Sidewalk Accessibility Assessment Underway
Dax robots are assessing the sidewalks, trails, or other pedestrian facilities in this area. We create color coded maps showing the current condition of the paths we assess, which are used by cities and universities to help keep sidewalks and trails accessible and safe.
Daxbot asks motorists to show the same courtesy they would give to any road maintenance worker.
When a bot finishes its assessment area, it will go into "snooze" mode to upload data and await pickup. This is normal and does not mean there's anything wrong with the bot.

For the engineering minded, here are the instruments Dax uses to collect pedestrian facility data:
| Measurement | Measuring Device | Accuracy |
|---|---|---|
| Elevation Measurements | Keyence IL-300 Laser Measurement | 1/32 inch |
| Distance Measurements | RTK GPS System augmented with internal Tread-Based System | 1/16 inch |
| Slope Measurements | CTi TILT-57A Inclinometer | 0.03% |
| Photogrammetry | High resolution optical measurements | > 97% |
FAQs
-
The robots are designed, manufactured, and operated by Daxbot, based in Philomath, OR. Daxbot operators use the robots to collect data about city & university sidewalks.
-
No, robots are not collecting personal data. Daxbot cameras are focused on the sidewalk in front of them and are used only used to collect pedestrian facility data and aid with navigation. The only time video gets saved is in the event of a safety-related incident.
-
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, and it collects continuous measurements rather than measuring at intervals every several feet. This gives cities & universities faster, more actionable data.
-
Automated collection saves cities & universities time and money. Because the work can often be completed faster and with more detailed data, robotic collection can reduce the overall project timeline and cost compared with traditional manual methods.
-
No. The robots are a tool used to measure pedestrian facilities more efficiently and will be around just long enough to complete their work. City staff, consultants, engineers, and ADA coordinators still guide projects and make the planning decisions.
