The 24-year-old worker was reportedly adjusting a metal sheet being welded by the machine when he was stabbed by one of its arms.
“The robot is pre-programmed to weld metal sheets it lifts,” one of his colleagues told the newspaper.
“One such sheet got dislodged and Lal reached from behind the machine to adjust it. This was when welding sticks attached to the pre-programmed device pierced Lal's abdomen.”
Some local media reports claimed Mr Lal was electrocuted during the accident and died at the scene, although his cause of death has not been confirmed.
Police are viewing CCTV footage of the factory and interviewing dozens of workers who were there at the time as the investigation continues.
Assistant Commissioner Rajesh Kuwar told the Indo-Asian News Service: “The company management and the contractor have been booked on charges of causing death due to negligence.”
The Maruti Udyog Kamgar Union has demanded a full enquiry into Mr Lal’s death and increased safety measures governing work with robots.
SKH Metals could not be reached for a comment.
It came after an employee at a Volkswagen factory in Germany was killed in another accident involving a robot.
