The ride-hailing giant and its former subsidiary are clashing over how to deploy sidewalk delivery robots, threatening Uber's broader autonomous ambitions. Uber and Serve Robotics, the sidewalk delivery robot company it once incubated, are heading for a breakup. AdvertisementThe partnership was straightforward on paper: Serve would deploy up to 2,000 delivery robots on the Uber Eats platform, handling last-mile deliveries in urban areas. Eduardo Rojas, a former member of Uber’s Autonomous Mobility & Delivery team, disclosed the deteriorating situation in a LinkedIn post. In January 2026, Serve acquired Diligent Robotics, pushing the company beyond sidewalk delivery into indoor robotics solutions with applications in healthcare, hospitality, and logistics.
