Al robots' 'physical' education

The race is on to teach humanoids how to move like people in the real world — even folding towels

HAN SUYUAN China News Service PRIMARY students interact with a humanoid robot named Xiao An after a science lesson in Hefei, China.

Now that artificial intelligence has mastered almost everything we do online, it needs help learning how we physically move around in the real world.

A growing global army of trainers is helping it escape our computers and enter our living rooms, offices and factories by teaching it how we move.

In an industrial town in southern India, Naveen Kumar, 28, stands at his desk and starts his job for the day: folding hand towels hundreds of times, as precisely as possible.

He doesn’t work at a hotel; he works for a startup that creates physical data used to train AI.

He mounts a GoPro camera to his forehead and follows a regimented list of hand movements to capture exact point-of-view footage of how a human folds.

That day, he had to pick up each towel from a basket on the right side of his desk, using only his right hand, shake the towel straight using both hands, then fold it neatly three times. Then he had to put each folded towel in the left corner of the desk.

If it takes more than a minute or he misses any steps, he has to start over.

His firm, a data labeling company called Objectways, sent 200 towel-folding videos to its client in the United States. The company has more than 2,000 employees; about half of them label sensor data from autonomous cars and robotics, and the rest work on generative AI.

Most of them are engineers, and few are well-practiced in folding towels, so they take turns doing the physical labor.

"Sometimes we have to delete nearly 150 or 200 videos because of silly errors in how we're folding or placing items," said Kumar, an engineering graduate who has worked at Objectways for six years.
