Post URL to your autonomous mode
 

I just love the autonomous modes and love watching other robots do it. So I thought I would commit our team to putting together a video of all the various teams doing their auto mode.

I already started this but realized how much work it was searching for all the videos and knew I would miss some good ones.

So to be part of this 2007 autonomous video please do the following:

• All videos must be from official 2007 competitions, no practice videos.
• All videos must be downloadable like from Soap videos. Give the URL.
• Want both auto mode delivering the ringer and defending successfully from a bot delivering ringer (a hard task).
• One video per team of one time auto mode, we will use only 15 seconds max at a time. So choose your best onetime video.
• Exceptions:
• Video of two or more teams a ringer on a side.
• Exceptional or funny auto mode actions (like the dance one team did) or taking out a ref (wait that is not funny).
• Give your team number, how auto mode is done (i.e. cmucam sonar or luck)
• Give team stats on success rate etc.

I CAN NOT USE YOUTUBE VIDEOS. SO DON'T SEND ME THOSE URLS.

Not sure if we will use all the stats, but we will look at them and get our creative crew on it (well I haven't told them yet about this but once I push submit they will hear about it).

Looking forward to seeing these videos and seeing the whole thing together.

Can I just post the IP address of our robot and you can download it direct to see it?

Re: Post URL to your autonomous mode
 

I am not going to link to video because my auton consisted of this one line of code:

ARM_RecallPreset(7);

It unfolded the arm, saving us ~8 seconds of the teleop period. I hope to have something a tad sweeter for IRI, though.

Re: Post URL to your autonomous mode
 

I down loaded your two favorites. Both had sound only in windows media and didn't paly in quicktime. I pulled it into my media editor and it only had sound portion no video. Maybe it is a driver issue with me or problem with files.

Also be sure to say the method used to do auto mode (IE camera).

Re: Post URL to your autonomous mode
 

Both look good.

Re: Post URL to your autonomous mode
 

Good video, but I can not download youtube, at least I don't know how. Also be sure to tell me the method (IE camera).

Re: Post URL to your autonomous mode
 

These particular videos, since they are Wildstang-provided and not by SOAP, are encoded with the xViD codec, which is technically superior to Windows Media. You can find a copy of it here: http://www.xvid.org/Downloads.15.0.html

Re: Post URL to your autonomous mode
 

Here is a autonomous compilation video that I recently made, showcasing our successful caps. In order, from the video's sequence, the matches are:

NJ Match 39 (This keeper actually didn't count, as it was supported by the stinger.
NJ Match 11
UTC Match 64 (One bot from each alliance capping, us on blue, 1124 on red.)
Galileo Match 22 (Nice close up shot.)
Galileo Match 82
Galileo Match 90* (1126 positions correctly, but knocks off their keeper as they back away. We cap ours on the same alliance.)
UTC Match 52**
NJ Finals 1*
NJ Finals 2***

Match 52 from Galileo, Match 52, and the NJ Finals are my favorites. (I'm still amazed at how we scored in match 52 after slamming into the rack and pulling up from beneath the spider.) As for our method, we used a single ultrasonic sensor to determine the proper distance from the base of the rack. During the matches at NJ, we used the CMUcam to align left/right towards the light, if it were in the view of the camera, and if not it would proceed to use the sonic sensor code. At UTC, we experienced camera troubles, and decided to just use the sonic sensors, and try our best to determine/guess where the spider leg would be after the rack had been moved. At championships, we solely used this method, and scored during 3 out of our 7 qualification matches.

The asterisks indicate my preference on which are the most entertaining to be used for the video, three stars being the highest.

Re: Post URL to your autonomous mode
 

Here is a direct link to Team 1629's Autonomous video (wmv) file.

http://www.gearsinc.org/images/auto_1629.wmv

These are from the elimination matches at Chesapeake.

