He introduces the robot, named Chitti, at a robotics conference in Chennai. Chitti helps Sana, Vaseegaran’s medical student girlfriend, cheat in her examination, then saves her from being assaulted by a group of thugs. Vaseegaran’s mentor, Professor Bohra, is secretly engaged in a project to create similar android robots for a terrorist organisation, but has so far been unsuccessful.
Vaseegaran prepares Chitti for an evaluation by the Artificial Intelligence Research and Development (AIRD) Institute, which is headed by Bohra. During the evaluation, Chitti attempts to stab Vaseegaran at Bohra’s command, which convinces the evaluation committee that the robot is a liability and cannot be used for military purposes. Vaseegaran’s effort to prove Bohra wrong fails when he deploys Chitti to rescue people from a burning building.
