At the Chuangpin International Smart Logistics Park in Lanshan County, Yongzhou City, Hunan Province, the intelligent sorting system conducts orderly sorting of express packages.

Liu Jianhua (People's Photo): From handwritten waybills to electronic waybills, and then to delivery boxes with identification labels; From hand shouldering to automatic sorting, to unmanned delivery vehicles and robots... "Sweat Express" is transitioning to "Smart Express". The China Business Industry Research Institute predicts that the scale of China's smart logistics market will reach 79.3 billion yuan in 2023. The robot delivered the package to the workstation. "Your package has arrived, please enter your phone and pick it up in four digits." "Successfully picked up the package, completed another order today, so happy!" In an office building in Nanshan District, Shenzhen, Ms. Ge, a white-collar worker, successfully signed for a delivery. What sets it apart is that this express delivery was completed by a talking building delivery robot named "Xiaofeng". The "weight" of "Xiaofeng" is about 30 kilograms, with a length of 0.49 meters, a width of 0.42 meters, and a height of 0.98 meters. The "head" has a screen, and the "body" is divided into two express delivery compartments. When Ms. Ge enters the pickup code, it will automatically open the corresponding express cabin. Regarding this, Ms. Ge commented, "The operation is very convenient. I can send and receive express delivery from my own workstation, which has a strong sense of technology and future!" Two months ago, SF Express launched four building delivery robots in this office building, collaborating with the courier guy and backend system to provide intelligent express delivery services. The cabin volume of the robot reaches 70L, which can climb slopes and avoid obstacles. Currently, it can deliver 70 parcels per day. Xiong Chao, Senior Manager of SF Smart Building Solutions, told reporters that delivery robots are terminals in the ecosystem of smart logistics systems. Its investment can achieve zero contact delivery in CBD buildings, where people can receive express delivery at office checkpoints; At the same time, intelligent robots can also help delivery guys improve efficiency, reduce human errors and delays. This will greatly improve the delivery experience for the last 100 meters. This building delivery robot has complete perceptual and cognitive components as well as positioning and navigation components. Both software and hardware modules support self-diagnosis and redundant safety, enabling the robot to autonomously close closed-loop scenes. For example, due to the installation of intelligent IoT applications for elevators in buildings, when it is necessary to take elevators, pass through electronic doors, or pass through gates, the robot can send instructions through wireless signals to quickly open the door as soon as it reaches the target area. After the robot passes, the door can be quickly closed again. Could you please give me the middle seat? Xiaofeng is going to the fifth floor now? "" Let me perform a magic trick - press the elevator every other time "... When taking the elevator," Xiaofeng "will also interact with the people around him in a humorous way, which is very pleasing. Because it has connected SF Express's intelligent customer service system, when someone asks if certain items can be delivered and how long they will arrive, "Xiaofeng" can also answer questions. In recent years, similar terminal intelligent robots have become increasingly common in high-end office buildings, commercial complexes, campuses, hospitals, and other scenarios. Experts point out that these intelligent delivery services at the end of the line can help with delivery costs
