Autonomous end game
 
So we've had the autnomous longer poll but what about autonomouse at the end of the game, I know I have seen it discussed but don't recall ever a poll. I would personally like to see it.. what do you think?

That could be extremely interesting. Have the first 15 seconds and the last 15 seconds of a match be autonomous. It throws in more unknown variables and would be much harder to program, I would imagine. I would love to see that.

I would love to see it but what about all those teams that don't or can't do autonomous mode. Wouldn't it be somewhat anti-Climatic for the end of the game? to see X amount of seconds a bunch of robots doing very little?

For those teams that simply don't do it, it might encourage their programmers to take on the challenge of being able to successfully perform autonomously.

Our team actually discussed this when we were speculating the color hint at the 2006 Championship.

I'm not sure. It depends on how that would be worked out. Would your robot, using this year's game as an example, be in the middle of scoring, then all of a sudden, it would stop and autonomous would take over? Would there still be autonomous at the beginning? Also, would the human operators have to step back? There would be some serious penalties if they didn't. It would throw the whole game. Interesting...I can't decide.:confused:

i vote YES.

I saw our programming team take a 5 minute break once, so i know that need more to do. ;)

Personally I like the idea. I also think it would be cool if the beginning game auto mode was worth less then the end game. i. e. the 2004 or 2007 auto mode at the beginning with the Decisiveness of the 2006 auto mode at the end.

Last year I remember there being far more teams having successful autonomous modes. The amount of teams attempting to do autonomous mode is a function of how valuable it is.

I think it'd be neat to just have a simple one: have a white line demarking the 'end zone' that robots need to get into at the end of the game, maybe with a vision target near it as well. The white line could be used with the little infrared sensors we've had in the past.

The rule would be written like this:
For every robot that is contained in an end zone at the end of the game that was not in the end zone at the beginning of the final autonomous phase, that team's alliance scores 10 points.

So camping in the end zone wouldn't score you points, you'd HAVE to get there autonomously. It'd also open up defensive autonomous modes: teams might camp in front to block the opposing alliance from being able to earn bonus points.

I think the ideal implementation would have a 5-10 second pause between the end of teleoperated and the final autonomous mode. If you don't feel your robot is in a 'safe' position during this 5-10 second phase, you can hit the e-stop.

Re: Autonomous end game
 
Too many variables to consider at the end of the game, based on where you are what direction you are pointed etc, etc, it could be done, but I'm just saying that if it was so decisive you would see the drivers for so many teams trying to set their robot up so that their robot worked autonomously the best for the last 20 seconds of manned periods, and there would be those without autonomous programming who would just park themselves in the percieved way of the opponent's autonomous mode.

Not that it couldn't be done, but I think it would detract a lot and not be as interesting, and make autonomous 10 times harder, and looking at the autonomous from this year, it looks like we could really use that.

I do not think autonomous at the end of the game is very practical. I would be a big fan if the GDC was some how able to make it possible without having to jump over canyons.

The thing that is so great about autonomous is that it is very consistent, and you do not have to deal with too many elements when you are positioning your robot in the very beginning of the match and when you are choosing where to score. If you made autonomous at the end, you would have to some how waste seconds of your teleoperated period to set yourself up, or have to work harder and incorporate more sensors to where all of your sensors work together and get the task accomplished.

Add an extra autonomous period at the end - Sure.
Move the autonomous period to the end - NO.

I'm for it, but I don't see it very likely. But than again, the game will be different next year, so all the variables are completely different.

Why end the match 15 seconds early?

Re: Autonomous end game
 
It could be interesting if any robots behind a certain line at the end of teleop went into autonomous mode, but robots outside of that area did not, and then any robot in autonomous mode would have some multiplier on points scored during that period (i.e. game pieces scored by manual robots are worth 1 point each in the last 15 seconds, game pieces scored by autonomous robots are worth 5). Could lead to interesting strategies.

I don't think this is the case. If you had an infrared emitter or vision target in the bonus zone, then all teams would have to do in autonomous is spin around until they find the target, then drive towards it. Already in autonomous teams have to acquire the vision target, so that isn't terribly difficult. As a programmer, I can tell you that when the camera is working and you've got KW's code, it is actually very easy to program with.

To encourage teams from spending time in matches setting up and rather spend time in build period programming robust autonomous modes, an even better idea would be to have 3 lights above your alliance station, spread across the field. At the end of teleoperated period, a single randomly-selected light will light up, and THAT is the zone where you receive bonus points.

This is a very interesting topic. I would like to see more autonomous but there are a few problems that could come up when at the end of the game.
1) Doesn't the RC need to be reset to re-engage autonomous mode?
2) How would the RC differentiate between the beginning autonomous and ending autonomous?
3) You wouldn't see any last second efforts to race back to your side of the field and jump on a ramp like in the last two years

I like this idea but how would a robot differentiate between the red alliance side and blue alliance side. Do you remember the teaser during the final matches on Einstein last year? The red alliance home zone could have a red light and a blue alliance home zone could have a blue light and have the robot already knows which alliance it is on so it knows where to go.

You are forgetting about the fact that there will be 5 other robots and any number of game pieces and field elements to negotiate around. Navigating autonomously when you don't have prior knowledge of the terrain is extremely complicated. SImply finding a target and driving to it wont work. Over the last two years it has become apparent how much trouble teams have even when they know approximately where the target will be.

While I don't know for sure I would tend to assume that the competition port has an extra pin that could be used, other wise it could be taken care of in the default code.


Over all I think this is a very cool idea however it is also an incredibly impractical one. We see enough robots sit still at the begining of the match, why have it happen again at the end?
