I've been playing around with my Robonova, trying to get it to climb a rope. It is a lot more difficult than it appears, due to the balance when the robot is hanging by his hands. There is really not enough freedom of movement in his hands and arms, to do this successfully.
Anyway, he will pull on a rope though........ ;)

Ha! Very cool. A robot
Ha! Very cool. A robot powered elevator. Does he let the bear down gently, or just drop him to his death?

Not quite as simple as that, pips17
As soon as his feet leave the floor, the angle of the rope to his body changes. When one hand lets go it changes again. As far as I can tell, it’s not constant, either. I may try a different method - like absailing in reverse

A little speech added and you have a kids TV show with those two and their adventures
Really cool!
Enjoyed watching your “presentation”, great music.
Maybe a small pulley wheel on top to cut down on friction, to help the bear
be “pulled up”, and introducing a pawl and catch to the wheel would keep the bear
locked in position while the robot changes grip. Those thoughts popped into my head.
Very nice, enjoyed it.

Thanks for the tips, Springload.
To be honest, I was in too much of a hurry to get it going, as you can tell from the pile of books and kitchen broom
