India has no dedicated rules for physical AI. Existing laws on product liability, consumer protection, workplace safety, data protection and sector-specific regulation may apply, but most were created for systems where human control is clearer.This creates uncertainty over issues such as “how to certify an autonomous factory machine or what clearances an autonomous delivery robot needs”, said Kazim Rizvi, founding director at policy think tank The Dialogue.What else? Liability remains unclear too. Current laws could classify an autonomous robot as a defective product or raise industrial safety concerns, but do not clearly say who should be held responsible among the manufacturer, AI developer, technology provider and company deploying the system.Also Read:Beyond code, 9,000 physical AI jobs open in India as global demand rises to 80,000
