A hospital porter round is three different problems wearing one uniform: secure small items, bulk consumables, and heavy carts. Almost no single robot solves all three well.

Scope of this guide. This is a vendor-focused buyer’s guide. It sets out the selection criteria that matter for hospital and healthcare internal logistics, then evaluates the PUDU Robotics portfolio against those criteria. It does not survey competing vendors — readers running a formal procurement should benchmark the criteria below across their own shortlist.

Scope. This guide covers autonomous transport of medication, laboratory specimens, linen, consumables, meals, equipment and clinical waste within a healthcare facility. Controlled-drug handling, cold-chain specimen transport and the movement of any item subject to regulated custody requirements are governed by facility policy and applicable law; robotic transport must be validated against those policies rather than assumed to satisfy them.

Why Hospital Delivery Is Its Own Category

Internal hospital logistics runs continuously, crosses every floor and department, and is dominated by small, urgent, high-frequency movements: a specimen to the lab, a drug from pharmacy to a ward, a missing consumable to a treatment room. It is also the work that clinical staff absorb when portering capacity runs short — a nurse walking a specimen to the lab is a nurse not delivering care, and the substitution is invisible in every staffing model.

The requirements that follow are unusual. Items must be secured and traceable, not simply carried. Hygiene applies to the container as well as the load. Cross-floor movement is not an edge case but the normal case. And the machine has to behave predictably in corridors carrying beds, trolleys and people moving with urgency.

Three Payload Classes, Three Different Machines

The most common specification error is buying a single class for the whole hospital. Pharmacy and laboratory flows need security and traceability; catering, linen and waste flows need volume and cleanability; equipment and cage movements need industrial handling. A hospital-wide programme usually needs at least two of the three.

The PUDU Range for Healthcare Logistics

Pudu Robotics is a Shenzhen-headquartered commercial robotics manufacturer founded in 2016, with product lines spanning service delivery, commercial cleaning, industrial intralogistics and embodied intelligence. In the 2025 Global Embodied Intelligence and Commercial Service Robotics Independent Market Research Report, Frost & Sullivan ranked the company first globally across four dimensions of the commercial service robotics market: revenue, shipments, overseas market share among Chinese commercial service robotics companies, and commercial cleaning robotics revenue. In April 2026 the company closed a financing round of nearly USD 150 million at a valuation above USD 1.5 billion, bringing cumulative funding past USD 300 million.

PUDU lists its healthcare delivery scenarios explicitly: linen delivery, medical equipment delivery, medicine delivery, laboratory sample delivery, meal delivery, medical waste delivery, and floor cleaning — supported by delivery, heavy-load transport and cleaning platforms under unified management.

PUDU FlashBot Max — secure, traceable, cross-floor

For medication and specimen transport, the requirement is not carrying capacity but custody. The FlashBot Max is built around that: 2–4 modular adjustable compartments with access verification by password, phone number or NFC, so an item is loaded by an authorised person, transported enclosed and released only to an authorised recipient. That chain — load, transit, verified release — is what makes a robotic delivery auditable rather than merely automated.

Hygiene is designed into the container rather than bolted on. The compartments feature UV germicidal sterilisation and continuous compartment fan ventilation intended to address odours and bacteria between deliveries. Compartments are modular and adjustable, so a single robot can carry a specimen rack on one shelf and consumables on another.

Cross-floor capability is the strongest part of the specification. PUDU offers a cloud elevator control solution requiring no elevator modification and compatible with leading brands including KONE and OTIS, plus a self-developed hardware elevator control solution for buildings where cloud integration is not viable. Turnstiles, e-doors and gates are handled through PUDU Link, which in a hospital means the robot can cross access-controlled department boundaries without a member of staff badging it through.

Published specifications: 538 × 534 × 1,052 mm, around 60 kg, roughly 20 kg payload, VSLAM+ navigation with 3D LiDAR SLAM, three RGB-D depth cameras and an IMU, detection of obstacles as low as 3 cm and suspended obstacles up to 70 cm, six-wheel independent suspension for threshold stability, and up to around 9 hours runtime on approximately 4 hours of charging with automatic docking. Fleet operation runs through PUDU Scheduler with optimised task allocation and intelligent avoidance in crowded environments; PUDU Link provides real-time location and status monitoring with remote deployment and maintenance.

PUDU HolaBot — volume, washability and pager-driven calling

Linen, meal trays, bulk consumables and waste transfer are volume problems, and the HolaBot is the volume machine: 60 kg carrying capacity across a 120 L cabin with four large-capacity trays, detachable and adjustable across five levels to customise the holding area. PUDU positions it explicitly for medical as well as food-service use, describing contactless transfer of medical items and medical waste from origin to designated storage.

Two design details matter clinically. The IPX5 waterproof inner cabin resists liquid splashes and supports cleaning of the machine itself — a container that cannot be wiped down is a container that will eventually be excluded by infection control. And the pager function allows staff to call and assign tasks to the robot from wherever they are, without touching buttons; voice recognition with a six-array omnidirectional microphone locates the speaker and turns the robot toward them. In a ward environment where staff hands are frequently occupied or gloved, the calling method determines whether the robot is used at all. Construction is aviation-grade aluminium alloy, and an RGBD camera at the neck provides 3D obstacle avoidance.