Navigation is performed by camera and gyro.
The camera is hard-mounted to the robot (no pan/tilt).
It uses the Gyro to get withing viewing range, and then locks in with the camera. Both heading and range are provided by the camera.
The vertical car and rotational arm (two axes of motion) are positioned based on feedback from potentiometers.

Once we got the camera so it could see the lights, we mised one, and scored two.

In addition to a direct near-side score, we are working on scoring on the opposite side of the rack (for off season games).

Re: Post URL to your autonomous mode
 

Great compilation video. Tell me when the others are ready.

Re: Post URL to your autonomous mode
 

I used to have that on my computer. But either way both media editors can not use this format. sorry.

Re: Post URL to your autonomous mode
 

Here is a link to a compilation on youtube.

http://www.youtube.com/watch?v=36Em65OpwCY

If you need it, I can put the file up on a filesharing site.

All navigation was done based on camera feedback, with a gyro used to stabilize the robot while scoring the keeper itself.

Palmetto Q49 (run through the rack) - http://www.youtube.com/watch?v=b8uEfDExUR4

Our "Center Best" autonomous mode (the best of 14 modes including "Martian Rock") works like this:

1) Look for lights from the starting position

2) If we see two lights (very wide rectangle), make a choice:
2a) Centroid near the center, choose the dark foot
2b) Otherwise choose left or right depending on which the centroid is closer to

3) If the centroid is near enough the center, skip the next step

4) Attempt to acquire "the beam" (straight out from the foot) by turning the robot to move and track the centroid on the OPPOSITE side of the viewfinder as what it currently is. Continue driving this arc until the rectangle is either wider than it is tall or the tilt of the camera indicates that we're too close.

5) After arriving "on the beam" or if we start out with the light in the middle, drive the robot tracking the centroid in the center of the viewfinder using a PID controlling the speed targeting a pre-determined camera tilt value which puts the front of the robot about 2-4 inches INSIDE the rack.

6) When (if) the Easy button trigger hits the spider foot, activate scoring by dropping our face, cutting the vacuum (dropping the tube), raising the face and simultaneously backing the robot away from the rack. This is the same scoring sequence used automatically in tele-operated mode which is what made our robot so quick to score and hard to defend. We had no communication delay between the drive and manipulator when scoring.

7) If we arrive at too close a tilt or it takes too long to hit the trigger or the number of lights change, engage a retry sequence that backs the robot up a bit, waits for a new light acquisition, and goes back to step 5. This is why TyRap VII would back up sometimes during its approach to the rack, sometimes even right at the start which was rather disconcerting to the drive team.

To see some of our less-than-successful attempts at side and reverse (other end) scoring, pull the Palmetto and UCF autonomous from BitTorrent.

And here is our own autonomous video compilation offering...
http://www.DarkMatterFLL.org/2007HOTAutonomous.wmv


Method: Camera

We used the camera both to steer towards a lamp and to position at the spider for scoring. The camera was mounted on the arm via a linkage so that, theoretically, it would remain somewhat level as the arm moved through its operating range. However, before using the camera, we raised the arm to the low-level spider scoring position to prepare for stable tracking while the robot drove. After the arm stabilized in driving position, control was transferred to the camera driving function while the robot was still at its starting position. In retrospect, we could have saved time by having the robot drive onto the field while raising the arm as it appears many other teams did.

Our first autonomous program would score only on a low-level spider. We were so pleased with the result that we spent March 9th at the Great Lakes Regional developing a mid-level spider scoring program. You can see the effect of the development process reflected in the poor scores shown below on March 9th. Mid-level presented a problem because, when we raised our arm to the mid-level position the keeper held by the arm blocked the camera from seeing the lamp. We solved that problem by waiting until the robot had almost reached the spider before raising the arm all of the way to score.

Arriving at Curie we had another problem to solve - our camera seemed to be distracted by the bright lighting. We hadn't had camera problems like that before - we should have loaded the FIRST-supplied camera values first thing on reaching Atlanta. Loading those solved the problem, but we should have done it earlier in the day. Live and learn.

