What Are the Little Robots on Pleasanton's Sidewalks Measuring?

On a Tuesday morning in mid-September, a small wheeled robot rolled across Main Street in downtown Pleasanton against a red light. Pleasanton Weekly photographed it and noted that the robots had "taken over the streets of Pleasanton, but not in an apocalyptic fashion." Since then, people have spotted them on sidewalks and trails all over town. According to the City, you may keep seeing them through the end of the year.

The robots are Daxbots, and they're doing something Pleasanton has never done before. The City ran ADA studies of its own facilities in 2002 and 2009. This is the first full assessment of the public right-of-way, meaning the sidewalks, curb ramps, crossings and bus stops that people use every time they walk out the door. The robots are making a map, and over the next year that map will turn into a ranked list of what gets fixed first. Residents will have a chance to help shape that list.

Ground the City Has Never Measured This Way

The survey is part of Pleasanton's ADA Self-Evaluation and Transition Plan, Capital Improvement Project 16437. The City's contractor, Bureau Veritas, brought in Daxbot to collect the field data. On a typical day, 7 to 14 robots are working somewhere in the city.

The scope is large. The City's project page lists what the robots will cover:

To put that in context, the City's Public Information Officer Sharon Petrehn told Pleasanton Weekly that the robots had surveyed 13 miles as of their third day out, Wednesday, Sept. 16. That was a small start on 360 miles, which is why the work has run through the fall and will continue into December.

The sidewalk survey is one piece of a bigger review. The full ADA evaluation also covers parks, buildings, parking lots and other public spaces. The City says the data will help it decide priorities and qualify for accessibility grants.

Why the City Sent Robots Instead of a Clipboard Crew

What the robots offer is consistency, and speed is a big part of that. Daxbot's numbers, as quoted by Pleasanton Weekly, are that "a robot can measure up to 8 miles of sidewalk per day, compared with about 2 miles per day for a two-person manual crew." The company adds that a robot "collects continuous measurements rather than measuring at intervals every several feet."

Continuous measurement matters on a sidewalk. A crew taking readings every several feet can miss a raised panel lifted by a street tree between two of its stops. A robot rolling the whole length at walking speed records the full stretch. The company also says the robots keep "human crews out of traffic" while gathering data on curb ramps, signalized intersections and transit stops.

The City is clear that the robots are a data tool. They don't replace City employees, and City staff and consultants still make the planning decisions. Daxbot has run similar ADA surveys in Irvine, Whittier, Los Angeles and Hollister.

On cost, Petrehn told the Weekly that the whole Self-Evaluation and Transition Plan costs $252,000, that the robot survey accounts for about half of that, and that the work is paid for from the City's general fund.

When One Rolls Past You

If a Daxbot comes toward you on the Iron Horse Trail or outside a downtown shop, here's what the City says to expect:

• The robots generally work in daylight, between 7 a.m. and 7 p.m.
• They move at about a slow walking pace along sidewalks and pedestrian paths.
• Each one has a QR code on the front that explains what it's doing.
• You don't need to report a robot just because it's on a sidewalk, trail or other public walkway.
• They collect information about pedestrian infrastructure, not about people. The City says they don't store personal information.

When a robot finishes an area, it goes into what Daxbot calls "snooze mode." It uploads its data and waits to be picked up, according to Pleasanton Weekly. So a robot sitting still at the end of a block is most likely done for the day. If one does cause a problem, you can reach City customer service at 925-931-5500 or use the MaintStar online portal.

How the Map Becomes a Ranked List

Once the robots finish, the City says it will share results after data collection is complete, and the full Self-Evaluation and Transition Plan is expected by fall 2027.

The Bureau Veritas proposal attached to the City Council staff report lays out the steps from raw measurements to a plan:

1. A record of barriers. The field data is checked against federal, state and local accessibility standards.
2. Public input. The proposal calls for public outreach meetings and a public survey as part of the planning process.
3. Priorities. Bureau Veritas will create criteria for ranking facilities and kinds of work so improvements can be done in phases. The order follows the Department of Justice's guidance "or as modified through agreement with the City and by public survey results."
4. Price estimates. Each barrier that needs to be removed gets a rough, pre-planning cost estimate.
5. A schedule. The finished Transition Plan includes a timeline for completing the improvements.
6. A living database. The City keeps an electronic record to track each barrier as it's removed. The proposal calls this "a living Transition Plan."

Step three is where residents come in. The public survey can change the order of repairs. Someone who uses a walker on the same uneven block every day, or who pushes a stroller to the same bus stop, can help decide which barriers move up the list.

Tyler, Texas shows what the next stage looks like. Tyler's robot fieldwork ended in July 2026 after covering about 94.5 miles of sidewalks and trails, 122 signalized intersections and 59 transit stops. According to the City of Tyler's project page, the data now feeds a prioritized list of projects being built with the city's Disabilities Issues Review Board, which will go into its Transition Plan. Tyler says the timing of individual projects isn't known yet. Pleasanton has nearly four times as many sidewalk and trail miles to cover. That helps explain why its plan runs to fall 2027.

Where a Resident Fits Before 2027

The robot survey is a citywide snapshot. If you have a problem today, like a heaved sidewalk panel on your walk to Lions Wayside Park or a cracked curb ramp at the corner by your house, the City's Report a Concern page sends you to MaintStar and lists sidewalk hazards under street maintenance. The City's MaintStar guide says you can attach photos, GPS coordinates, an address and comments, and get email updates on the status of your request.

A MaintStar report goes to the City's maintenance team now. The Transition Plan is what decides the order of the bigger, citywide accessibility work, and it will be shaped in part by the public survey and outreach meetings in Bureau Veritas's scope. If you care about a particular route, you can use both: report the problem now, then answer the survey when the City opens it.

For homeowners, that route matters day to day. If you're thinking about the years ahead, the walk to the Farmers' Market or the curb ramp at the end of the driveway may matter more than the kitchen. We've covered how sidewalk issues can come up when a home sells in Sidewalks, Sewers and the Sale in Pleasanton, and the City's new survey is the most complete picture of those sidewalks it has ever collected.

If you or your parents are wondering whether your current home still works for daily life, from the front step to the end of the block, Luisi & Associates would be glad to walk through it with you, at whatever pace suits your family.
