Is that how it works?
Is it Determination being channeled through physical attacks that causes the harm, or just the physical attack itself? I know that having a physical body and having determination are linked together, but how can you say it's one or the other?
I think you're making a lot of assumptions here. If monsters can only be hurt by determination, then how does someone like Gaster die? How do monsters 'fall down' if they can't be injured? Why are the monsters in the ruins scared of Toriel if she can't hurt them?
I'd ask why Toriel could hurt Flowey, but Flowey is kinda in the middle between monster and human, so he may be an exception to the rule.
You're basically saying that monsters are invincible to everything except humans here, which is blatantly untrue.
I personally think a robot would be less effective than a person, because it lacks the SOUL and emotions to really hate monsters, but would otherwise be a threat.
At least until a ghost possesses it.
