Unlike its car vending machine concept, Alibaba's ideas for robots have been more mundane and mainly confined to warehouses (the same kind that Amazon uses). But today, the Chinese ecommerce titan introduced a package-delivering'bot that uses LiDAR to navigate around. The package locker it carries uses facial recognition to ensure it's got the right recipient before popping open its doors. The G Plus, as it's called, is being developed with Chinese company RoboSense. The robotics outfit lends its LiDar technology to the robot, which uses it for the same purpose as self-driving cars: To create a 3D map of its surroundings and avoid obstacles.
