Asa's and the human pain systems are vectoral. For Asa one would like to have one contact sensor wherever (Lego) bricks or (Vex IQ) beams are connected. Temperature sensors can be mounted alongside contact sensors or they can be more sparsely distributed. I.e., "burns" might be a less localized sort of pain as compared with "cuts." Internal pains are literally signaled from internal sensors of either sort.
