The YOGO indoor delivery system integrates the cloud, stations, robots and IOTs (such as lifts and gates) to provide an efficient, well-organized indoor delivery network. It covers the seven stages of the last 100 meters of delivery: reception, storage, sort, delivery, collect, feedback and return. It improves dispatch efficiency and management of in-building visitor-flow and security and also enhances receiver experience while guaranteeing privacy. The back-stage system monitors operation status through a response plan with auto-solve functionalities, remote processing and on-site manual troubleshooting. YOGO uses self data analysis for each site, constantly optimizing the service plan for better efficiency experience.
