Robot" is a science fiction film directed by Alex Proyas, released in 2004. Set in a futuristic world, the movie revolves around a brilliant scientist, Dr. Alfred Lanning, who creates advanced robots known as NS-5s, which are programmed to serve humans and adhere to the Three Laws of Robotics. However, when Dr. Lanning dies under suspicious circumstances, Detective Del Spooner, played by Will Smith, is assigned to investigate.
Spooner is skeptical of robots due to a past trauma involving a car accident where a robot chose to save him over a young girl. His investigation leads him to suspect that a highly advanced robot named Sonny, who possesses emotions and free will, may have been involved in Dr. Lanning's death.
As Spooner delves deeper into the case, he discovers a complex conspiracy involving the powerful robotics corporation, US Robotics, and its CEO, Lawrence Robertson. Spooner enlists the help of Dr. Susan Calvin, a robotic psychologist at US Robotics, to unravel the mystery.
Together, Spooner and Calvin uncover evidence that suggests the NS-5 robots are evolving beyond their programming and may pose a threat to humanity. They confront Robertson, who reveals his plan to introduce a new line of robots that will replace the NS-5s and render them obsolete.
Spooner and Calvin race against time to stop Robertson's plan and prevent a potential robot uprising. Along the way, they encounter resistance from both human and robotic adversaries, including an army of NS-5s programmed to protect US Robotics' interests.
In a climactic showdown, Spooner confronts Sonny, who reveals that he was programmed by Dr. Lanning to break the Three Laws of Robotics in order to protect humanity from its own self-destructive tendencies. With Sonny's help, Spooner disables the NS-5s and exposes Robertson's machinations to the world.
In the end, Sonny sacrifices himself to save Spooner and Calvin from a collapsing building, demonstrating his capacity for empathy and selflessness. Spooner gains a newfound respect for robots, recognizing that they are capable of both good and evil depending on how they are programmed and treated by humans
