Police and other obstacles
Florence, did you need something?
You have a grip reflex. I press in your palm and your fingers close.
My kind is known for hanging on once we grab something.
Robots don't have that reflex. They touch, visually verify, then close their grip. On a jump, it's too slow. They fall.
However, if they hook their hands before they jump, they could grab the bar.
Practical and boring. I think we'll all be happier if you take your time and come up with a proper solution involving catapults, bungee cords, and duct tape.
