LUNAFORMA™ — Public Site v5

02 · System architecture

Integrated construction system

LOOM, LatticeForm, RILL and CAIRN each have a clear role. Together they form a practical path for robotic lunar construction without claiming a single machine or material can do everything.

01 / LOOM™

LOOM™

Cable-driven robotic handling across large construction areas. A lightweight support frame or distributed anchor arrangement can carry a moving tool head over the work zone.

Construction platform · concept stage

→

02 / LATTICEFORM™

LatticeForm™

A family of lightweight structural elements designed to be filled with local regolith. The cells share a common handling and connection logic.

Primary hardware family · first demonstrator

→

03 / RILL™

RILL™

Selective treatment of regolith at surfaces, joints and interfaces where additional strength, stability or wear resistance may be useful.

Research mechanism · under study

→

04 / CAIRN™

CAIRN™

Build coordination, traceability and state awareness. Over time it may also use identifiers or embedded sensing to improve what the system knows about the finished structure.

Build intelligence layer · under study

SYSTEM LOGICLOOM builds. LatticeForm structures. RILL treats selectively. CAIRN verifies.

02A · Machine studies

A machinery language for lunar construction.

These concept visuals are not fixed final machine designs. They are here to make the material flow more legible: excavation, metering, auger transfer, fill placement and selective treatment.

Public note: these visuals are moodboard-style machinery studies rather than final technical drawings.

Auger study

Controlled transfer of regolith is one of the key enabling functions for lunar construction.

Hopper study

Buffer storage can separate excavation from placement and keep the work sequence stable.

Placement head

A lightweight tool head can place or feed material without looking like terrestrial heavy equipment.

Treatment head

Selective treatment is reserved for areas that need stronger surfaces, joints or anchors.

03 · LatticeForm structural system

A common structural interface

The LatticeForm family uses a small set of compatible parts. Each part serves a different structural role while following the same basic logic for handling, placement and build-up with local regolith.

LF-100 / MASS CELL

Mass Cell

The basic building block for walls, berms and vaults. It arrives light, opens into shape and gains most of its mass after filling.

LF-120 / HALF CELL

Half Cell

A smaller piece for staggered joints, wall ends, openings and repairs.

LF-200 / WEDGE CELL

Wedge Cell

A sloped piece for berms, ejecta barriers and changes in angle.

LF-220 / RADIAL CELL

Radial Cell

A curved piece for tanks, utilities, shelters and protective vaults.

LF-400 / INTERFACE CELL

Interface Cell

A service piece for pipes, cables, sensors, equipment mounts and maintenance access.

05 · Connection grammar

A simple rule: standardize the connection, not the shape.

Like LEGO or masonry, the strength comes from repeatable connections, overlapping joints and pieces that help restrain their neighbours. The lock holds the assembly together; the geometry carries much of the load.

01 / COMMON GRID

Different pieces, familiar interfaces.

The robot finds the same grip, guide and service points across the family.

02 / LOAD PATH

Let the shape carry the load.

Seated faces, keys and rails take compression and sideways force before the final lock is engaged.

03 / DISTRIBUTED RETENTION

Use several simple locks, not one perfect latch.

Distributed engagement resists sliding, rotation and uplift while staying serviceable by robots.

04 / BOND LAYERS

Bridge the joints.

Staggered cells and spanning rails keep one joint from becoming a continuous weak line.

06 · Flagship systems

Infrastructure applications

The first useful structures are likely to protect water, power, mobility and communications—not stand alone as architectural objects. LUNAFORMA is being shaped around those real operational needs.

Robotic lunar excavation and protected utility concept

LatticeForm–FIRN Shielded Utility Vault

A protective shell built around a water reserve and utility node, using regolith for shielding and ballast while keeping service access and thermal separation.

FLAGSHIP CONCEPT · WATER RESERVE + THERMAL BUFFER + RADIATION / IMPACT SHIELDING

Lunar rover beside protected utility corridor concept

Lunar Utility Spine

A protected route for water, power, data and thermal lines between surface assets.

CIVIL INFRASTRUCTURE CONCEPT · CONNECTS WATERIG / OASIS / FIRN / FLARE / SURFACE ASSETS

Lunar construction demonstrator and landing zone concept

FLARE Haven

A protected service point for mobile lunar systems: landing or parking, ejecta control, maintenance, resources and navigation in one place.

ASSET-SPECIFIC CONCEPT · REQUIRES PLUME, DUST AND OPERATIONS VALIDATION

MoonYard Remote Construction Lab

A ground testbed where small cells, regolith simulant, robots and simulation can be tested together before larger field trials.

NEAR-TERM PRODUCT · SIMULATE → BUILD → MEASURE → COMPARE

06A · Field condition

Start with a protected operational zone.

A practical early use case is a protected work zone: utility protection, landing support, robotic servicing and bermed boundaries in one integrated patch.

Regolith-filled perimeter structures for shielding and ejecta management
A defined service edge where LOOM, hoppers and fill tools can work repeatedly
Selective RILL treatment only at the parts that need wear resistance or anchoring

Operational picture · useful for FIRN, FLARE and landing-zone discussions

07 · Engineering basis

Send the precision. Source the mass locally.

Earth provides the parts that need tight tolerances: interfaces, lightweight frames, tools, liners, sensors and electronics. The Moon provides the heavy fill. Where a joint, surface or anchor needs more performance, RILL can add local treatment instead of processing the entire structure.

“Launch the precision. Source the mass locally. Process only what needs processing.”

Core differentiator

A connected structure with standard interfaces—not a pile of independent bags.

Primary challenge

Dust, partial gravity, anchoring and repeatable locking remain the hard engineering problems.

Near-term proof

Build several shapes with one handling and locking method, then load-test them.

Commercial bridge

Use the same composite know-how in robotics, education and extreme-environment hardware on Earth.

Programme discipline: LatticeForm is complementary to sintering, landing-pad surfacing and additive construction. It is favoured where reversibility, compact transport, low process energy or rapid robotic installation matter.

08 · Industrialization

LUNAFORMA: Building Lunar Infrastructure with Lightweight Hardware and Local Mass

EURUS.SPACE · SURFACE SYSTEMS CONCEPT GROUP · AUGUST 2026

Abstract

LUNAFORMA combines four complementary ideas: LOOM moves and services construction tools; LatticeForm gives local regolith controlled shape and structural interfaces; RILL investigates selective treatment of the places that need more strength or surface control; and CAIRN keeps the construction record. Together they aim to reduce transported mass and avoid unnecessary bulk processing while enabling protected utilities, water reserves, landing-zone infrastructure and early lunar civil works. Performance remains contingent on mechanism reliability, dust tolerance, partial-gravity behavior, material durability, excavation and conveyance efficiency, RILL process physics, energy availability and integrated robotic operations.
