chris S had said you'll have to wait to see it.

Re: Do you have a working autnomous mode?
 

well i put Places a tetra 100% of the time. does it count if you hit the hanging tetra? because we broke 1 and had us lower are pneumatic air pressure.
