Robot Named Dax Helps 5 US Cities Fix Dangerous Sidewalks

Meet Dax, the sidewalk-surveying robot that's winning hearts while saving lives across five American cities.

This summer, residents in Bangor, Maine; Hoboken, New Jersey; Hollister, California; Tyler, Texas; and Hilton Head, South Carolina noticed something unusual on their streets. A small white robot, standing just 35 inches tall and wearing a high-visibility jacket, has been cruising their sidewalks at walking pace.

Dax isn't lost. He's working.

Developed by an Oregon robotics firm, Daxbot continuously measures sidewalk gradients, widths, and vertical changes. The robot packages this data and sends it to city planners, helping them identify which sidewalks need urgent repairs.

The job might sound simple, but it solves a real problem. Finding human surveyors willing to work on black asphalt under a July Texas sun is nearly impossible. Meanwhile, cities like Hoboken and Tyler have set ambitious goals of zero pedestrian traffic deaths.

Broken sidewalks play a bigger role in safety than most people realize. When a tree root lifts the pavement or cracks make walking difficult, strollers, bikes, and scooters drift onto the road. That small shift brings them dangerously close to moving cars, and nine out of ten pedestrian traffic deaths happen on road surfaces, not sidewalks.

In Tyler, one Daxbot was even hit by a truck making a right turn at a crosswalk. The incident proved the robot's value in identifying dangerous intersections while keeping human surveyors out of harm's way.

The Ripple Effect

Hoboken Mayor Emily Jabbour sees Daxbot as part of a larger vision. "Hoboken has become a national model for street safety because we've consistently invested in making our streets work better for everyone," she said. The city is combining the robot's data with resident feedback and guidance from accessibility advocates to create truly inclusive infrastructure.

Bangor plans to deploy six robots that will each cover about six miles of sidewalks daily. That's comprehensive coverage no human team could match at the same cost.

The robot's design, reminiscent of Pixar's WALL-E, wasn't always meant for infrastructure. Daxbot originally tested its technology by delivering pizzas. Everything changed when a city planner called asking if the robot could survey sidewalks instead.

Children absolutely love encountering Dax on their streets. Several cities now encourage residents to snap selfies with the robot and share them on social media, turning infrastructure maintenance into community engagement.

One small robot is proving that smart technology can make cities safer, more accessible, and a little more joyful for everyone who calls them home.
