Meet Moxi 2.0: The Hospital Robot That Learns on the Job
Diligent Robotics is rolling out its upgraded delivery robot to U.S. hospitals. It thinks faster, runs longer, and gets smarter with every shift.
Key points
- Diligent Robotics began rolling out Moxi 2.0 to U.S. hospitals in 2026, after first revealing the robot in October 2025.
- Moxi 2.0 processes its surroundings 10 to 15 times faster than its predecessor, thanks to upgraded onboard computing chips.
- The robot can run for up to 9 hours on a single charge and charges 30% faster than before.
- Diligent was acquired by sidewalk delivery company Serve Robotics in January 2026 for $29 million.
- Children's Hospital Los Angeles says its Moxi robots have completed more than 40,000 deliveries, saving staff over 16,000 hours of transport work.
Nurses spend a surprising chunk of their shifts walking. Fetching supplies, ferrying medication, pushing carts between floors. It is necessary work, but it is not the work they trained for. Moxi, a delivery robot made by Austin-based Diligent Robotics, has been handling those runs in more than 25 U.S. hospitals for the past five years. Now the company is rolling out a significantly smarter version.
Moxi 2.0 started reaching health systems this year, with early deployments at Endeavor Health Edward Hospital, Providence Saint John's Health Center, and Children's Hospital Los Angeles.
What is actually new here?
The biggest change is speed of thought. Moxi 2.0 uses upgraded NVIDIA-powered computing hardware that perceives and processes its surroundings 10 to 15 times faster than the original robot. That matters in a busy hospital corridor, where a door swings open, a bed rolls out, and a group of visitors rounds the corner all at once.
The first Moxi often moved cautiously to stay safe in those situations. The new version can reason about the chaos in real time and keep moving with more confidence, says CEO Andrea Thomaz.
Here is a quick look at the headline upgrades:
| Feature | Moxi 2.0 |
|---|---|
| Perception speed | 10 to 15x faster than gen 1 |
| Max runtime per charge | Up to 9 hours |
| Charging speed | 30% faster |
| Daily operating hours | Up to 18 hours |
| Onboard compute increase | 10x |
| Deliveries at CHLA to date | 40,000+ |
Diligent also redesigned the robot's storage drawers and handles based on feedback from nurses and pharmacy teams, so staff can grab what they need without wrestling with the machine.
What is a "learning flywheel" and why does it matter?
Think of it like this: every time any Moxi robot encounters a tricky situation in any hospital, that experience feeds back into a central AI model, a kind of shared brain for the whole fleet. The model learns, improves, and the next software update makes every robot a little better. Diligent calls this its "learning flywheel."
The company built this cloud system with Amazon Web Services and trained the underlying model using Amazon SageMaker HyperPod, a platform for large-scale AI training. T-Mobile for Business helped make sure Moxi stays connected across hospital buildings, which are notoriously patchy for wireless signals. Crucially, all safety decisions happen onboard the robot itself, so it can still complete a delivery even if the Wi-Fi drops.
What does this mean for hospital staff?
For nurses, the pitch is simple: less time pushing carts, more time with patients. Omkar Kulkarni, Chief Innovation and Transformation Officer at Children's Hospital Los Angeles, put a real number on it. His team's Moxi robots have logged more than 40,000 deliveries, representing over 16,000 hours of transport work that staff did not have to do. The hospital has since grown its Moxi fleet from two robots to three.
Moxi 2.0 also requires no building work or IT overhauls to install, which removes one of the usual objections hospitals have to new technology.
Diligent, first reported on by The Robot Report, is now taking orders from health systems wanting to add the platform.
Common questions
Does Moxi replace nurses?
No. Moxi handles logistics: moving supplies, medications, and equipment between locations. Clinical care stays entirely with human staff, and that is by design.
Is the robot safe around patients and visitors?
All safety and navigation decisions run directly on the robot, not through a remote server, so Moxi keeps working and keeps avoiding people even if the hospital network goes down.
Who owns Diligent Robotics now?
Serve Robotics, a company that makes sidewalk delivery robots, acquired Diligent in January 2026 for $29 million. Diligent continues to operate its hospital business under that parent company.
