High Stakes Autonomous Starting Positions

Greetings to everyone. According to GameManual 1.0 rule , in order for a match to start, the robots must have no moving mechanisms, meet the preload conditions, be in the starting position, etc. there are conditions. So what is this starting position? According to the text, the starting line must be touched or its plane must be broken. As long as I meet this condition, can’t I start as follows?

You seem to understand the rule perfectly and your situation looks perfectly legal as long as the robots are actually breaking the plane and all other conditions are met.

I am not sure why you did not include the Figure SG1-1 which highlights the starting line in green. Rule says specifically, Contacting/“breaking the plane” of the Alliance’s starting line.

As a matter of form, it is better to quote the rule verbatim in your post rather than paraphrase like this:

<SG1> Starting a Match. Prior to the start of each Match, the Robot must be placed such that it is:

  1. Contacting / “breaking the plane” of their Alliance’s Starting Line. See Figure SG1-1.
  2. Not contacting any Scoring Objects other than a maximum of one (1) preload. See rule <SG5>.
  3. Not contacting any other Robots.
  4. Completely stationary (i.e., no motors or other mechanisms in motion).

I mention this because “moving mechanisms”, which are present in a vast majorities of robots, is different than the rule “Completely stationary (i.e., no motors or other mechanisms in motion).

That said, I think there is an ambiguity in the way GDC phrased Contacting / “breaking the plane” – does the ‘/’ mean “and”, “or”, or “and/or”? In this case, it would be nice if they wrote out in words what they mean.

Since by definition if you are contacting the line you are also breaking the plane of the line, adding “contacting and breaking the plane” is overly redundant. So it must mean “or” or “xor.” If it means “xor” and there is no way to touch the line without breaking the plane, than the statement would be redundant since “breaking the plane” would satisfy. Therefore, we know the rule means touching the line or (inclusive) breaking the plane.

G3, use common sense.

I know all of what you said, after all, we can touch the green line from the right side, is there anything prohibiting this, that is my question. :blush:

I will be very grateful if you stay on topic and be careful what I ask. :blush:

This is a bit ambiguous - “from the right side”? I am assuming you mean is it ok to contact / “breaking the plane” of the starting line from either side of the line? I see no clause in the rule indicating you must be contacting a tile on either side or not. Which usually indicates it is permissible.

GDC can be precise with its wording. In this case using ‘/’ muddles the clause needlessly.

Q&A will answer it for sure.

That’s exactly where I got confused, yes. We will probably struggle in the first tournament because that’s how we plan to start.

Can my robot be turned the opposite direction when the match starts?

Hard to say, since we do cannot know what “opposite” means in this case.

Just meet the criteria of SG1 in the current manual and you are good to go. The rule does not make any reference to robot orientation - you could follow the rule with your bot on its side if you wanted to.

Welcome to the forum.

It means facing the wall stake, would that be in violation of any rules?

Here’s your answer (20 characters)

So I’ve read all all themessages. I still don’t understand. It can be in any position as long as it is not behind the white/green line?

If you were to vertically cut a long the white/green starting line, it would have to intersect a part of your robot. Other than that you can orient it however you wish

Basically just make sure your robot is touching the starting line

so would this work?


(the robot is the pink rectangle, and the front is where the line is attached)

That does meet the requirement of SG1a. Assuming you also follow b, c, and d then you would be in compliance with all of SG1.

Again, whatever you think of as the front of the robot is not a factor in compliance with SG1.

No we don’t start touching just part of the robot musts be over the line
