Delivery Robots Take the Metro in Shenzhen

In Shenzhen, China, delivery robots have started to move through the metro, entering stations using elevators. To avoid hindering people, they operate only during off-peak times, assessing situations using AI, which is also used for route optimization. During the testing phase, the robots are tasked with replenishing the inventory of 7-Eleven stores in metro stations, but later they are intended to handle additional deliveries and become 'integrated into everyday life'.
