Regarding the lifting of other robots

[indiv0]

Hello, our team has been wondering about the legality of lifting other robots onto the pyramid.

Our first question is:
Is it legal to indefinitely lift a robot on your team, provided the other member team in the alliance knows of this beforehand and has agreed to it, and that the lifting robot is touching the pyramid?

Second:
Provided that any length/robot diameter restrictions are not exceeded, would a robot lifted up by another robot to a higher level on the pyramid be considered a climb?

Third:
Would they have to touch every step of the pyramid on the way up for it to be considered a climb, or would our robot touching the higher level be enough?

Fourth:
If the answer to the third is yes, would simply touching each level with an extended arm or something (while being raised) be considered valid?

Thanks in advance!
