Welcoming Diligent Robotics: Bringing Our Autonomy Platform Into Hospitals

While much of the conversation around physical AI focuses on what might be possible someday, we’ve always focused on what is already working: robots operating in the real world, alongside people, in places that demand reliability every day.

That’s what we have built on city sidewalks. And that is why I am excited to share that Serve has completed its acquisition of Diligent Robotics, the maker of Moxi, an autonomous hospital robot assistant.

Moxi supports nurses by handling routine deliveries such as supplies, lab samples, and medications, freeing them to spend more time with patients.

This is a clear next step in our evolution. We have proven we can deploy robots safely and reliably at scale in complex urban environments. Now we are extending our autonomy platform beyond sidewalks and into one of the most high-impact settings for robotics: hospitals.

Diligent is a meaningful addition to Serve. It broadens our market opportunity beyond last mile delivery into indoor settings, and it brings one of the largest commercial deployments of mobile manipulation robots working alongside people. Moxi is deployed in over 25 hospital facilities across the U.S. and has completed more than 1.25 million autonomous deliveries!

What drew us to Diligent is how closely their approach mirrors ours. Their team has spent years deploying robots in live clinical settings, learning what actually works when robots need to fit into existing workflows without getting in the way. That real-world operating discipline matters.

Deploying robots in human spaces demands a particular kind of engineering: safe, reliable, and unobtrusive. Hospitals have zero tolerance for unreliable systems, which is exactly why autonomy in this environment matters. Both Serve and Diligent have built and commercialized autonomous systems that run in complex, dynamic environments and fit into everyday workflows. In hospitals, that means navigating among people, operating doors and elevators, and adapting to a new range of edge cases without getting in the way.

Hospitals add a powerful new dimension to Serve’s Physical AI flywheel: dense, confined, human-centric, multi-level spaces with new edge cases that push our autonomy to get better. Over time, our goal is simple: one autonomy stack, one data flywheel, and one operating system for robots that work alongside people whether it is out on city sidewalks, or inside buildings and critical institutions. That’s how autonomy becomes infrastructure, and how physical AI moves from hype and promise, to something that quietly delivers real value to people everyday.
