The wig used for Chitti's 2.0 look had a silver streak in the middle, made out of yak hair,[3] while its leather jacket was designed by Vogt.

Dr Vaseegaran, who is specialized in robotics, created Chitti after a decade of unsuccessful attempts and intensive research.

Vaseegaran made Chitti interact with people outside the lab to socialize him with the outside world and saw how he used his intellects and abilities amongst humans.

Sometime later, Chitti successfully helped Sana's pregnant friend, Latha, give birth to a baby, despite it being complicated.

But then the robot fell in love with the scientist's girlfriend, Sana (played by Aishwarya Rai) and thus it caused conflict between them.

The court accepted the footage as evidence and acquitted Vaseegaran, but ordered Chitti to be dismantled due to how much damage and destruction he had caused.

[7][8] But Chitti is defeated and destroyed in his original form by the antagonist, which leads his CPU head to be rebooted in another advanced mechanical body, identifying himself as Chitti reloaded version '2.0', and will also fall in love with his female counterpart, the super-android Nila (played by Amy Jackson), also created by Vaseegaran.

As long as his CPU head is still functioning, Chitti is able to repair or fix back his minor parts such as his eyes.

Chitti's eyes are able to not only see and scan his surroundings to extremely acute detail, including X-ray vision, but they can also serve as high-definition projectors.

Chitti's only known weaknesses are flashing lights from photography or direct sunlight, which causes a "vision bleach" and temporarily distort his sight, and his susceptibility to battery drainage.
