706 deploying minibot
 

Here's a video of our 2011 minibot deploy and climb.
Not the fastest bot yet.
KISS on the deploy.

Please check the rules and the Q+A.

The minibot cannot be above the plane of the 18" line after it breaks the plane of the base of the tower. Hard to tell from your video about this.

Can you site a reference? I don't interpret it that way.

Re: 706 deploying minibot
 

Sure.

<G21>
HOSTBOTS may DEPLOY MINIBOTS only onto their ALLIANCE‟S TOWERS and entirely below the DEPLOYMENT LINE. Violation: RED CARD. TOWER is disabled if MINIBOT is DEPLOYED above the DEPLOYMENT LINE.

Re: 706 deploying minibot
 

G21 Alone does not make your deployment illegal, however since deployment starts at the instance the Minibot breaks the tower perimeter, your deployment would be illegal, if at any point in your arc the minibot is above 18"

Re: 706 deploying minibot
 

Boy, read and reread that and still don't interpret it that way. No one at todays miny regional had any issue with it.

Draw a side view of the HOSTBOT and TOWER. Draw a horizontal line between them at 18" above the TOWER BASE. Draw a vertical line at the edge of the TOWER BASE. See if your any part of your MINIBOT is above the horizontal line, when it's on the TOWER side of the vertical line. If so, you're gonna get a RED CARD if an observant ref is watching.

Re: 706 deploying minibot
 

I don't necessarily read <G21> as prohibiting a host bot nor a minibot from breaking an imaginary plane at the height of deployment line as long as the hostbot nor the minibot is in contact with the pole.

Clearly, a host bot in contact with the pole above the deployment line, or a minibot in contact with the pole above the deployment line before the minibot has separated from the hostbot, are violations of one or more of:
<G20> ROBOTS/HOSTBOTS may not contact their own TOWERS above the DEPLOYMENT LINE. Violation: PENALTY for contact.
<G21> HOSTBOTS may DEPLOY MINIBOTS only onto their ALLIANCE‟S TOWERS and entirely below the DEPLOYMENT LINE. Violation: RED CARD. TOWER is disabled if MINIBOT is DEPLOYED above the DEPLOYMENT LINE.
<G22> HOSTBOTS may not contact their ALLIANCE‟S MINIBOT while any part of it is above the DEPLOYMENT LINE. Violation: TOWER is disabled


Chris Fultz interpretation "The minibot cannot be above the plane of the 18" line after it breaks the plane of the base of the tower." is just one potential interpretation of the rules. I would suggest Bruceb pose question to the GDC. BUT...


Correction (thanks Vikesrock): the GDC already ruled...and the vertically swinging minibot deployment in which the minbot breaks the deployment line imaginary cylinder is a violation.

I think the deployment shown in the video meets the intended spirit of the rule and the field judges will have enough of a problem with monitoring for violation of <G21> when a pole contact is being made. I doubt most field judges would want to trust themselves to measure an imaginary cylinder at exactly 18". Will we see a special measuring tool?

Re: 706 deploying minibot
 

Perhaps the refs or inspectors can ask you to demonstrate that the MINIBOT is entirely below the horizontal plane after DEPLOYMENT...that should be possible before/after a match?

I'd like to see the alternative interpretation, how does it work?

Re: 706 deploying minibot
 

SO do the rules mean that at no part of the minibot deployment(when your hostbot moves the minibot into position to climb) can your minibot be above 18in.?

Re: 706 deploying minibot
 

Post #8 in this thread by Squirrel does a great job of describing the rule as interpreted by the GDC in the Q&A

Re: 706 deploying minibot
 

Well, G21 says
<G21> HOSTBOTS may DEPLOY MINIBOTS only onto their ALLIANCE‟S TOWERS and entirely below the DEPLOYMENT LINE. Violation: RED CARD. TOWER is disabled if MINIBOT is DEPLOYED above the DEPLOYMENT LINE.
G22 says
<G22> HOSTBOTS may not contact their ALLIANCE‟S MINIBOT while any part of it is above the DEPLOYMENT LINE.

Deployment line is defined as
DEPLOYMENT LINE – located on the POST, approximately 18 inches above the top surface of the BASE.

LOCATED ON THE POST there is no reference to a plane here or anywhere. It is a line on the post so my interpretation is that your hostbot cannot touch the minibot while it is on the tower post above the DEPLOYMENT LINE.

THe deployment line does not exist anywhere but on the tower post.

Re: 706 deploying minibot
 

Bruce, that unfortunately disagrees with what the GDC has ruled in the 2 Q&A posts I linked to. I would recommend posting your reasoning to the Q&A for additional clarification if you are hoping to stick with your current design.
