Fembot Central

There a robot girl who appeared probably once or twice in the first season.
She reappeared briefly in the latest episode (10) and gets shutdown/broken but another guy at around 17:00.
There's also some good damaged male bot in that episode for those interested.

Here's an album of screen shots of the relevant scenes. http://imgur.com/a/5Rxsm

It was never stated since she's a robot. She was made to find another male robot and merge to form a stronger one.
There is another muuuch younger looking robot though, also in that episode and others.

But if you wanna delete this just to be wary, I don't mind.
