Depending on the type of robot and application, the torque limits may be way higher than what it takes to crush a human being. It’s not for shits and giggles that most robots are put in cages/behind barriers.

I work with a lot of small robots (they fit on a desk) and they will absolute smash the living shit out of you if they’re not set to low enough. Even on lowest torque they can break bones. Obviously they’re caged when used in production environments, but all safety can (and often will) be circumvented by staff because it’s inconvenient for them.