This has been a great autonomous season for us - we learned a lot. We enjoyed seeing what everyone did with autonomous mode this season and working our own autonomous. It was fun to be able to successfully develop a new autonomous mode while at the Great Lake Regional, and it was especially thrilling to be able to partner with Team 1114 in autonomous mode together. We're looking forward to next time.

Re: Post URL to your autonomous mode
 

One video of our autonomous mode on Galileo is here:

http://www.thebluealliance.net/tbatv...p?matchid=4326

We were pretty lucky to get it working since our camera wiring harness still had some shorts in it until Thursday afternoon in Atlanta. We never had a chance to try to power up our 2007 camera before ship and were not able to establish comms at VCU. We had done as much work as we could with our 2006 camera during fix-it-windows. There are a number of posts on the problems we had operating the camera in polled mode using three virtual windows.

This link is for our simplest mode that seeks the target with the highest confidence value (assuming we see two targets). If you watch closely, the robot rotates to the target drives fast until it is 12 feet from the target, drives slower and stops at 8 feet. At that point the arm is raised to the scoring height (all three levels can be selected via the LCD control panel) and the rest of the mode uses the gyro and timers to finish up because we thought the camera would be blocked at the mid or high level.

Curie Q56 http://www.thebluealliance.net/tbatv...7/cur_qm56.wmv

This match is my favorite because 716 shakes the rack with its dead reckoning auto attempt but MOEzilla hits it anyway on a slightly offset spider. Also, with 4 teams attempting keepers there is a lot of movement.

We use the camera, gyro, wheel encoders and occasionally sonar and IR sensors. If I get some time I will writeup something about the decision making and step based nature of the code. Also I will try to lookup our stats later but I wanted to get a video to you in time.

That is classis! I love it. Problem is it says the video is not available for download. Bummer I would like to use it. Do you know of a downlaodable version and what team was it?

Re: Post URL to your autonomous mode
 

here are a few videos of team 79's autonomous mode. they are all from atlanta on the Galileo field.

http://www.soap.circuitrunners.com/2...al/gal_078.wmv
http://www.soap.circuitrunners.com/2...al/gal_101.wmv

we started by clamping the ringer and waiting until we found the light. we chose beforehand whether we would then wait 5 seconds extra for another team's autonomous to move out of the way. then we turned toward the light as we drove forward. once the camera told us we were close enough we quickly spun the wheels backwards for a short time to make us stop immediately. we moved the arm to a preset position based on a potentiometer, then let go of the keeper and backed up.

Re: Post URL to your autonomous mode
 

I always enjoy watching 79's auto mode. the flip over is really something to watch.

You are defintely in the video. I just finished this morning in collecting the videos. I have 31 robots at this point doing auto mode.

Fanatastic. I didn't have a video for you guys, I added the video to our list.

Team 1629 goes to the far side of the rack at PARCX
 

The clip below shows the auto mode that we never got to try at regionals.

In this match, 5 of the 6 robots had an autonomous mode. In this clip "Sticky" the Garrett Coalition (1629) bot makes a highspeed run to the far end of the field, sideswiping a blocking robot and then turns back to the rack and rings a keeper on the middle level.

A gyro is used to hold the heading in the straight run and initial turn, then the camera is used to get a range and bearing on the target.

Re: Team 1629 goes to the far side of the rack at PARCX
 

that was great, soemthing we had planned but ran out of time, glad to see you do it.

Re: Post URL to your autonomous mode
 

If its not too late to post videos... Here is ours which unfortunately were all (technically) failures. However, it consistently saved us critical time by flipping down the gripper and backing up a little bit. Plus, it was always suspenseful and somewhat entertaining to see how close/way far off the bot would be each match.

