Zart is a simple robot, that was one of the first to be created. His basic frame comes from being a prototype for the later created Smartbots. That’s not to say that Zart wasn’t created for a purpose, he was. What purpose? This is yet to be seen, only with time will we see what Zart can do.
Not much else can be said about Zart, except for he has been locked away for a long time. Now that Zart is up and going, who knows where he will go. But he has already shown that he is willing to explore. The big question is how much knowledge and capability does Zart posses?
