Retired professor arrested for blocking delivery robot. Will do it again

A 78-year-old retired University of Pennsylvania professor was arrested in Philadelphia for repeatedly blocking autonomous delivery robots on sidewalks as a form of protest against their impact on delivery workers, public safety, and privacy. Carolyn Marvin says she will continue the practice, viewing it as a First Amendment-protected protest against corporate use of public space, and argues she was only delaying robot deliveries by 10-15 minutes rather than impeding people.
