Does anyone have a video of this robot climbing? I’ve been trying to figure out how it got up there from the picture but am so far unable to. :confused:

I can describe it, if that helps. That arm that you see is articulating about the elbow and a shoulder within the robot. It latches on and pulls the robot up via a cord. Secondary hooks engage to hold the robot in place, and it repeats the process.
