Plot
Dr. Vaseegaran (Rajinikanth), a scientist specialized in robotics, creates a sophisticated android robot in his own likeness after a decade of intensive original research. He intends to present it to the Indian Army. His mother (Revathi Sankaran) suggests naming it Chitti Babu.
At the International Robotic Conference in India, Vaseegaran introduces Chitti (also played by Rajinikanth) to the delegates. In the meantime, it is revealed that Vaseegaran's mentor, Dr. Bohra (Danny Denzongpa) is preoccupied in a botched research project to create a similar superintelligent android robot. Meanwhile, Chitti endears himself to Vaseegaran's girlfriend, Sana (Aishwarya Rai) and helps her cheat in her medical school exams. When they are caught, Sana lies to the investigators that she does not know Chitti; thus Chitti learns that humans may choose to lie for self-preservation.

Vaseegaran decides to modify Chitti's neural schema to allow him to understand human behaviour and emotions. Later Chitti successfully applies his text book knowledge of symphysiotomy to handle the complicated childbirth of Latha (Devadarshini), Sana's friend. The procedure is covered live by the media. Dr. Bohra arrives to congratulate Dr. Vaseegaran on the achievement. He also lets Chitti pass the AIRD evaluation.
Soon, Chitti begins to see Sana as its romantic interest and makes advances. This triggers a confrontation between Vaseegaran and Chitti. Sana tries to explain to Chitti that she can love him only as a friend and asks him to forget her. Chitti later deliberately fails in an evaluation conducted by the Indian Army. Vaseegaran chops Chitti into pieces and throws it away in a landfill site.

Chitti finds Vaseegaran, but as Chitti is about to kill him, the police force strikes AIRD. The robots assemble themselves into sphere, snake, tower, and drill bit formations to defend themselves. One of the robots is immobilized by a grenade explosion, and is taken into custody by Vaseegaran. He uploads a computer worm into Chitti's network which temporarily brings down the robot army. Chitti identifies the source of the worm and sends a "self-destruct" command to the robot. The robots assemble in the shape of a giant robot and chase Vaseegaran's armoured bus. Vaseegaran uses the data he had backed up from the destroyed robot to de-magnetise the robot army, collapsing the giant formation. Chitti is pulled into the bus by a huge magnetic wall, allowing Vaseegaran access to Chitti's internal control panel, through which he instructs all the other robots to self-destruct. He then removes the red chip thus calming down Chitti.
In a court hearing, the jury rules capital punishment for Vaseegaran, citing the large number of casualties and damages to public property caused by the robot army. Chitti, explaining to the court that the law allows it to be treated as material evidence, if not as a witness, explains that it was Dr. Bohra who caused Chitti's deviant behaviour. He shows the court, using his eyes as 3D projectors, the video footage of Dr. Bohra installing the red chip inside him. The court decides to drop all charges against Vaseegaran, while concluding that Chitti should be dismantled in order to avoid further mishaps of the same kind in future. Back at the lab, an emotional Vaseegaran tells Chitti to dismantle itself. While taking off his parts one by one, Chitti apologizes to Sana and Vaseegaran for the problems he caused. However during the final minute, before completly dismantling himself, Vaseegaran comforts Chitti saying that he alone was not responsible for what all happened. And that the humans were also responsible, because whatever Chitti had learnt and gained, was from the humans. A smiling Chitti finally takes out his head and dismantles himself, with all others around him including Vaseegaran, Sana, Lata and her baby son crying.
Twenty years later, in 2030, students in a science museum are escorted by a guide towards a showcase that has Chitti's body parts arranged. The guide tells the students that Chitti was the most advanced humanoid robot ever created, but it was dismantled due to "certain reasons". A curious student (Shriya Sharma) asks why, to which Chitti's head responds, "I started to think".
