Chicago Sidewalk Swarm Highlights Growing Pains of Delivery Robots
By Drooid · · How we work
How the Incident Occurred
During a morning run near Lincoln Park, runner Becca Ostien encountered roughly a dozen Coco delivery robots clustered on a narrow stretch of North Clark Street. The robots’ lights flashed as they moved around one another, creating a “miniature traffic jam” that forced pedestrians to step around or pause. Coco Robotics later identified a “sidewalk deployment error” that caused multiple units to reroute simultaneously, leading to the pile-up.
Company Response and Safety Measures
Coco Robotics issued a statement acknowledging the routing error and apologizing for the disruption. The firm said its team quickly corrected the problem, clearing the robots and restoring normal operation within minutes. It added that the specific routing behavior has been solved and new safeguards have been installed to prevent recurrence. Coco also highlighted that, over two years of operation in Chicago, the fleet has completed tens of thousands of trips, saved consumers an estimated $500,000, created skilled maintenance jobs, and reduced vehicle traffic.
Accessibility and Community Concerns
The incident raised safety questions for pedestrians with mobility challenges. Commenters described the blockage as a “nightmare” for wheelchair users, and advocates noted that a temporary robot jam can become a serious obstacle for blind pedestrians, stroller-pushers, and others. Coco cited a partnership with BlindSquare, a GPS app that provides spoken alerts about sidewalk hazards in 26 languages and allows users to report cleared obstacles, aiming to improve accessibility as robots navigate public pathways.
Outlook for Urban Robot Deployments
The Chicago swarm underscores a broader tension: while autonomous delivery robots promise convenience and reduced traffic, cities must ensure that these machines do not become new obstacles on already crowded sidewalks. As fleets expand beyond college campuses into dense neighborhoods, municipalities and companies will need to demonstrate reliable routing and robust accessibility safeguards to maintain safe pedestrian spaces.
