The world's first robotic self-portraits, painted by an android called Ai-Da, have been unveiled at a new art exhibit in London, despite the "artist" not having a "self" to portray. The surprisingly accurate images question the role of artificial intelligence (AI) in human society and challenge the idea that art is exclusively a human trait, according to her creators. Ai-Da is a life-size android artist powered by AI -- computer algorithms that mimic the intelligence of humans -- that can paint, sculpt, gesture, blink and talk. Ai-Da is designed to look and act like a human woman with a female voice. Her head and torso looks like a mannequin's and she wears a variety of different dresses and wigs, although a pair of exposed mechanical arms do give her away as robotic.
