INSIDE.
A MACHINE
OUTSIDE.
One dad. Cast-metal ambition.
A very real person at the center of it all.
An articulated, assisted armor project built around movement, independence, and a future augmented-reality helmet.

R46 / THE PROJECT FAMILY
One dad. One kid-scale geometry branch. One very unimpressed cat.
R46 connects the registered K2 scene back to 18 original named source files and keeps the remaining work explicit.
ADULT PROJECT
IRON-DAD
Full-size armor, support, systems, helmet, and human-first engineering.
Enter the adult project ↗ NEW / K2 R46IRON-KIDS K2
Thirty K2 source-part exports from 18 actual DaDave source files, with exact transform evidence and honest coverage limits.

Meet IRON-KITTY ↗01 / THE NON-NEGOTIABLE
THE PERSON
IS NOT THE
COMPROMISE.
You should be able to get in. Move like yourself. Get out again. The shell, the hardware, and the spectacle have to work around that.
The human-first requirements ↗02 / THREE CONNECTED IDEAS
More than a metal costume.
Separate the skin, the support, and the intelligence. Then make them work together.
I / THE SHELL
Cast the skin.
Keep the space.
Hollow metal panels, removable mounts, and overlapping joint armor. No solid metal costume chunks.
Explore the armor ↗II / THE SUPPORT
Carry the armor.
Follow the human.
A separate ground-load frame and passive assistance are the goal. A verified load path is still to be designed.
Explore the mechanism ↗III / THE SYSTEMS
Room for the wiring.
And what comes next.
Serviceable channels, modular electronics, cooling, and sensors—with physical controls that outlive a dead battery.

03 / A LITTLE LESS SCIENCE FICTION
THE HUD
CAN WAIT.
THE HUMAN
CAN’T.
A future used HoloLens 2—or another suitable display—could turn the helmet into a glanceable interface for suit status, communications, and maintenance.
First: visibility, breathing room, a manual faceplate, and a removable carrier. No promise to shrink calibrated optics.
Inside the helmet plan04 / BUILDING IN PUBLIC
Big ambition. Honest progress.
The model is real. So are the things it has not solved yet.
Motion before metal.
Opening-path collisions, shoulder travel, deep elbow flexion, and the continuous load path remain unresolved.
See the actual blockers ↗Cast. Assemble. Instrument.
Foundry trials, real hardware, off-body load tests, and eventually an AR module. No invented completion percentage.

UNDER THE HOOD.
R47 / print prep
Closed source-linked candidates and Z0 print orientations are now packaged.
R47 repairs the open neck source export, orients the registered source parts for slicer review, and adds a source-family resolver for the remaining DaDave files.
R48 added
Source resolver + shell plan
New exact DaDave source-region registrations, source-family retain/replace/discard decisions, and a 135-row shell-candidate planning table.
