Oh yep, almost forgot about that, thanks for clarifying.

Re: Climbing Rules
 

If your robot is above the third bar, would it still be considered in zone 3?

Re: Climbing Rules
 

If you are partially above level 3, and the lowest point of the robot is above level 2,the highest level you achieved would be level 3.

Re: Pyramid Rule Question
 

The video is not official; the rules and Q&A are. If the rules don't say there is a time limit for climbing, then there isn't one.

climbing question
 

when the robot can start climbing on the pyramid?

Re: climbing question
 

As soon as the auto period is over you are allowed to start climbing.

Re: Climbing In 3 Sections
 

I think the welds at the corners are what make corner-scaling difficult.


I keep thinking of climbing a ladder. A normal person would put a foot on one rung, a hand on the next, before starting the climb-this would not be a legal climb (three levels are contacted).
Taking it a step further - let's say the ladderclimber is standing on the first rung and tries to ascend to the second. This person is not allowed to touch the third rung for stability - (s)he must fully release from the first rung before contacting the second.
This with the understanding that each level begins with the horizontal plane tangential to the top of the rung - I can't think of how to consistently and explicitly contact a round horizontal member at only one point, and that one point exactly at the vertical top. But, this game is only 27 hours old, clarity may come.
The 1/9 opening time for Q&A feels like a lifetime away. Especially since the response time is historically such a wild card.

Re: climbing question
 

I don't see a rule forbidding climbing in autonomous. Am I missing something?

Whether it's a good strategy is, of course, another problem.

Re: Climbing In 3 Sections
 

Not the first rung, just the ground.
The first and second rung are consecutive levels.

Re: Climbing In 3 Sections
 

Right, but if Level 0 is considered a level, then there's a problem.

Re: Climbing In 3 Sections
 

I think the bot can "ride" the corner pole, including the "bumps" at the junctions. The only plan I can think of to climb and not violate the 2 bar rule, is to cimb up the inside (which only has enough room for 1 bot), or climb up one of the corners.

Climbing up an outside side has the problem of: Eventually you can only hang on one bar as you grab the next higher one. When you are hanging, the center of mass will cause 1/2 your robot to hang inside the pyramid. Not a deal killer, but it takes additional motor power to swing the bot back to the outside of the pyramid to clear the lower bar.

For corner climbing, the bot grabs onto the horizontal pole on each side of the corner, and the thrid point of contact is the verticle pole. The verticle pole keeps the bot from swinging under the pyramid.

Re: climbing question
 

I have been searching for the section or rule that states you need to be on the pyramid at the end of the match to score the points. So far this is what I have found.

"3.1.5.2 CLIMB Points
Points are awarded for the highest Level achieved for every ALLIANCE ROBOT that CLIMBS its PYRAMID. The Level to which a ROBOT has CLIMBED is determined by the lowest point of the ROBOT (in relation to the FIELD). CLIMB
point values and Levels are defined in Figure 3-4.

A ROBOT has CLIMBED its PYRAMID if it contacts the PYRAMID in
A. sequential order (Level 0, 1, 2, 3) during ascent and
B. no more than two (2) Levels simultaneously.

If a CLIMB is considered unacceptable (e.g. a ROBOT has touched non-adjacent Levels or more than two (2) Levels at a time), a Referee will indicate a rejected CLIMB by turning the offending ROBOT’S PLAYER STATION LED strings yellow. The ROBOT will be ineligible for CLIMB points unless and until it begins a new CLIMB from the floor, Level 0.

3.2.1.4 G04
ROBOTS may only be removed from a PYRAMID under the following conditions:
A. by the TEAM,
B. unpowered,
C. and under the supervision of a FIRST Technical Advisor (FTA), FTA Assistant, Referee, or Field Supervisor."


This seem to imply that once a robot has climbed the pyramid correctly, the alliance will be awarded points determined by how high it has climbed. The is no mention of staying on the pyramid until the end of the match.

Rule G4 might apply since the robot would be removed from the pyramid in a manner inconsistent with G4, but since that rule is under the safety section of the rules, it is possible it only applies after the match is over. A violation of G4 results in a Yellow card but does not mention loss of points

Thoughts ?

Re: climbing question
 

I believe this would be legal since, as you said, there is nothing saying you must remain in position to recieve points. Coming back down should be legal because the rule about what qualifies as an acceptable climb states that if a climb is ruled unacceptable, the robot will have to come down and restart the climb. I expect this will most likely be part of a rules clarification though.

Re: climbing question
 

Even that I'm doubting, since the rules pretty clearly say you can go all the way back down if your climb is ruled invalid:
