Hospital Specimen Robots: Why One Unit Becomes a Fleet

What is pushing hospitals from one specimen robot to several?

Hospitals add specimen robots once a first route has shown it can carry the load. Two 2026 announcements show the pattern. In June, BayCare said it would add two Relay Robotics units, named Stork and Miles, at Winter Haven Hospital and Winter Haven Women's Hospital. In May, Arrive AI said Hancock Health would extend its autonomous network to the Parkway outpatient facility in Greenfield, Indiana.

Both are vendor announcements, not independent evaluations. The figures below are what the companies and local outlets reported, and they should be read with that in mind.

How did BayCare's Winter Haven expansion grow out of St. Anthony's?

BayCare's first robot work came in 2025 at St. Anthony's. Its June 2025 newsroom post said staff in some areas had been making between 40 and 60 trips to the lab each day. According to local reporting, the Winter Haven chief nursing officer pushed for robots after seeing the St. Anthony's units, because staff there lacked access to pneumatic tubes.

The Winter Haven plan uses two roles. Stork handles 24/7 specimen transport from Urgent Care to the second-floor laboratory. Miles bridges wings that lack pneumatic tube systems, carrying pharmacy orders and clinical supplies. Relay also reported a 2025 St. Anthony's pilot with 99.8% delivery success across 50 deliveries per day. That is a vendor-reported figure, not an independent audit.

What did Hancock Health move to Parkway?

Hancock's first robot work began in October 2025 at the Sue Ann Wortman Cancer Center, using robots from Arrive AI and Ottonomy. Its original plan cited more than a dozen daily staff trips between clinics and the hospital lab. The Parkway extension moves specimens from the outpatient draw center to the main hospital lab.

Implementation was described as expected to begin this summer, with two transport routes under evaluation. Robots drop specimens into secure lockers called Arrive Points, which hold them until staff retrieve them. That retrieval step still depends on people, so the plan should name who collects each specimen and when. Local coverage said Hancock plans to expand across a network of more than 30 locations in east-central Indiana.

What do these routes have in common?

None of these routes is exotic. They are easy to describe on a floor plan and easy to count in staff logs, which is why they expand.

• Fixed endpoints: one origin such as an urgent care or draw center, and one destination such as a lab or pharmacy.
• Repeating, time-sensitive loads that staff currently carry by hand, often several times a day.
• A physical gap the robot fills, such as a wing without pneumatic tubes or a separate outpatient building.
• Access that already works: elevator calls and badge-controlled doors the robot can use without special work.

How should the numbers be read?

The forward-looking figures are projections. Relay's Winter Haven announcement projects more than 500 deliveries per month across the two robots, and an estimated 150 clinical hours saved per month collectively. The release presents these as expectations, not measured results. Arrive AI said its system cuts the time staff spend away from patients at least in half, a company claim that a hospital should test against its own trip logs.

The most useful numbers for an operations lead are the baselines: BayCare's 40 to 60 daily lab trips in some areas and Hancock's more than a dozen daily trips. They tell you what the robot has to beat. The HCA Florida JFK deployment, which also carries specimens and pharmacy orders, reported no delivery counts in the sources reviewed for this piece.

What should an operations lead check before adding units?

Start with the route, not the robot. Confirm elevator integration, badge access for every door on the path, and where the lockable bin is loaded and received. Check lab intake hours, because a specimen that arrives at 2 a.m. still needs someone to receive it. Map the charging location and decide how a unit that goes down will be covered.

Then count the trips you already make, by route and by hour, over several weeks. Relay has described a typical hospital deployment at about 12 weeks, including integration, floor mapping and staff training, with one to two weeks onsite. Treat that as the vendor's estimate and build your go-live calendar around your own change control.

Service Robot Co. is an OEM-neutral integrator. We select robots across manufacturers, then lease, deploy, integrate, train and service each unit through a nationwide US engineer network. Our lease runs three years with one fixed payment, quoted after a site assessment that maps your routes before anyone commits.

Where is the pattern heading next?

BayCare's second robot extends work already running on its campus, and Hancock's Parkway plan moves the same kind of specimen route to a different building. The next step for many systems is copying a route template to another site, not adding more robots to the same corridor.

Copying a template only works if the first route's trip counts, hand-off steps and failure plan were written down. Without that record, a second site starts from guesses.
