Diligent Robotics

What Diligent Robotics does

Diligent Robotics is/was a healthcare-focused physical-AI company that builds mobile hospital service robots designed to assist clinical staff with routine, non–patient-facing tasks. Its flagship robot, Moxi, is intended to reduce interruptions to nurses and other care team members by autonomously delivering items such as medications, lab samples, and supplies, while learning and adapting to hospital workflows through human-guided learning. The company’s autonomy approach emphasizes operating safely and reliably in dense, unstructured indoor environments (e.g., navigating crowded hospital spaces and interacting with humans during day-to-day care delivery).

As of January 27, 2026, Diligent Robotics became a wholly owned subsidiary of Serve Robotics (Nasdaq: SERV) following Serve’s acquisition of Diligent. Serve stated that the deal extends its autonomy platform into indoor environments and hospitals, and that Diligent will continue operating as a subsidiary under Andrea Thomaz’s leadership.
