drama with human-like robots

I was wondering if anyone know any drama with robots that seems to have a human heart, and tend to sway the conceptions of what is human.

I came across this and watched it, and it was beautiful.

I have seen anime titles such as Plastic Memories, Chobits, Time of Eve, and I tend to really like these sort of stories.

Thanks in advance :)))