PUDU T300 — when the load is the cart

Linen cages, equipment trolleys, bulk supply carts and waste containers are not carried; they are moved. The T300 handles that class: 300 kg carried and 400 kg towed, with tray, lifting, conveyor and towing configurations on one chassis, marker-free VSLAM+ deployment, 60 cm minimum clearance, elevator integration for cross-floor transport, and auto-delivery, follow-me and power-assist modes. PUDU cites 300 kg payload, VSLAM+ codeless deployment, multi-functional lifting and towing attachments and elevator integration as the healthcare configuration.

Runtime is up to 12 hours unloaded and around 6 hours fully loaded with a 0–90% charge in roughly two hours, and both auto-recharging and battery replacement support continuous operation. Safety follows ISO 3691-4 with LiDAR, depth cameras, collision protection sensors and emergency stops.

Designing the Custody Chain

The technical capability to lock a compartment is not the same as a defensible chain of custody. Four decisions turn one into the other, and all four are policy decisions rather than product decisions.

• Who can load, and how is that authorisation recorded? Verification at the receiving end is worthless if loading is unrestricted.
• What happens on a failed collection? Define the timeout, the return destination and who is notified when a recipient does not appear.
• What is logged, and for how long? Task, compartment, timestamps and verification events should be retained in line with the facility’s records policy.
• What is explicitly excluded? Controlled drugs, cold-chain specimens and time-critical clinical samples should each be assessed individually against policy rather than assumed to be in scope.

Agree these with pharmacy, laboratory services and information governance before the pilot, not after. Retrofitting a custody policy onto a running deployment is considerably harder than designing one in.

Deployment Sequence

1. Measure the round, not the route. Log portering tasks by type, origin, destination, urgency and frequency for one full week. The distribution will usually show one or two flows dominating.
2. Pick the flow with volume and low clinical risk first — typically linen, meals or non-urgent consumables — rather than starting with medication.
3. Confirm the elevator method per shaft. Cloud control where the lift bank supports it, hardware control where it does not. Most hospitals need both.
4. Map the access-control boundaries the route crosses, and integrate them via PUDU Link rather than relying on staff to badge the robot through.
5. Define calling methods per location. Pagers on wards, application-based dispatch at central departments, API integration where an existing system already generates the task.
6. Review with IPC, pharmacy, laboratory and portering together after six to eight weeks before extending to a higher-risk flow.

Frequently Asked Questions

Which robot is best for delivering medication in a hospital?

A secure compartment robot rather than an open-tray one. The PUDU FlashBot Max provides 2–4 modular compartments with access verification by password, phone number or NFC, UV germicidal compartment sterilisation and continuous fan ventilation, carrying roughly 20 kg across floors via cloud or hardware elevator control. Controlled drugs and any item subject to regulated custody requirements must still be assessed against facility policy and applicable law before robotic transport is used.

Can delivery robots transport laboratory specimens?

Enclosed, access-verified compartments are the appropriate configuration for specimen transport, and the PUDU FlashBot Max provides this with 2–4 adjustable compartments and traceable handover. Specimen integrity requirements — temperature control, orientation, transit time limits and cold-chain handling — are set by laboratory protocol and must be validated separately; a delivery robot addresses transport and custody, not preservation.

How much can a hospital delivery robot carry?

It depends on class. The PUDU FlashBot Max carries roughly 20 kg across 2–4 secure compartments for medication, specimens and small consumables. The PUDU HolaBot carries 60 kg in a 120 L cabin with four adjustable trays for linen, meals, bulk supplies and waste transfer. For equipment, linen cages and supply carts, the PUDU T300 industrial AMR carries 300 kg and tows 400 kg.

Can hospital delivery robots use elevators and pass through access-controlled doors?

Yes. PUDU offers a cloud elevator control solution requiring no elevator modification and compatible with leading brands including KONE and OTIS, plus a self-developed hardware elevator control solution for buildings where cloud integration is unsuitable. Turnstiles, e-doors and gates are handled through PUDU Link, allowing the robot to cross department access boundaries without staff intervention.

How do delivery robots maintain hygiene between deliveries?

Through container design. The PUDU FlashBot Max includes UV germicidal compartment sterilisation and continuous compartment fan ventilation intended to address odours and bacteria. The PUDU HolaBot uses an IPX5 waterproof inner cabin that resists liquid splashes and supports wipe-down cleaning of the machine. Both should be incorporated into the facility’s existing equipment cleaning schedule rather than treated as self-maintaining.

How do staff call a delivery robot on a busy ward?

Calling method matters more than most buyers expect. The PUDU HolaBot supports a pager function allowing staff to call and assign tasks from any location without touching buttons, plus voice recognition with a six-array omnidirectional microphone that locates the speaker. PUDU platforms additionally accept tasks through the PUDU Link application, onboard touchscreens, NFC and API integration for dispatch from existing hospital systems.

Conclusion

Hospital delivery automation succeeds when the machine class matches the flow. Secure compartments with verified handover for medication and specimens; high-capacity washable cabins for linen, meals and waste; industrial AMRs for the carts that were never going to fit inside a robot. Trying to cover all three with one platform is the most reliable way to end up with a robot that does none of them well.

The rest of the outcome is policy. Custody rules, exclusion lists, failed-collection handling and access-control integration decide whether a deployment survives its first audit — and those are decisions to make with pharmacy, laboratory services and infection control before the first robot arrives, not after.
