Delivery robots are increasingly sharing pavements with pedestrians, but their growing presence has raised questions about employment, public safety, and shared-space priorities. In Philadelphia, one woman's protest has escalated these issues into a legal dispute.
Carolyn Marvin, a 78-year-old retired University of Pennsylvania communications professor, was arrested on 14 October for deliberately blocking an Uber Eats delivery robot in Center City. The incident occurred near the 1200 block of Filbert Street, where she refused to allow the robot to continue its route.
Philadelphia police responded at approximately 1:16pm to a report of criminal mischief. When officers arrived, they instructed Marvin to move several times. However, her refusal to comply led police to issue her a criminal violation notice for disorderly conduct.
'I Wasn't Impeding Any Persons'
Marvin's arrest drew attention to her months-long campaign against autonomous delivery machines. She considers them an increasingly intrusive presence in public spaces. In an interview with CNN, she questioned why blocking a robot led to police intervention. She believed her actions were protected as a form of protest.
'I was under the impression that I had more rights than the robot did,' Marvin said. 'I wasn't impeding any persons. I was impeding a machine.'
Her objections focus on three main concerns: potential loss of low-wage delivery jobs, pedestrian safety, and privacy risks from cameras in the machines. She also believes public spaces should stay accessible to people, rather than increasingly accommodating corporate technology.
Marvin estimates that her demonstrations typically delay deliveries by 10 to 15 minutes. Although she acknowledges the disruption, she sees it as a small price to raise awareness of automation's broader implications.
The Need for High-Trust Societies
In March 2026, Uber Eats launched its autonomous delivery service in Philadelphia, deploying Avride's delivery robots in Center City. Similar robots have also been introduced in cities including Los Angeles, Miami, Austin, and Dallas.
Marvin's protest is not the first instance of deliberate interference with delivery robots. In Los Angeles, two men attempted to steal a Serve Robotics robot by loading it onto a truck, but the machine escaped. In Sacramento, three men were filmed toppling a delivery robot and repeatedly slamming it onto the pavement.
A social media user questioned whether autonomous delivery and driving services can succeed in societies with limited public trust and wrote, 'Automated delivery and driving only work in high trust societies. We don't live in one, so unless these things have weapons like in Black Mirror they are just going to lose money.'

For Marvin, the issue highlights a broader concern about technology encroaching on spaces traditionally reserved for public use. She has also joined demonstrations for civil rights, abortion rights, and Black Lives Matter, as well as protests against the Vietnam and Gulf wars.
'I also think that I have a First Amendment right to protest the abuses of corporations in public space, in the same public space that the robots are occupying,' she told CNN. Despite her arrest, Marvin intends to continue her demonstrations. Asked whether she planned to keep blocking delivery robots, she replied, 'Oh yeah.'
Do Robots Have Pedestrian Rights?
The legal distinction in Marvin's case stems from Pennsylvania's Act 106 of 2020. This legislation classifies autonomous delivery machines as pedestrians under the state's Vehicle Code and establishes rules for their operation.
However, this status does not give them priority over human pedestrians. The law requires personal delivery devices to yield the right of way to pedestrians and pedalcyclists in such areas.
Democrats, Labour unions and accessibility advocates opposed the said legislation, citing concerns about job loss and risks to pedestrian safety. Supporters, meanwhile, viewed the technology as a way to modernise delivery services.
