Haven't we seen a few FRC robots that don't even have wheels? :)

Original discussion here. And Pinecone, it was only 6 years ago :)

Re: FRC Robots Aren't Real Robots?
 
Great question! For a number of years, I led the Engineering Team of the Northrop Grumman's Unmanned Ground Vehicle Subsidiary (Remotec). Our "Robots" have been used by military and first responder bomb squads. These are teleoperated vehicles and save lives every day they are in use. They are called bomb squad robots. Autonomy is one facet of a robot's capability. " Self drive cars" are "cars" first. So I would take issue with anyone who claims that FRC Robots do not qualify as Robots. The autonomous period of a match demonstrates they are capable of achieving this goal also.

1) Autonomous mode, is most certainly "robotic".

2) An activity based on an entire match of autonomous mode without the hands-on excitement and interpersonal communication of tele-op would attract - just guessing here - 3% of the kids currently involved in FIRST?

3) "“Never argue with stupid people, they will drag you down to their level and then beat you with experience.” - Mark Twain

;) Just for fun ...

To keep any future debate lively, ask the debaters to find me an "autonomous" machine that isn't operated by something that is alive (biological wetware). I'll be surprised if they are successful. (1)

Someone usually operates (turns on and/or configures) "autonomous" machines.

Once an autonomous machine is configured and activated, in a very real sense it is equivalent to a rock I drop from my hand. (2)

Note 1: I'm setting aside debating whether any biological wetware machines spontaneously/randomly evolved out of previously inanimate matter.

Note 2: Typical autonomous machines certainly aren't like rocks in *every* way, there are plenty of differences; but in a philosophical debate ...

According to a 6 year old I once met at a demo, our FRC machine was not a robot because, "How can it be a robot if it doesn't have a face?"

Trying to explain FIRST and FRC to my boss led to this sort of misunderstanding/disagreement. To him (and in our industry), these are robots:







A lot of principles apply but to this day I wonder if using the word "robotics" in my resume was a stretch considering the industry and that my boss may have felt i was overselling myself a bit (not that it matters, he likes my work for the most part). The definition of a word is what the speakers of the language deem it to be, and in automotive manufacturing, FRC ain't the definition of robotics (not to say they don't think we're cool).

FIRST robots definitely meet many commonly agreed upon definitions of robots. Some will disagree. Good for them. In my opinion, it's not worth arguing over.

Can confirm. Work in IT. Spend lots of time with manufacturing companies, hospitals, energy companies, and more. Engineers do not agree on anything.

Robots have sensors for input right? Well, what is a controller if not a set of sensors for input? It's a silly debate.

Forgive me if you've heard me say this before, but I think FIRST needs to make a game where there's a huge penalty for not moving at all during autonomous. The number of teams that do nothing in autonomous every year is ridiculous.

As an example rule, let's say that driver control doesn't begin until you leave the starting zone of the field. You can either make your robot drive a few feet or hope that your teammates come to push you out of the zone.

There's no team where turning on motors for a few seconds is out of reach. If they can't it's because they've prioritized something else.

I get the frustration that many of us feel when many robots don't move during autonomous. This rule at first glance sounds good, but there are some practical problems to think about. The first is that you would need to define the game in the right way to make this practical. In many games there is a substantial penalty when your robot interferes with another robot's autonomous mode. In others there are potentially really bad mistakes that can happen in autonomous that should be avoided. Some teams opt to do nothing not because they can't but because they don't want a mistake to cost their alliance. We have had sensors that prevented a collision during autonomous, making our robot not move very far.

Another consideration is that this rule will definitely lead to more matches (potentially many more) where robots sit and do nothing. There is nothing more frustrating in FRC competition, for any team but particularly for new teams, than having a dead robot.

Yet another consideration would be that sometimes the field communication system can mess up a team's autonomous mode. We had at least one match this year where another team not being able to connect to the field led to a reset of the communications. Our autonomous mode had been selected, but when the field reset this choice was lost. The robot did nothing, even though it was consistently scoring. We ended up losing that match 118-119. That was frustrating but nowhere near as frustrating as it would have been if as a result of a field reset we had not been able to move at all for the entire match.

I think if you want to increase the number of robots that do something in autonomous the best solution is to provide a sufficient incentive to get teams to do something. In general positive incentives tend to be more effective in game theoretic / behavioral economic motivation anyway. (Humans tend to underestimate the chance of events triggering negative consequences and overestimate the chance of events triggering positive consequences.)

I think the GDC tried to implement something like this in 2015, and the result was that even fewer teams bothered with autonomous at all.

This year struck a good balance in my opinion. 2 points just for running motors a few seconds, and 3 more bonus points if you could just make it over a defense. I wouldn't mind seeing some form of disincentive for smashing into the opposing alliance wall at full speed though.

My take:

If you don't leave zone X (in the right direction) by the end of auto, -2 points/robot AND temporary disadvantage. If you do leave, +5 points/robot. If you leave in the wrong direction, then that can be discussed later--game-dependent.

The temporary disadvantage would be that for 10 seconds, you are stuck in auto unless you leave the zone (by any means). At 10 seconds or zone exit, you're put into teleop.


That being said, points for running your motors is good, with more points for doing more being better. But I suspect that a mild point penalty for not moving in auto--and a piece of code, from FIRST, that is set up for "move so far"--would provide a large incentive to teams to make sure everybody moves in auto.

I like the way you're thinking. There's some room for creativity in the autonomous mode rules. It's rarely something other than gain a few points for completing easy objectives, more points for hard objectives, and a big penalty if you interfere with the other alliance.

As for the specifics, I like the idea of losing some points, and not just gaining them. In games with the scoring levels we've seen recently, 7 points probably isn't enough though. 2014 had 5 points for driving over a line and a lot of teams didn't do that. My first thought had been to make moving in auto worth like 50 points, but then that might make games where one partner was missing unwinnable from the get go. If instead there was a penalty for robots left in an area the alliance isn't totally hosed.

I also like the idea of a temporary disadvantage. This is something FIRST has done before. In the 2004 game if a certain action didn't happen in auto then gamepieces were held back for a certain number of seconds.

Also, as mathking brings up, there may be some teams that don't do anything for fear of messing things up. One way to reduce this is to eliminate penalties for interfering with the other teams during autonomous.

I think it's a good idea but at the same time I disagree. There have been matches where they start the match without us, even when we were banging on the glass, so we didn't get a chance to do auto since we didn't have time to select one, I'm notrying even sure if we had codecided loaded from the Rio, like I don't know if it was reading it. If they waited until everybody was ready like they are suppose to, it may work, but things can mess us and the auto on a robot may not start.
