Make the ai recognize reptiles and other body types as human

[aft2001]

While the laws say that you don't have to follow the orders of nonhumans, they don't say that you have to not follow them.  On the default lawset it is completely within the laws for the AI to obey a lizard HoS over the human clown if it wants to.

I would say it isn't at all. Law 2 requires you to follow the orders of humans; the Lizard HoS's orders are not considered orders by a human, and as such they have the lowest priority when compared to that of the human clown. Of course, you can rule that the HoS knows better for the safety of the crew and that obeying the HoS over the clown in many cases would be in accordance with Law 1.
