Cases 1 and 2 are potentially not a CLIMB. If you’re contacting only the side rails, then yes, you’re only contacting 2 levels at a time and the climb will count. If you’re using the corner rails, you’re contacting more than 3 levels at a time, and the climb will not count. (Remember, the floor is a level.) Cases 3 and 4 are then moot.
Cases 5-9 are almost certainly a climb. However…
In all cases, remember that the robot must contact Level 1 before contacting Level 2.
Well, while the noted ones are indeed CLIMBs, what’d you define as “firing a grapple”? If you that you define it like a grappling gun, then your first problem would be in having a grappling gun on the robot.
Option 1 is illegal, in my opinion. I am assuming your robot is on the floor (level 0) when it deploys the grapple onto the vertical rail. The grapple then slides down until it hits the corner’s horizontal rail. I assume you start to pull the robot off the floor at this time. Before you leave the floor, your grapple is around the vertical rail in zone 2, resting on the horizontal rail in zone 1 and touching the floor in zone 0. Clearly, this is not a legal climb.
Carry this reasoning to Option 2 and it is also illegal.
Will have to go back and look at the other options before commenting on them.
