That would appear to be correct, yes.
My understanding is that the yellow block makes contact with the corner of the pyramid, where there will be the surface of the bar at a 90 degree angle to the bar we latch on to, and there will be some metal between these two bars. Both of which are clearly depicted in Ken's diagram. The yellow block should act with a force on these objects, and assuming the robot has a tight enough grip to not fall off (which is obvious) then the robot should not rotate on the pyramid.

Re: Climbing the pyramid
minimal clamping force would be required for this idea because of the torque bar but it wouldnt be a bad idea to grab all the way around the pyramid's tubing to prevent falling
this method takes as much energy, torque, and power as described before
Yes, the yellow bar is meant to stop the "claw" elements from rotating

Adnaan, make it so only people with the link can see the video.

Getting video help
I followed Matt's instruction and that did not work????
With your climbing ideal do you still get the top points if the claw is around the lower bar therefore part of the robot is in the lower zone?

Re: Climbing the pyramid
we won't get points for that, the last stage of the climb has yet to be determined

Sorry for the unclarity on my part - it's Adnaan who needs to change those settings since he uploaded the video himself. Other people cannot change the privacy settings of the video.

Re: Climbing the pyramid
I also thought that if we were on the ground our claw had to stay in zone 1 only, if we grab the horizontal bay we would be on the floor and in zone 2?
I thought that was not allowed.

Re: Climbing the pyramid
being in the area above the first bar is allowed since its where the robot touches that counts, and grabbing the first bar is legal from what I can tell

Must the arms be completely fixed in place once we deploy them? If not can we just retract them back a little bit so we can make it to the top level?

The first horizontal bar is ground one. If we make contact with anything on the pyramid above the first horizontal bar, it will be considered making contact with level two. And this design doesn't have any of those problems from what I can tell...

Re: Climbing the pyramid
only scoring considers what zone your robot is in and not where it is contacting

Re: Climbing the pyramid
Going up the outside allows the robot to be larger I think.
If this is legal it might be a good alternative to keep working on.
The side bars of the rack tapper in which does effect the robot claw placement and the width of the bot.

Re: Climbing the pyramid
We had concerns today.
1st
Is there something in writting yet about parts that protrude outside the perimeter.
The claw the arm that holds the claw?
We read the manual and found where there can not be any protrutions
This rule would make it impossible to climb up the outside.
We need this rule determined.
2nd
Placement of the arms to allow us to flip and make it to the top zone.
Adnaan is auto cading this.
I will not sleep well until we solve this

Re: Climbing the pyramid
we are allowed have protrusions beyond the frame perimeter as ling as the robot fits in a 54" diameter circle, we can have as many appendages as we want protruding outwards in that circle, like in my screenshots.
G23:
A ROBOT’S horizontal dimensions may never exceed a 54 in. diameter vertical cylinder.
In other words, a ROBOT must always fit inside a cylinder with a diameter of 54 in. This method for restricting ROBOT size requires extra diligence if a ROBOT’S geometric center shifts as various appendages are extended and retracted.

Re: Climbing the pyramid
sorry mr smith i had answered that on another section of the forum
*answering mr smiths question as to the protruding arms
'In the STARTING CONFIGURATION, no part of the ROBOT may extend outside the vertical projection of the FRAME PERIMETER, with the exception of minor protrusions such as bolt heads, fastener ends, rivets, etc.'
we had fully skipped over the area that said "in the STARTING CONFIGURATION", other than that there is NO area in the manual containing the word 'protrude' or 'climb' that says that an arm CANNOT leave the vertical projection of the frame perimeter
and what ken is saying now :

Re: Climbing the pyramid
Basically there is a 54" circle that is always on the field, always flat on the ground. if you look at the field from the top, the robot cannot go outside of that circle, regardless of the orientation of the robot

Re: Climbing the pyramid
I now get why you had the circle drawn.

Are we worrying about numbers yet?
kind of a heads up when working with designs for climbing the pyramid, the distance between bars is roughly 34 7/8", so this is the minimum distance our armspan would need to be

Re: Climbing the pyramid
currently working on required length of torque bar/positioning of robot at pyramid base
I may be able to finish tonight, but wont have anything presentable until tomorrow

Re: Climbing the pyramid
turns out i was mistaken mr smith...
i hate to be the bearer of bad news, but right now ive got nothing but bad news on the climbing front

Re: Climbing the pyramid
because the robot starts off on the ground, horizontal, then lifts into more vertical-ish position after grabbing the first bar, only a few inches of the robot reaches into zone 2
this means the second bar has to reach ~30" up to grab the second bar
also, this is using an arm that is 26" long

Re: Climbing the pyramid
I do not see it this way.
I need to see what you are saying.
Will we get a visual soon

Re: Climbing the pyramid
Im quite confused on how only a few inches of the robot makes it into zone 2 with an arm on the end of the robot. anyways, you could have an arm that extends once we were vertical since the robot would probably have a smaller projected footprint. Think vertically
