Here I am proposing the use of an additional device to hook to far, but reliable asperities for redundancy purposes. Can be used to go down as well (ad indicated in ClimbingDown). Can be like
both with adjustable yaw to cover a sector area.
The traction cable or the telescopic tube will be used to go up or down the wall.
A camera will look for far and reliable asperities.
