After $7.5M Lawsuit, Whittier Deploys Robots to Scan 400+ Miles of Sidewalks

Residents across Whittier are beginning to notice small, tracked robots moving along sidewalks at walking speed—quietly scanning pavement, curbs, and walkways. The devices, known as “Dax” robots, are part of a citywide data collection program aimed at identifying sidewalk hazards and improving public safety.
According to Mayor Joe Vinatieri, the initiative is being conducted in partnership with Bureau Veritas and is designed to analyze the condition of Whittier’s extensive sidewalk network, which spans more than 400 miles.
A Citywide Survey Underway
The program is not a pilot. It is a full-scale, systematic survey that began in late 2025 and is progressing from the eastern boundary of the city westward.
As a result, the recent increase in sightings is not due to a program expansion, but rather the robots entering more densely populated areas of Whittier. Earlier phases of the survey took place in less populated sections of the city, where fewer residents would have encountered them.
The robots move at approximately walking speed and are equipped with advanced sensors capable of capturing detailed engineering data, including sidewalk elevations, cracks, slopes, and other conditions that may pose safety risks.
When a robot completes its assigned area, it may stop and enter what officials describe as a “snooze” mode. During this time, the unit uploads collected data and awaits retrieval. City officials emphasize that this is a normal part of the process and does not indicate a malfunction.
Focus on Public Safety—and Cost Control
City officials say the primary goal of the program is to identify “uplifts” and other sidewalk defects that could lead to trips and falls. However, the initiative is also being driven by a significant financial reality.
The City of Whittier recently settled a sidewalk-related lawsuit for approximately $7.5 million, highlighting the growing cost of infrastructure-related liability.
According to the Mayor, claims and associated costs have increased dramatically in recent years:
2019: Approximately $500,000
2025: Approximately $5,000,000
These rising costs have placed pressure on the city’s budget, with officials indicating that funds spent on claims and insurance could otherwise be used for public services.
By collecting comprehensive data on sidewalk conditions, the city aims to better prioritize repairs, reduce hazards, and ultimately limit future liability.
What Happens Next
Once data collection is complete, city staff will analyze the information and develop a plan to address identified problem areas. This is expected to guide future sidewalk repair efforts and infrastructure planning.
Given the scale of the city’s sidewalk network, officials acknowledge that the process will take time.
Not Tied to the Current Election Cycle
Mayor Vinatieri also addressed potential concerns about timing, stating that the program is not connected to the current City Council elections.
The timeline supports that claim. City staff have been working with the contractor since late 2025, indicating that the initiative was underway prior to the current election cycle. Based on the program timeline, the planning and approval process likely took place in mid-to-late 2025 prior to deployment later that year.
Questions Remain
While the city has provided an overview of the program’s purpose and goals, several key details have not yet been publicly disclosed, including:
The total cost of the contract with Bureau Veritas
The funding source for the program
Whether the contract received formal City Council approval
Whether the collected data will be made publicly available
Whittier 360 News Network has requested additional information from city officials and will provide updates as more details become available.
What Residents Should Know
For now, residents can expect to see more of the Dax robots as they continue their westward progression through the city, including higher-traffic areas such as Uptown and surrounding neighborhoods.
City officials advise treating the robots with the same courtesy given to road maintenance crews. The devices are focused on infrastructure data collection and are part of a broader effort to improve sidewalk safety across Whittier.
As the program continues, its effectiveness—and cost—will likely become an important topic of discussion for both residents and city leadership.
Each robot is equipped with a QR code that residents can scan for additional information about the device and its role in the program. For those curious about the technology, the code offers a quick way to learn more about how the robots operate and what data they collect.
The Technology Behind the Program
The Dax robots being deployed across Whittier are part of a growing shift toward data-driven infrastructure management, using advanced sensor systems to collect precise engineering measurements of public walkways.
While the City has not released detailed technical specifications, systems of this type typically rely on a combination of LiDAR (Light Detection and Ranging), high-resolution imaging, and geolocation technology to map sidewalk conditions with a high degree of accuracy.
LiDAR sensors emit laser pulses to measure distances and generate three-dimensional models of the sidewalk surface. This allows the system to detect elevation changes, such as uplifts or uneven pavement, that may not be easily measured through traditional visual inspections.
In addition, onboard cameras capture detailed images of cracks, surface wear, and other visible defects. These images are paired with GPS data, allowing each issue to be precisely located and recorded within a digital map of the city’s sidewalk network.
The robots may also use inertial measurement systems to detect slope and grade changes, which can be important in evaluating compliance with accessibility standards, including requirements under the Americans with Disabilities Act (ADA).
Rather than simply recording video, the system compiles a structured dataset that can be analyzed by city staff. This data can be used to identify high-risk areas, prioritize repairs, and guide long-term infrastructure planning.
Programs like this are increasingly being adopted by cities to improve consistency in inspections, expand coverage across large networks, and create detailed records of infrastructure conditions. Those records can also play a role in reducing liability by documenting when hazards are identified and how they are addressed.
A Familiar Face for Some Residents
For some residents, the small, mobile robots have sparked a sense of nostalgia. Several community members have compared the devices to “Johnny 5,” the iconic robot from the 1986 film Short Circuit, known for its expressive movements and curious personality.
While Whittier’s Dax robots are strictly utilitarian—focused on collecting infrastructure data rather than interacting with people—the comparison highlights how their design and movement can make them appear more approachable than traditional survey equipment.
As the robots continue their westward sweep across Whittier, they are becoming not just a tool for infrastructure analysis, but a visible symbol of how technology is reshaping the way the city manages public safety and taxpayer resources.
