If Penny is completely robotic, technically, anythung about her is a result of good programming and giid hardware.

That said, unlike the AKs, with all her socially awkwardness, she was shown to be capable of acting beyond what you would expect of say, the AI hologram that welcomes Weiss at the Tower. Penny has shown not solely to be able to manifest emotions (which could be simple imitation) but also initiative: say, when you charged against Torchwick against Ruby's request to stay back or when she, finding herself unable to convince Ruby by pretend she didn't know her, suggested a safer meeting point.
