How Autonomous Mobile Robots Can Benefit Clinical Laboratories

How can autonomous mobile robots for clinical laboratories help?

Autonomous mobile robots for clinical laboratories take over the carrying work that pulls technicians away from testing. A lab moves specimen racks, reagents, consumables and completed work between receiving, processing and storage many times a shift. An autonomous mobile robot, or AMR, carries those loads on repeatable routes, so people stay at the bench or the analyzer.

The main job is sample transport. When a robot handles the trips between receiving and the lab, technicians stop acting as couriers, and the minutes they used to spend walking go back into testing, quality checks and result review. The gains are biggest on busy shifts, when the walk is longest and the bench is most crowded.

This page covers the staffing problem, how a robot runs a shift, the areas it works in, how it fits alongside your team, what drives the savings, what it cannot do, and how to get started. Robot lease options come through financing, and the lease is quoted after a free site assessment.

What staffing problem are clinical labs facing?

Clinical laboratory technologists and technicians held about 351,200 jobs in 2024, according to the U.S. Bureau of Labor Statistics. The bureau projects about 22,600 openings per year on average over the decade, even though employment growth is limited. For an operator, that means open roles are hard to fill, and each unfilled shift lands on the people still working.

The ASCP 2024 Vacancy Survey, published in the American Journal of Clinical Pathology, found vacancy rates had fallen from the 2022 survey but remained above pre-pandemic levels. Anatomic pathology had the highest vacancy rate at 28.5%, and cytogenetics had the lowest at 7.7%. The survey gathered responses from 1,027 laboratory leaders and HR professionals, covering staffing data for 18,626 laboratory employees.

Turnover adds to the pressure. A turnover report cited in a February 2025 trade article puts medical laboratory technologist turnover at 15.9%, among the highest in the hospital. That figure reflects 2023 data, and ASCP reports that retirement rates are accelerating across most laboratory departments.

Where does technician time go during a shift?

Much of the walking in a lab is not testing. Specimens arrive at receiving, move to processing, then go to storage, while supplies travel the other way. Each leg is short, but a shift stacks many of them on top of work that needs a trained person.

One hospital trial from 2007 to 2008 offers a rough sense of the problem. A trade article on that specimen robot trial reports that some administrators estimated up to four hours per 24-hour shift rotation went to carrying specimens between receiving and the lab. That was an estimate of the problem rather than a measured saving, and the trial is nearly two decades old.

The walk is a measurable line item, and it is the part of the workday most easily moved onto a route that repeats. The first question for any site is how many of those trips happen each shift, and the site assessment is built to count them.

How does an autonomous mobile robot run a shift in the lab?

Before go-live, the robot is mapped through the building and the routes between the points the lab uses, such as receiving, processing and storage. Staff call the robot to a department, load the rack or bin, and send it to the next point. The robot follows its pre-mapped path, so the route is known before the first run.

The robot does not decide what goes where. Lab staff set priorities and keep custody of every specimen, and the robot only moves the load. When a route is blocked, the robot stops and waits, so a person can clear the way.

Over a shift the same loops repeat. Collected specimens go from receiving to processing in the morning, supplies come from storage to the bench at midday, and finished work goes back to storage in the afternoon, all on paths the robot already knows. That repetition is what makes transport a good fit for a robot.

Which areas of the lab does the robot work in?

Clinical labs have several zones with clear handoffs, and an autonomous mobile robot fits best where the trip repeats, the route is stable and the load is predictable. According to a CMS laboratory statistics document, 301,284 laboratories are registered under CLIA, so this workflow is common across the country.

The six areas below are common in lab floor plans. The exact set depends on the site, and the mapping step checks each route against shared hallways, doors and other traffic before any robot runs a load.

How does the robot work alongside existing staff?

The robot is not a replacement for the team. It takes over carrying, so the people already on staff spend their time on tasks that need training, such as testing, quality checks and result review. A lab still needs technologists, technicians and supervisors on every shift, and the plan is a robot working beside a team, never a lab run without people.

Staffing changes should be planned with the lab leader rather than assumed. The useful question is which hours of carrying go away, and where those hours return. Those answers come from the routes on your own floor, not from a generic average.

Staff also need to trust the robot. Training on the call process, the load limits, and what to do when a route is blocked usually decides whether the robot gets used or worked around.

What drives the savings in hours?

Savings come from hours of carrying and walking that move back to lab work. The main drivers are how many trips a shift has, how long each one takes, and how many can follow a fixed route. A site with many repeated legs gains more than one with a few long ones.

The most specific figures come from vendor case pages, and their baselines are not always stated. According to the vendor case page, one hospital in Spain saw the robot save staff about 2.5 hours per day in the first weeks by taking over courier runs, with the sample size unclear. A second lab automation vendor reports 18,965 staff hours saved across 7.15 million samples transported, with the period not stated.

Taken together, the reported time at stake runs from about 2.5 hours per day in one vendor case to up to four hours per 24-hour shift rotation in the older hospital estimate. Neither is a promise. No independent time-motion study with measured technician hours saved was found, so the trip count on your own floor is the only reliable baseline.

What can the robot not do?

An autonomous mobile robot moves loads on routes. It does not run assays, load or unload analyzers, or decide which specimen is urgent. It can only carry loads it was set up for, on routes that were mapped.

It is also not a fix for a broken workflow. If specimens sit at receiving because processing has no open bench, a robot will carry them faster to the same queue. The lab's process has to work before the robot can add value.

Routes can be blocked, and a power or network interruption can also stop the fleet, so the site plan should cover manual transport on the days a robot is out of service. Service is provided nationwide, but the lab keeps its own backup plan for the bench.

How do you get started with a robot lease?

Start with a free site assessment. We map the routes, count the trips that matter, pick the robot that fits the floor and identify the transport tasks with the most repeated work. As a US commercial robot integrator, we also handle deployment and integration, train your staff and provide service nationwide.

The robot is leased through financing, and the payment comes in the quote. The quote follows the site assessment, so you can compare robot lease options against the trip data from your own floor before you decide.

Deployment can be phased, starting with one robot on the most repeated route, then adding routes as staff confirm the time saved. Go-live support, training and remote triage with on-site dispatch keep the first weeks steady.
