The Wansha Station on Shenzhen Metro Line 2 has achieved a groundbreaking milestone: the world's first instance of robots independently navigating the subway system to deliver goods. These innovative robots can autonomously board the subway, plan the most efficient routes, and deliver items to Wansha Station and other 7-Eleven stores situated along the line. This revolutionary delivery method is a collaborative effort between Shenzhen Metro and Vanke, specifically designed to address the challenges of delivering goods to subway-adjacent stores.
