No, as John said, the VAR is used to deliver a hook to the chin up bar. It then detaches (hangs from the cable connected to the hook)... then the robot winches itself up from the side of the platform. The only load on the vertical bar during this process would be from that tiny device.

Yeah, I will see if I can build it anyway with Patrick. Just too cool to pass up
