First, two new picket fences were put in place. There was no metal wire in the RAM, we used zip ties to fix the picket fences to the cage. Then we removed the handbrake of the robotic rover to loosen the rope. We put the handbrake back and untied the rope. We then put back the tarp and secured it with zip ties.

Note that the zip ties we had are not very big, so we had to put a lot of them to be extra secure.
