A 78-year-old retired university professor in Philadelphia has turned sidewalk defense into a personal mission by repeatedly stepping in front of automated food delivery robots. Carolyn Marvin, a communications scholar and the first woman to earn tenure at the University of Pennsylvania's Annenberg School, regularly stops the wheeled machines delivering for UberEats whenever she encounters them downtown. Marvin argues that sidewalks are shared public spaces that must remain accessible for pedestrians rather than commercial corridors for private tech companies.
Her sidewalk standoffs have attracted both online fame and lively local debate. Marvin contends that the machines, in addition to replacing human delivery workers, create physical hazards for elderly pedestrians and people with mobility impairments. While some passersby cheer her stance, others argue that she is unfairly preventing ordinary customers from receiving meals they already ordered and paid for. Avride, the Texas-based robotics firm operating the fleet across dozens of campuses and urban centers, programs cute facial graphics and sleeping animations to make pedestrians comfortable, though company representatives confirmed they are well aware of Marvin's actions.
The dispute recently reached law enforcement. After Marvin blocked a robot following a flu shot appointment, police officers arrived in response to a criminal mischief report. When she refused to move, asserting her constitutional right to protest corporate incursions in public areas, three officers handcuffed her and issued a citation for disorderly conduct on the rationale that she was blocking a business. Marvin, whose academic research examined how society adapts to new technologies, is currently waiting for her court date and intends to vigorously contest the charges.