As for technical details, our method is almost identical to team 25's:

At UCF, we had planned to use the camera to run some decent (but mostly un-tested) autonomous modes, but when it caught fire during practice day we never had the time to figure out what exactly was wrong.

The entire robot was re-coded/ported to EasyC between UCF and the Championship event, and a single Vex ultrasonic module was mounted just above the rear bumper, and a magnetic read switch from home security systems was mounted on the arm base and arm chain to determine when the arm was in the correct place. The code is fairly simple, and basically had two cases: 1) Too far: Drive forward 2) Too close, back up. Variables were used to determine the ideal distance, and the window decreased each program loop until it was as close as reasonably possible.

With no way to point the robot, it was sheer dumb luck, and we simply were not as lucky as team 25. On the positive side of things, we determined that the camera's *wiring* burnt up, not the actual camera. So hopefully we will have something more advanced set in motion come Mission Mayhem time :).

Re: Post URL to your autonomous mode
 

I am working on putting the videos together. So it is not too late. Good tries. I have decided not to include any FIRST non-competition videos. But I have not thought to include unsuccesfull tries. Let me think about it.

I think you gave a great effort. I know we could not have put together our autonomous in the midst of competition, so I commend you.

This video has been a lot of hard work and being with a team (1902) that their season seems to never stop (met last night) there is not a lot of time. I am getting close but not quite there.

Re: Team 1629 goes to the far side of the rack at PARCX
 

In talking to others, I have decided to include only videos from official competions else the project would never end and it puts everyone on same playing field.

But let me say, you did something we wanted to do.

Re: Post URL to your autonomous mode
 

Here is what I have so far on the video. I put all of them together have about 30+ robots.

Now the problem I have had is that the video is 9.5 minutes and 130mb. Youtube has a limit of 10 minutes and 100mb. I can't seem to figure out how to shrink the video more so that has held me up.

I am on the road a lot this summer, I am in Korea now and back to Orlando for six day and then in Colorado and California for the next month.

If anyone has ideas how to either shrink the video it would help or post it somewhere besides youtube. I am using Vegas Movie Studio 6.0.

Thanks

Re: Post URL to your autonomous mode
 

I don't know what the restrictions are for FirstTube, but this would seem to be appropriate: htp://tfirsttube.org

http://www.putfile.com/ has a limit of 200 megs, so you should be ok. You can also upload to google video if you download their desktop uploader.

There are also likely options in your video editor that allow you to decrease the video size or quality to make the file size smaller.

Re: Post URL to your autonomous mode
 

Thanks to Joe of 330 I am using putfile for the video.

See the video at:
http://media.putfile.com/FIRST-Autonomous-modes-2007

Please do the following:
1. Make sure I have the right bot number with the right video piece.
2. There is one section I do not have numbers, tell me what the bots are and I will change that.
3. I will add robots I missed but I need to be able to download the video and it must be in mpg mode, I had trouble with some of the AVI videos. It must be a video from an official 2007 competition, no off season or practice sessions.
4. No I don't want to change your robot video for another video segment. I spent a lot of time looking at a lot of videos. It takes a lot of time and I have very little of that. so hopefully you will be happy with what I put in video, tried to use the one you suggested in emails.
5. If you want the video let me know especially if there is someplace I can upload it so everyone can have it.
6. If someone wants to edit this video better let me know, video editing is not my strength.

Once we get the final video I will post it to a new thread in CD.

Re: Post URL to your autonomous mode
 

I believe the two teams in the segment you don't have numbers for are 191 and 1038.

Re: Post URL to your autonomous mode
 

Sorry to bump up an old thread, but I think this is the best place to ask this question. All of you who had butt-kicking autonomous modes last years, what did you use? Which sensors, custom circuits, and special logic? What pointers would you have that generally lead to a quality autonomous mode?

Thanks

Re: Post URL to your autonomous mode
 

#1 best secret. Hardware done by end of week five, that gave us a week to practice driving and auto mode. Auto mode just takes time. So dependable hardware and done with enough time to spend lots of time perfecting it.

