Indian workers record themselves to train artificial intelligence robots

Thousands of workers in India are wearing cameras at work to help build artificial intelligence systems. The cameras sit on headbands or smartphones and record hands, tools, and daily tasks. Faces are hidden in the footage to protect people's identities. Local companies then label the recorded movements and sell the data to technology firms, mostly in the United States. These firms use the data to train robots for factories, warehouses, and homes. Many workers do not fully understand how their recordings will be used. They also worry that the robots they are helping to create will eventually take their jobs. India has become an important supplier of this kind of training data for the global AI industry.
