A serviceable suit needs planned routes for power, data, moving cables, airflow, and maintenance. These are draft reservations—not a released harness, circuit board, or wearable control system.
Select a region to inspect the proposed routing, service access, and keep-out requirements.
A removable distribution and controller tray behind the torso shell. Keep access, cooling, and padding separate.
Bolt-on or strap-mounted carriers are the starting proposal. Do not machine a convenient groove through an unreviewed load-bearing frame.
Nominal coupon dimensions only. Cable fill, flex radius, insulation, heat, fasteners, and suitability for the suit are not validated.
Put service carriers outboard of the padded contact areas. Round entries, add suitable insulating edge protection, and retain access to every connector.
Support both sides of each flexible crossing. Route away from pinch folds and the spring sweep. Cable-specific dynamic bend radius and cycle tests govern loop design.
Use keyed, labeled module connectors with service slack. A connector must not carry panel weight or bridge an emergency opening.
The D01 download includes a channel base, matching lid, and an accessory backplate in STEP/STL, with editable CadQuery source. Unloaded fit coupons only.
A candidate low-voltage accessory architecture. Voltages, fuse ratings, conductors, connectors, battery choice, and runtime remain unselected.
Separate protected branch. Intended to remain available when only the motion branch is isolated.
Regulated logic rails, local diagnostics, and independent physical indicators.
Separately switched driver supply. Physical stop, default-disabled output, and deliberate restart.
The total disconnect removes all electrical power—including fans. A motion stop isolates only accessory actuation. Neither operation unloads gas springs or guarantees a panel will move freely.
No metal-frame current return is proposed. Use dedicated insulated supply and return conductors. Source and branch protection must be designed for the actual pack, wire, connector, and load.
Start with an appropriate commercial protected pack and manufacturer-approved charging arrangement. Keep it removable and accessible, with a reviewed retention, insulation, venting, and thermal plan. Initial testing uses inert battery mass or a current-limited bench supply, off-body.
A future headset keeps its manufacturer-supported power system. There is no proposed splice into a HoloLens battery or optical assembly.
A processor watchdog or driver fault pin is not a certified safety system. No cloud service or website button is allowed to control wearer retention or load-bearing joints.
All sensors below are proposed. The website’s animations and readings are not connected to hardware.
| Candidate | Proposed position & purpose | Limit / next test |
|---|---|---|
| Temperature & humidity | Helmet intake/exhaust and torso air path; electronics and battery temperature channels. | Ambient readings are not core-body temperature or medical clearance. Establish sensor placement and stop criteria separately. |
| Fan tachometer | Verify commanded fans are actually turning; compare intake and exhaust behavior. | RPM alone does not prove airflow. Test obstructed vents and fan failure off-body. |
| Latch & travel switches | Door-position indication and independent accessory travel limits. | A switch state does not prove latch engagement strength, pinch clearance, or safe retention. |
| Voltage / current | Accessory branch diagnostics and energy accounting. | Not a replacement for fuses or pack protection; startup and fault behavior need measurement. |
| Inertial sensors | Log orientation/motion during controlled testing; optionally generate a local advisory. | Not a fall-arrest system. Never command joints to lock because a fall is inferred. |
| Short-range ToF | Experimental rear/side obstacle advisory through dedicated optical windows. | No guaranteed obstacle detection. Validate lighting, surfaces, covers, blind spots, and clothing obstruction. |
| Pressure mapping | Temporary fit-test pads at intended contact areas. | Calibration and placement matter. A quiet graph does not establish comfort or tissue safety. |
| Optional camera / microphone | Comms or deliberate recording with a visible indicator and physical privacy control. | Not face recognition or covert surveillance. No always-recording default; no dependency for direct vision. |

Guarded intake/exhaust, adjustable airflow, local override, tach feedback, and a cleanable path. Test with the helmet open and off the wearer first.
A low-energy, counterbalanced mechanism with retained parts, travel limits, local hold-to-run input, physical guarding, and a disengagement path.
No selected motor, force, gear ratio, or linkage. The faceplate remains manually openable with the drive disengaged.
No walking motors, powered punches, automated joint locks, powered retention latches, or autonomous body movement in this architecture.
Passive assistance is itself unresolved and needs a separate mechanical test program.
Attachment coordinates, retained-fastener choices, pull-out loads, emergency breakaway behavior, and mass limits remain to be engineered. Neither cosmetic shells nor cable carriers become structural anchor points by default.
Explore an illustrative runtime calculation. Replace every example with measured loads before selecting hardware; no actual pack, conductor or protection is sized by this tool.
Usable fraction lumps reserve/loss assumptions together. It is not a measured efficiency or safe discharge limit.
50 Wh × 0.80 ÷ 20 W = 2.00 hours
Steady average-load estimate only. Not measured endurance; excludes transient behavior and any powered body joints.
Logic tray, removable lid, cable keeper, edge transition, pad carrier and ventilation interface—all available to inspect and download.