#2 we had a 3/4 size field to practice auto mode.

#3 we used easyproC for fast developing and more people could do it.

#4 we proto typed lots of sensors using vex to when we go the hardware we didn't start from scratch but knew what we could do and not do with sensors and had routines working.

For 2007 we used the camera. 2006 we used gyro mainly. Previous years we use IR sensors and wheel encoders. Really depends on the contest. We have also tested sonic sensors.

Suggest practice using vex with all the sensors to get a feel for them.

Re: Post URL to your autonomous mode
 

Very interesting. Thanks Doug. Obviously we'd love to (and hopefully will) have the hardware done by the end of week five. We're planning to do our own thing with a coprocessor this year, so we're starting it early to give us time to work out kinks. We'll definitely try to get some time on a practice field and test as many sensors as we think we might use, so we can use them if we need to.

Re: Post URL to your autonomous mode
 

In 2006 the hardware guys saw how important the auto mode was. So they decided that it was not an option to finish by week 5. They kept the pressure on it and cut out things to make it done by week 5.

I have been in seasons that it wasn’t even finished at the 1st competition and took all of the practice day, then we had times we finished just before time to put it in the crate, then last year finishing at end of week 5. I tell you the team was so much more ready for competition by finishing by week 5.

Re: Post URL to your autonomous mode
 

Thanks Doug. As a programmer, I hope they keep making autonomous more interesting and important, as that's the most interesting part of the competition for us (that, and designing good control algorithms for our drivers). I guess I'll have to try and ask our build guys to do their best to finish (heh, as if they don't already do), so we'll get as much robot time as we can.

Re: Post URL to your autonomous mode
 

Can you take the 2007 robot and do some of the programming? Assuming you have the same base. Try to do as much as possible before the week 6. Our programmers worked the whole time, but especially week 6.

Re: Post URL to your autonomous mode
 

We can. Better yet, we're working on a practice drive train right now, that will hopefully closely resemble the competition one. It will have an entire IFI control system with all the electronics, and we will be using it to program before the real one is done, and probably do some work on our co-processor solution before the season starts.

Re: Post URL to your autonomous mode
 

What are you using the co-processor for?

Re: Post URL to your autonomous mode
 

We're looking into using it as a learning experience and something big we (myself and a few others) can do in my (and some of theirs') senior year to learn and leave for the team to use. We have to first get the system up and running, probably building on what the AdamBots did and using a gumstix. Eventually, our goal is for the coprocessor to read and handle sensor inputs, as well as receieve the user inputs from the OI (via the RC), and do all computation and logic. We might end up leaving some sensors connected to the RC if it ends up being easier. We think it will be a great learning experience, but for game use, it will let us run as many sensors as we want, do high-level logic with them, and as much floating point and trig as we need to without worrying about the RC. If you have any comments, ideas, or suggestions, we'll be more than happy to hear them, as the project is still in its very early stages right now.

In 2003, first time they had autonomous mode, the then processor was very slow and bad. To do the autonomous mode we had to make a co-processor to process the quad encoders we used for the auto mode.

But the 2007 processor seems fine but I have always wanted to make a data logger.

After we get all the basics up and running, I had a few more advanced ideas in mind. One of them would be a StangPS resembling system, that would record the position (in x and y) and the angle of the robot, using a gyro and an encoder. Are you thinking of data logging for the in-game purposes, or something to be analyzed between matches? What data would you record and why?

[quote=sumadin;653237][quote=Doug Leppard;653228]Collect data during the game and if something goes wrong have data to check to figure out what went wrong. This is especially helpful in the auto mode period.

What would collect is the sensor data, but maybe readings on key parts of the robot.

I used to do very difficult autonomous games that the robot would do all the game in auto mode. Data collection was very important in figuring out what the robot was trying to do and what the sensors were reading.
