A delivery service in China has found a mesmerizing high-tech way to reduce on labor and maximize on efficiency.

The company has put scores of robots to work to sort over 200,000 parcels and packages a day.

Footage shows dozens of the yellow-topped robots shifting parcels from drop-off to pick-up points in the vast storerooms.

Employees scan a package barcode, feed the information to one of the robots, which then carries the parcel away to a different area in the sorting center.

The robots are self-charging and can work 24 hours a day, 7 days a week.
