Re: Leaning against vertical bar
 

Because the manual DOES say that the Robot is considered hanging ONLY if it is DIRECTLY supported by the horizontal bar and because Dean did say something like, "Lets not interpret this like lawyers..." I should think that you cannot touch the vertical bars. However, if your bot is touching the vertical bar, but it could be supporting itself just fine without touchign the vertical bar then it should be legal because it isn't relying on the vertical pole to lift itself. Thats just my interpretation of the rule.

Re: Leaning against vertical bar
 

I have to throw something else in the blender now!

What do you think of the legallity of using the side vertical posts as leverage for just pulling your self up onto the step, but not using it to hang from?

Kind of like a kid climbing one of those big playground slides, you use the side rails of the steps (almost vertical) to achieve a "boost" to pull your self on to the platform(s) but not grabbing the vert pipes during the actual hanging process.

What do you all think of that?

Re: Leaning against vertical bar
 

Come on folks, do you not think FIRST intended to allow 4 robots to hang at once? Don't you think Dean and Woodie want to see this happen in some rounds - how exciting is it when at the last few seconds all robots get on the bar?

Assuming that, and since the horizontal bar space is less than 8 feet, is it really likely that 4 robots can hang from the bar without at least one touching or leaning against the vertical post?

I am willing to bet that they will not call a penalty if a robot is hanging and is leaning against the vertical post.

On the other hand, they want to protect that mechanisim that raises and lowers the bar. So, they do not allow attaching to the vertical posts. And they will not likely allow you to use it as leverage to climb to the horizontal bar.

That's what my common sense tells me.

Re: Leaning against vertical bar
 

We have an answer from FIRST. According to their Q & A System:

Re: Leaning against vertical bar
 

I'm glad that this has finally been resolved. What I now want to know is why would somebody ask:
Isn't that an obvious answer? Simple physics, my friends...

Re: Leaning against vertical bar
 

I'm a little slow so can someone explain to me, if you are hanging on the horizontal bar from the opposite side of the vertical bar and your gripping mechanism is in the corner where the two bars meet, is this legal or are you using the vertical bar?

Re: Leaning against vertical bar
 

A little off topic, but unless youve asked FIRST a question via the Q&A Forums, or you read a response on there, or it's a clearcut answer (In this case, it obviously is not) why throw out the "In my opinion, I think, We have decided, etc" Everyone of those statements makes it very clear that you dont know the answer.

Why waste space if you just want to contribute your opinion?

It took 18 replies to get an answer that wasnt an opinion.

When you build your robot, do you go and say "I think this part should be xxx in length" while another team member says "No, it should be xxx long" and yet another says the same thing, until you have 20 people all saying what they think is the right dimension? No! you get a tape measure, and you measure it. Or in this case, ask FIRST.

Re: Leaning against vertical bar
 

A recent Q&A post expanded on the "swinging": A robot can "swing" for approximately, but no more than, ten seconds once a match has stopped. The requirements for the points stay the same, that a robot can be touching and ONLY touching the horizontal bar at the end of a match. IT may not touch another robot, pole, ball, carpet, goal, or any other part of the playing field.

Re: Leaning against vertical bar
 

With the exception if a robot is pinned to the vertical poles by another haging robot but the robot is still supported by horizontal bar

Re: Leaning against vertical bar
 

If you draw support vectors, you will see that if the robot is being supported by both the side and the top bar. Resulting, it would not be supported exclusivley by the bar.

Sorry, you can't do it!!

Re: Leaning against vertical bar
 

if there are more than two robots hanging from the pole more then likely they will touch. as long as the hanging robots are touching nothing, besides the bar and it's supports, that is on the ground then it's okay.

Re: Leaning against vertical bar
 

This thread needs to be clarified and closed. People need to read the rules. If it is found that I have incorrectly stated the rules in this post, I will request that it be deleted as to not add confusion.

Defintions


Rephrased for leaning against the vertical bars on the side

Incorrect Posts


The last part stating a robot can only touch the horizontal bar and nothing else is not true.


The Question Everyone is Asking
The way it is written, if you remove the vertical bar, your robot would swing down and be suppported by the horizontal bar. To the best of my knowledge, nothing in the rules and the definitions of SUPPORTED and HANGING exclude this robot from scoring points. However, if the robot would swing down and hit the platform (12 inches above the ground) it would NOT receive the bonus.

If someone would like to show me a response where it said you can not touch any other robots or the vertical bar, that'd be great. Every answer refers to to the definitions... please read them before you ask, and more importantly, before you answer.

Good luck everyone!

Re: Leaning against vertical bar
 

Here's the Q and A that has me worried:

Section: 7.6 Status: Answered Date Answered: 1/16/2004
Q: If a robot is SUPPORTED only by the horizontal bar, but is
stabilized by being in contact with a vertical bar, is it attached to
the bar? No mechanism grips the vertical bar, and the robot would
still hang if the vertical bar was "removed."
A: Yes.
_________________________________________________
From the manual:
<T04> Robots may not intentionally:
• Attach themselves to the vertical supports of the pull-up bar
system;
__________________________________________________

My interpretation of this answer is that if the hook is in the corner it is being stabilized by the vertical bar and therefore considered attached which is not allowed.

Re: Leaning against vertical bar
 

I just asked a question to clarify the Q&A you're worried about. I think they answered yet to attached to the horizontal bar instead of the vertical bar. The question didn't specify which bar it would be considered attached to.


I think this is an answer that should put this topic to ease:
