Pediatric Corridor Floor Robots: Quiet Hours, Speed and Pauses

Can floor robots work in a children's hospital corridor?

Yes, though the conditions have to be set by the unit itself. The clearest public evidence comes from Children's Hospital Los Angeles, which has used Diligent Robotics' Moxi in its corridors since December 2022.

Moxi is a delivery robot, not a floor scrubber, so its record proves corridor navigation rather than scrubbing. A floor scrubber faces the same shared lanes, doors, carts and people. The published rules around Moxi are the closest public guide, though none of them are numbers you can copy.

What the Children's Hospital Los Angeles numbers show

Omkar Kulkarni, the hospital's chief innovation and transformation officer, said Moxi has completed more than 40,000 deliveries. He put the time saved at over 16,000 hours that staff did not spend transporting supplies and medications. The hospital reported these figures in August 2026.

The early record is smaller. CHLA's blog reported over 2,500 deliveries and 1,620 work hours in just over four months, with two robots running around the clock. At that stage Moxi was making 25 to 30 deliveries a day, about half its capacity. The chief pharmacy officer said staff recouped 20 to 30 minutes per delivery.

The fleet has grown since. According to the StreetInsider release, CHLA expanded from two robots to three, and utilization rose more than 10 percent in the second quarter. Those figures come from the hospital and the vendor, not an independent audit, so treat them as reported results.

Why a pediatric corridor is an unpredictable lane

Andrea Thomaz, Diligent's founder and CEO, describes hospital corridors as among the most dynamic settings a robot can work in. Fast moving people, doors and carts share tight spaces. A third party review says Moxi is designed for dynamic corridors, multiple floors, elevators, doors and human traffic.

A children's unit adds variables that a typical corridor does not always carry. A toddler may dart out of a playroom doorway. A child on a stretcher may travel beside a parent who is walking fast. A sibling or a family group may stop in the middle of the lane. A child's speed and direction are hard to predict, so the robot's behavior has to be built around the least predictable person in the hall.

Which rules matter most: speed, quiet hours and pauses

Speed comes first. Set a maximum speed for each zone, with the slowest settings near playrooms, bedside doors, nurse stations and any corner where a child can step out. Speed should be a zone property, not one number for the whole floor.

Quiet hours decide when the robot runs at all. Sleep periods, medication passes, procedure windows and shift changes each bring different noise and traffic. The public material has no quiet hour rules for pediatric units, so these windows must come from the unit leaders who know their patients' daily rhythm.

Pause behavior is what families actually notice. Define the triggers in advance: a person entering a set distance, a stretcher or wheelchair crossing, a door swinging open, or a group standing in the lane. Decide whether the robot resumes on its own or waits for a staff release.

What the vendor says about onboard safety and dead zones

Diligent says Moxi 2.0 runs safety and autonomy functions onboard, so tasks can finish without Wi-Fi, with cellular fallback where hospital networks have dead zones. That is a vendor claim as of August 2026. Your building has its own dead spots, so ask for a test in the exact stairwell or elevator lobby where a signal drops.

Vendor specs for Moxi 2.0 include up to 9 hours of operation at a time, 30 percent faster charging and up to 18 hours of daily operation. Diligent also says the robot operates within existing infrastructure and needs no facility modifications. Verify each claim during your pilot instead of accepting it from a datasheet.

Serve Robotics agreed to acquire Diligent in January 2026, and August 2026 reports describe that acquisition as completed. Serve says Moxi has more than 1.25 million autonomous deliveries across nearly 100 robots in more than 25 hospital facilities. These are vendor figures, and the Moxi 2.0 rollout announced August 17, 2026 includes CHLA alongside two other hospitals.

What no public source settles yet

The public material on CHLA and Diligent covers deliveries, hours, charging and corridor design. It does not publish speed limits, quiet hour schedules or pause specifications for pediatric corridors.

Any number a vendor offers for those items should be checked against your own timings and your own families' experience on the unit before it goes into a configuration.

How to test corridor rules before a full rollout

Start by mapping every corridor the robot will use, then watch it for a couple of weeks before the robot moves. Count people by hour, note stroller and stretcher traffic, and mark where families gather. That baseline shows when quiet hours belong and where zones need slower settings.

Then run one corridor, not the whole wing. Staff should ride along or shadow the first runs and log every near approach and pause. Adjust zone speeds and pause distances after each block, then move to the next corridor.

Test these scenarios on purpose:

• A child running out of a playroom doorway at close range
• A stretcher crossing an elevator lobby with a parent walking beside it
• A family group standing in the middle of the lane for an extended stop
• A network drop during a delivery near a stairwell
• A shift change with carts moving in both directions

How Service Robot Co. runs a pediatric corridor pilot

Service Robot Co. is a full service commercial robot integrator, and we are OEM neutral. We pick the robot that fits the corridor across manufacturers, then deploy, integrate, train and service it through a nationwide US engineer network. For a pediatric unit, that starts with site assessment and mapping, followed by a phased deployment that avoids shutting the corridor down.

Customers get robots through a lease. We lease robots on a three year term with one fixed payment quoted after the site assessment. Go live support and a robot maintenance service plan with remote triage and on site dispatch sit behind the lease, so the unit works with one partner and one number.
