Very interesting way to climb. When I was a kid I used to climb various trees but nothing straight and branchless like a coconut tree. Just looked up this on youtube[0]. The safety harness makes sense and the the loop for the feet does as well. As it goes, in India the coconut climber job is dwindling fast so this robot climber is very good replacement at the moment.
