I think the string is being used more like a belt. You can see what's going on on the far side. The string is run through an eyelet, then tied off onto the pivot for that big cylinder. Said pivot is set up to run in a slot along the frame. So I think this is a belly climber that's using air and a PTO. That's my read on the arrangement of things anyways. I'm not entirely sure how they get onto the first rung and ratchet up, however.

Sir, you are correct. As for the first rung, we will let the pistons assume a straight up 90% angle first, the cylinders will extend, just enough to hook on to the first rung, and we will fire the cylinders, pull the robot half way up. We also have a kickstand mechanism in the middle of the robot, which will make our robot parallel with the 68 degrees angle. And at this point, the wrench will start pulling and that would get our front wheels past the first rung, engaging our passive hook.
