ARCHITECTURE

Hospital Physical AI Layered Architecture

L37 turns robot deployment from a multi-year risk into a validated rollout. Our hospital digital twin platform spans Layers 1–4, integration, simulation, decision-making and supervision, so you validate in simulation before you commit capital to the floor.

WHY L37

A digital twin built for healthcare,

not adapted to it

Regulatory pressure on healthcare robotics is tightening through 2026–2027, yet no off-the-shelf, healthcare-native, regulator-ready twin exists.

Today's three options

Build in-house

A multi-year, multi-disciplinary build, and it still ages.

Buy generic tools, used raw

Powerful engines, no clinical content, no validation, no hospital library.

Skip simulation

Train on production patients, slow, risky, non-compliant.

VS

L37 — a fourth option

Healthcare-native

Clinical workflows, infection-control zones and equipment taxonomies pre-modelled.

Ontology-led

A knowledge graph binds every asset, zone and workflow to meaning a robot can reason over.

Evidence packaged

Signed Validation Report with every twin — Quality Index and V&V40-aligned evidence.

Built to operate

One subscription spanning capture, simulation, validation and live supervision.

HOW IT WORKS

From hospital floor to a validated digital twin, in five phases

L37 collapses a multi-vendor, 18-month build into a single repeatable pipeline, delivered as a subscription and signed off with a validation report.

/01

Physical capture

We scan the facility to millimetre accuracy, capturing every room, corridor and fixed asset exactly as built.

/02

Clean & structure

The raw scan is cleaned, aligned and automatically sorted into recognisable rooms, equipment and zones.

/03

Building model

The scan becomes an accurate, editable building model that plugs into your existing CAD and BIM systems.

/04

Physics & realism

Real world physics, including weight, friction, materials and lighting, are applied so the twin behaves like the building, not just looks like it.

/05

Validation & go-live

Robots and clinical workflows are trained and stress-tested in the twin, then signed off with an auditable validation report before anything reaches a patient.

WHY IT GENERALISES

More than geometry:

a Clinical Knowledge layer

A photorealistic twin is geometry. L37 binds that geometry to a clinical-operational ontology held in a knowledge graph, so every object, zone and workflow carries meaning a robot can reason over.

An infusion pump is no longer just a mesh. It becomes a clinical asset with a function, a location, an infection control class and a clinical context.

/01

Objects carry meaning

Function, taxonomy, zone and clinical context — not just shape.

/02

Actions map to care

The same ontology links a validated robot task in sim to the real clinical workflow it serves.

/03

Engine-agnostic

The knowledge graph travels with the twin regardless of OEM or runtime.

ROI

Lower total cost, faster to value, no team to build

Building a hospital twin in house is a multi year project with scarce talent, heavy upfront investment and constant upkeep as the facility changes. A subscription delivers the same twin in weeks, at the level of detail your robot programme needs, and keeps it current.

SIM-TO-REAL VALIDATION

Every twin ships with

auditable evidence

Before you rely on what the twin tells you, we prove it matches your real facility. Every twin ships with a signed validation report, an auditable record of how closely simulation reflects reality, structured to support your robot partners' regulatory work, never to overstate it.

/01

Core task battery

What we test

A standard suite of navigation, manipulation and handover tasks run across the full twin before any robot goes near a patient.

/02

Sim + real

How we prove it

Each validated task is mirrored on real hardware in a matched physical environment so simulation accuracy is measured, not assumed.

/03

Measured

A score, not pass/fail

Task success rate, trajectory deviation, reaction to clinical interruptions and edge cases are all logged and scored against acceptance criteria.

/04

Varied Conditions

Real variation built in

Lighting changes, patient equipment, staff presence and surge layouts are applied systematically so the twin proves robustness, not just baseline performance.

FAQ

The questions hospitals and clinics ask first

If yours isn't here, ask us directly; we answer every question in detail on request.

Robots, automation and complex workflows carry risk. A digital twin lets you simulate, train and validate everything in a photorealistic replica of your facility before anything operates near patients. It cuts the time and cost of change management, reduces the chance of incidents, and gives you a persistent asset you can use for planning, staff training and regulatory evidence long after go-live.

The physical capture phase requires access to your facility, but it is designed to be done in short windows, after hours, or in unoccupied areas. Most hospitals complete capture in two to four days. After that, the twin exists entirely in software, so ongoing work is invisible to your staff and patients.

No. L37 delivers and maintains the twin as a managed service; you do not hire simulation engineers, buy licences or build infrastructure. Your team interacts through a dashboard and review sessions. We handle updates as your facility changes.

You own your facility data. L37 processes it under a data processing agreement, stores it in encrypted, access-controlled infrastructure, and never uses it to train models or share it with third parties. We can work within your data residency requirements for most major regions.

For most Foundation and Navigator customers, the twin is live and usable within eight to twelve weeks of contract signature. The first Validation Report typically follows within two weeks of twin delivery. Enterprise engagements with surgical robotics or complex regulatory evidence may run to sixteen weeks.
