The short figure creeping around the Carnegie Mellon University campus store in a hooded sweatshirt recently isn’t some shoplifter, but a robot taking inventory. Andyvision, as it’s called, scans the shelves to generate a real-time interactive map of the store, which customers can browse via an in-store screen. At the same time, the robot performs a detailed inventory check, identifying each item on the shelves, and alerting employees if stock is low or if an item has been misplaced.
