Nadine, a robot receptionist at the Nanyang Technological University (NTU), is staring at the visitor in front of her. "I remember you," she says. "You were here last Saturday."

Finally, she settles on: "We talked about your job." At the National University of Singapore campus, a driverless cart attempts to navigate along a crowded walkway.
