One afternoon last month, as I was crossing a busy four-lane street that runs through the University of Pittsburgh campus, I looked up to see a robot blocking my path.
This wasn’t unexpected. Over the summer, several four-wheeled, knee-high robots had been roaming campus, unmarked and usually with a human handler several feet behind. Recently they’d multiplied, and now they were flying solo. They belonged to Starship Technologies, I learned, an autonomous delivery service rolling out on college campuses across America.
As a chemical engineering Ph.D. student at the University of Pittsburgh who uses a power wheelchair, I figured it wouldn’t be long before I met one of these bots in a frustrating face-off on a narrow sidewalk. What I didn’t realize was how dangerous, and dehumanizing, that scenario might be.
