Diligent Robotics Moxi

Commercial Medical · #5
Index score 82.2 (#24 overall) · Roughly 100 robots deployed across 25+ US hospitals; acquired by Serve Robotics in early 2026, with the upgraded Moxi 2.0 rolling out from August 2026. · Last verified 2026-09-01

Moxi is a hospital logistics robot from Austin-based Diligent Robotics, now a Serve Robotics company, that autonomously delivers medications, lab samples and supplies so clinical staff don't have to. Nearly 100 robots operate in more than 25 US hospitals and have completed over 1.25 million deliveries. The upgraded Moxi 2.0, unveiled in October 2025, began rolling out in August 2026. It is a service robot, not a surgical device.

  • One of the largest commercial fleets of AI-powered mobile manipulation robots operating in human-centric environments, per Diligent [source]
  • Acquired by Serve Robotics in a deal announced January 20, 2026 (~$29M in stock plus up to $5.3M in milestones) [source]
  • Moxi 2.0 rollout began August 2026 at Endeavor Health Edward Hospital and Children's Hospital Los Angeles [source]

Our take

Moxi addresses hospitals' most quantifiable pain point, staff time lost to fetch-and-carry, and its mobile-manipulation approach (an arm that can press elevator buttons and hand off items) distinguishes it from cart-style robots like Aethon's TUG. The RaaS model keeps capital cost low but is a recurring expense. The Serve Robotics acquisition brings scale and physical-AI investment; the open question is how well a sidewalk-delivery parent sustains a healthcare sales motion.

Best suited for

  • Medication and lab-sample delivery between pharmacy, lab and nursing units
  • Supply and equipment runs on inpatient floors
  • Reducing non-clinical walking time for nurses

Moxi: common questions

How much does a Moxi robot cost?
Diligent sells Moxi as a robots-as-a-service subscription rather than a one-time purchase; press reports cited expected revenue of roughly $200K-$400K per hospital per year. No unit price is published.
What does the Moxi robot do in hospitals?
It autonomously delivers medications, lab samples, supplies and equipment between departments, navigating hallways and elevators, so nurses spend less time on fetch tasks. It does not perform any clinical or surgical care.
How many hospitals use Moxi?
Around 100 Moxi robots operate across more than 25 US hospital facilities, with over 1.25 million deliveries completed.
Who owns Diligent Robotics now?
Serve Robotics, the publicly traded sidewalk-delivery robot company, agreed to acquire Diligent in January 2026 for about $29 million in stock plus up to $5.3 million in milestone payments.
What is new in Moxi 2.0?
Ten times the onboard compute of the original (via newer NVIDIA Jetson hardware) and platform improvements aimed at running 15 or more robots per hospital. Rollout to health systems began in August 2026.
