Products: n/a. Risk band: Elevated RobotRisk index 26.8/100 (incidents/exposure, time-weighted) · 100th percentile of 16 sidewalk delivery companies.
Serve Robotics has the largest event count in this set: five entries from September 2025 through May 2026, comprising two injuries, two crashes, and one disruption. Severities range from 1 to 4, with the highest-severity entry a May 11, 2026 lawsuit following a delivery robot collision that left a New Jersey cyclist with a broken shoulder; other entries include collisions with a mobility-scooter user with cerebral palsy, a CTA bus shelter, and an incident where a delivery cart blocked a fire truck. The index of 29 and 100th percentile ranking reflect both the highest event count and a recurring failure mode centered on collisions with pedestrians, cyclists, and mobility-device users in shared public right-of-way. The eight-month span across five events indicates a sustained pattern within the sidewalk-delivery category rather than an isolated incident, and the record is press- and litigation-driven rather than regulator-initiated.
