Re: FRC...autonomous or driver-controlled competition?
 
emusteve is right. FIRST is a student based competition, and it should be about the students designing, building, and tweaking the robot. I know that are programmers are having trouble just getting the robot to work properly, not even considering autonomous. Most high schools and high schoolers just do not have the time or resources to create a fully autonomous robot. I am all for an autonomous period, and I am in awe when I see a program perfectly executed and perform the task it was given. FIRST should be about a balance between autonomous control and operator control. I don't think that FIRST should go to a fully autonomous control. I'm sure there are many other competitions that are available for an autonomous robot.

I agree with you Steve. I took on the task of mentoring our programming team this year. Lots of code was written, re-written and scraped. In the end, we have a function that improves joystick control and switch feedback to keep from overextending our arm. Autonomous mode is simple extending our arm ( a three step move) and driving forward.

What is coolest about this is that all of the code was written by the students. :) They learned how to use the IFI manuals to select a joystick input or designate a digital input. :) :)

I for one, have had enough of activities were the parents do and the kids watch. :mad:

Student Designed, Student Built, Engineer Approved!

Ok, I'm off my soap box. Back to the Discussion at hand...

Steve

I couldn't agree more. We would rather have the students do the work and fail to get a robot together than have the mentors do all the work and win. We have a policy that no adult touches the robot during competitions except for things like helping to pick it up and move it around. All programming, modifications, and repairs must be done by the students. Of course, mentors are right at their side giving instruction. It works if the kids were involved during the design and build. Last year we made it to the finals in St. Louis and the Semi-finals at the Nationals as a youth-built Rookie Team.

I believe that what Stephen said hits the nail on the head. I don't believe that FIRST could make the autonomous mode much more complicated without extending the time of the build season, and that is just something that wont happen. Unless a team has the resources to build a second robot, I know of teams who are hardly getting any drive practice, let alone time to write a complex code and still have time to debug and test. The length of the build season cannot be lengthened due to many reasons, mainly the mentors just cant take that much time off of work/families to sacrifice for the team. Another very valid point that someone mentioned is that because this is only a high school competition, the students do not get extensive programming experience. Now, if FIRST was a college competition, I can see it becoming much more involved, however since it is not, I don't see a big change in the near future coming.

The point is not whether a big change is coming or not, but whether one SHOULD come.

In any case,
I see a lot of posts here seeming to imply that students are not capable of designing (with mentor help), and programming a functional autonomous bot. I flatly disagree. Our robot doesn't do much during autonomous this year.. but that isn't because we couldn't get it to work. It was because we couldn't get it to work in the time we had: autonomous wasn't given enough of an emphasis.
If FIRST designs a competition that does rely on autonomy a lot more, teams will HAVE to get autonomous working, and will work on it. Autonomous is a bigger challenge.. not only for programming but for electrical and mechanical teams as well (All those extra sensors, well-built mechanisms needed for the robot to be able to function without humans watching over).

In general, going to a more autonomous-controlled competition will allow the students to learn more. It should not degrade to mentors doing the work and students watching, it should improve to students learning to get a tougher job done in the guidance of mentors.
And in the interest of not ranting forever, I congratulate FIRST on introducing the camera to autonomous this year. I think it is a step in the right direction. All they need to do is emphasize it more. Make it worth all the time that needs to be spent working on it.

Re: FRC...autonomous or driver-controlled competition?
 
I would have liked to see more options for autonomous methods this year.

I know in the past FIRST has had lines on the field that properly equiped robots could follow; this would provide an alternative to encoder wheels. The camera provides another alternative.

It just seems that your options this year are pretty limited to capping the tetra you start with, knocking a hanging tetra, or capping the vision tetra. All that any of those do is score points you could have gotten in the regular round anyway (although the vision bonus tetras are nice).

It just seems to me that this autonomous mode seems pretty watered down compared to last year. I'd like to see completing an autonomous objective give your alliance a unique advantage that can't be gained in normal play. Something like capping a vision tetra means a second tetra is added to the auto-loading zones for the start of the game.

Autonomous mode should be about options, which unfortunantly adds complexity.

You forgot grabbing tetras from the autoload stations and stacking them.

If you're very good (and very lucky), I think you can get 33 points in autonomous mode (plus another potential 10 at the end of the match for three-in-a-row across your home goals). I doubt anyone will come close to that, but 14 points (plus 10) doesn't seem out of line, and 20 (plus 10) isn't far-fetched. That's probably going to start you out with a good advantage.

That said, I see autonomous actions this year as being mostly prestige. I agree that they don't open up any options for playing the game differently.

Re: FRC...autonomous or driver-controlled competition?
 
Okay I have a question for everyone and I figured I should probably use this thread first instead of starting a new one.... Anyways my question is can you run your autonomous program again during a match? If we have a way to play our autonomous program again using our controls, can we set up our robot again and play it back? I don't recall seeing any rules against this but probably (knowing my recent luck) I have probably missed it. Anyways thanxs for the help!!!


GO 1403!!!

to just give a short reply to the thread starter:

personally, i don't think any of our "robots" really qualify for the name "robot." its kind of a misnomer, considering i've never seen one of our so-called "robots" protecting the life of another robot, following the orders of a human, or protecting the life of a human.

I agree with Greg. First autonomous should include more options to reach a common goal. These can be hidden to reduce complication, except for the personnel who have to regulate things such as IR sources. IR sources, lines, and color spots combined could allow for easier programming for rookie teams who can pick what they can program well, while keeping the interest of older teams who can use multiple sensors. Autonomous should be about variety and options. Thats how the real world works, right?

In my opinion, it's just too much information if you try and design a autonomous robot. You are now trying to throw another subject on top of learning a computer language. Learning how to program and learning how to program a robot are two completely differnt areas.

Well to be honest the real world doesn't cater to us like FIRST which would mean that there would be no infared or any disernable color blobs. Also, sensors are gaurenteed to have problems/fail. This situation actually happened last year with the infared reflecting all over the place. This question relates to the above quote. Is six weeks enough time to design and use the right sensors? I feel we would start approaching the informational limit for most high school students which I was taught to avoid as an engineer.

Why is it that First Lego League robots are fully autonomous, and yet the students "graduate" to teleoperated robots?

(I think that point was brought up at kickoff).

Re: FRC...autonomous or driver-controlled competition?
 
Good question... As a programmer I much prefer autonomous operation. In a few months I plan to write a white paper on an awesome project we are working on that would make it very simple and cheap to replace your RC with a PC running linux.

Probably because there aren't many robotics kits for a middle school kid. That is probably the only reason why they picked that kit. Easy to assemble and take apart.
