Asimov's Three Laws are more or less a standard now, in the real world. However, Remnant didn't have Isaac Asimov. Having a 'soul' also possibly exempts Penny from the Second Law.

I believe there is a set of Military Laws of Robotics, and with those swords and Ironwood's involvement, plus her role in 'saving the world', I think she's more likely to be bound by those laws.
