I saw elsewhere that he is a delivery robot.It’s an autonomous delivery robot system that rides the subway to restock convenience stores inside metro stations, using AI scheduling, LiDAR navigation, and self-driving mobility. The robot plans optimal routes, takes elevators, boards trains during off-peak hours, and delivers goods to multiple stations without human involvement.
It seems to be in Shenzhen, China, the same city as the drone police I mentioned last time.
