Food is loaded into a robot at the Bowling Green State University campus in Bowling Green, Ohio on Thursday, October 13, 2021. Robot food delivery is no longer the stuff of science fiction. Hundreds of little robots – knee-high and able to hold around four large pizzas – are now navigating college campuses and even some city sidewalks in the U.S., the U.K. and elsewhere. While robots were being tested in limited numbers before the coronavirus hit, the companies building them say pandemic-related labor shortages and a growing preference for contactless delivery have accelerated their deployment.
