China’s e-commerce giant Jingdong launched more than 20 delivery robots in Beijing on Sunday, The Paper reported.

Each robot is equipped with a maximum 30 boxes of packages at the same time, which maximizes distribution efficiency. The maximum travel speed of 15 km/h also greatly expands the delivery scope.

During delivery, Jingdong robots can autonomously stop at the distribution points. And, with the 360-degree environmental monitoring directed by radar and sensors, these robots can automatically avoid road barriers, passing vehicles and pedestrians.

They can also accurately identify traffic light signals and make corresponding decisions.

Earlier in June, Jingdong decided to put delivery robots into mass production. It has also launched robot projects in dozens of cities, including Shanghai, Tianjin, Guangzhou, Guiyang, Wuhan and Xian.
