Delivery robots swarm Chicago sidewalk in viral video

You expect traffic jams on Chicago streets. You probably do not expect one on the sidewalk caused by a bunch of food delivery robots. That is exactly what runner Becca Ostien encountered near Lincoln Park. At least a dozen Coco delivery robots had gathered along North Clark Street, leaving her to navigate what looked like a miniature robot traffic jam.

The strange scene quickly spread online. Yet behind the viral video sits a bigger question about the growing number of delivery robots rolling through American cities. What happens when the technology designed to make deliveries easier starts getting in your way?

UBER EATS DRONE DELIVERY COULD SOON REACH YOUR HOME

Ostien regularly travels through the area near Lincoln Park. During a recent morning outing, she came across a group of Coco robots clustered together on the sidewalk. Some appeared to be trying to maneuver out of the group. Others remained stationary.

Ostien described the robots as "swarming" and said someone without agile feet would have had trouble getting through. Video of the encounter shows roughly a dozen robots packed into a narrow stretch of sidewalk. Their lights flashed as they moved around one another with nowhere obvious to go.

That may look funny for a few seconds on social media. For someone who depends on a clear pedestrian route, the situation can become far more serious. One commenter described the scene as "an actual nightmare" for a disabled person. Other reactions raised concerns about people using wheelchairs or walkers trying to get through.

Coco Robotics acknowledged the problem and apologized. In a statement to CyberGuy, Coco said a "sidewalk deployment error" caused several robots to reroute at the same time as they left their station to begin their daily routes.

"That's not how our robots are designed to operate, and we understand the disruption it caused," Coco told CyberGuy. The company said its team identified and corrected the problem quickly, clearing the robots and returning them to normal operation within minutes.

"We've since solved the routing behavior that led to this and added safeguards to prevent it from recurring," the company said. Coco called the situation rare and said it has completed tens of thousands of trips during its two years operating in Chicago.

The company also estimates those deliveries have saved consumers roughly $500,000, created skilled fleet-maintenance jobs and reduced vehicle traffic.

ROBOT DOG COULD DELIVER YOUR NEXT PACKAGE AND AN AD

The Lincoln Park pileup did not happen in a vacuum. Delivery robots have been operating in Chicago through a pilot program, and the rollout has already faced resistance from some residents.

Petitions have called for the city to pause the program. There have also been documented crashes involving delivery robots and bus shelters.

Those incidents help explain why another viral robot problem can quickly trigger frustration. The technology offers an obvious convenience. A small autonomous machine can handle short food deliveries through a neighborhood.

However, city sidewalks already have plenty of competition for limited space. Adding autonomous machines raises questions about how much room they should get and what happens when their navigation systems fail.

The bigger issue is pedestrian access. Public sidewalks need to work for people with very different mobility needs. A cluster of robots can narrow or block the path for someone using a wheelchair or another mobility device. A blind pedestrian may have difficulty navigating an unexpected obstruction. Parents pushing strollers can face the same problem.

For someone who cannot safely step around a robot or leave the sidewalk, a temporary blockage can become a serious obstacle. Coco says it is also working on accessibility through a partnership with BlindSquare, a GPS app for people who are blind or partially sighted.

The partnership operates in Chicago and other cities. According to Coco, its robots log sidewalk hazards such as fallen e-scooters and broken curb cuts. That data flows into BlindSquare, which provides spoken alerts in 26 languages about hazards roughly 10 meters ahead.

Coco says BlindSquare users can also report when an obstacle has been cleared, allowing the company to update its routing maps in real time. "Robots built to navigate the pedestrian environment have a responsibility to improve it for everyone who shares that space," Coco told CyberGuy. The partnership adds important context to the accessibility concerns surrounding delivery robots.

However, the Chicago incident also underscores the challenge: the robots themselves cannot become another obstacle on the sidewalk. That makes preventing deployment and routing failures especially important as these fleets expand.

Delivery robots are becoming more common in public spaces. We have already seen companies push these machines from college campuses toward grocery delivery and busy city neighborhoods. That means more people could soon encounter autonomous robots during an ordinary walk.

For consumers, convenience remains the appeal. You order lunch and a robot brings it down the sidewalk. But cities also have to decide how these machines fit into crowded pedestrian spaces. A successful system has to account for people who cannot simply step around a stalled robot or squeeze through a narrow gap. One strange Chicago morning gives us a pretty good preview of the challenge.

WHAT HAPPENS IF THE WAYMO COMPUTER FAILS?

Delivery robots could become a normal part of getting food and packages around crowded cities. I can see why companies are investing in them. They could make some short deliveries quicker and keep another car off the road.

Coco's response adds important context. The company says this was a rare routing problem, that it has fixed the behavior behind it and that new safeguards are in place. I also find the BlindSquare partnership interesting because Coco's robots are already moving through the same sidewalks where accessibility hazards can create real problems.

Using those robots to identify obstacles could be genuinely useful. But the Chicago pileup also shows why reliability has to come first. A robot that warns someone about a blocked sidewalk cannot become the thing blocking that sidewalk. As more of these machines appear in cities, companies will have to prove that their safeguards work when something unexpected happens. People should not have to compete with delivery machines for a safe route down the sidewalk.

Would Coco's response and its work with BlindSquare make you more comfortable having delivery robots in your neighborhood, or do you still think they should stay off sidewalks? Let us know by writing to us at Cyberguy.com.
