I agree, they do not mean literally that you must keep hands off of the robot, but you must keep "Hands Off" in the sense that you can't interface with the robot at all, through the bag, or whatever. Like CH95 wrote, treat the bagged robot as if it were inside a sealed crate, somewhere else.

In other words:
Hands Off means Hands (the appendages at the end of most human arms), but "Hands Off' means also paws, feet, hooves, fins, flippers, talons, eyes, ears, fingers, toes, legs, noses, wings ..... you get the idea.
