A Chinese delivery service has found a mesmerising high-tech way to reduce on labour and maximise on efficiency, putting scores of robots to work to sort over 200,000 parcels and packages a day.<br />Footage from the warehouses of Chinese delivery service Shentong Express Tracking (STO) in Yiwu, Saturday, captured dozens of the yellow-topped robots shifting parcels from drop off to pick up points in the vast storerooms.<br />STO employees scan a package's barcode, feed the information to one of the robots, which then carries the parcel away to a different area in the sorting centre, directed by the data taken from the code. The robots are reportedly self-charging and therefore can work 24 hours a day, seven days a week.<br /><br />Video: Ruptly/AP/Newsflare<br />Music: Big Bang Fuzz
