The film, starring Rajnikanth and Aishwarya Rai, has an an estimated budget of 150 Crores (£20.6m).
“Robot is a huge movie, with an amazing star cast and music from A.R. Rahman, the best there is. It's a sci-fi film, with never-seen-before special effects. It's a true entertainer," said the film's director.
Rai, who earlier worked on Shankar's hit Jeans, commented: “This film is very special to me. It was an absolute pleasure working with Shankar again after so many years. I hope everyone who watches the film, enjoys it.”
Like Rai's last project Ravaan, the film is a trilingual project and will be releasing in Tamil and Telugu as well as Hindi.
Robot is expected to hit box offices worldwide September 24.
