In mountain forests, we often find some cliffs that are suitable for climbing. However, because of its cliffy steep, we cannot get to the mountaintop in advance to install safety rope for climbers, which causes that we have to give up some excellent cliffs to climb.
We can control the UAV with safety rope to fly to the top of cliff, find a big living tree, and lock the lock catch of carried safety rope on the tree-walk of the big tree to achieve the installation of safety rope.
