I took my daughter to see her perform about two years ago... I thought she was very poised and lovely. She is not yet mature enough to emote the meaning behind some of her material, but that should not diminish her talent. We didnt find her robotic at all... just very young and gifted:)
To clarify my comment, the concert I watched on TV had some informal background chitchat where she talked about family and such. She seemed almost Mormon in her perfect presentation and thoughts on family and life. Very managed. I am somewhat of a fan, and definitely appreciate her talent.
