AETEC / ASM
Technical basis, Rev E

Customer discussion: 16 October 2026. Three alternatives are shown independently. This revision develops the mechanical representation, proposed storage around the I/O port and operator workflow. Existing quotations and commercial scope remain unchanged.

Design development, not released for manufacture. The drawings and STEP assemblies show geometry and connections for review. Structural calculations, verified loads, vendor interfaces, tolerances, safeguards and the L3 installation survey are still required. Detailed geometry does not establish load capacity or certification.

Concepts and proposed capacity

Concept	Base rack L x W x H, mm	Tray, mm	Base working	Opposite	Overhead	Proposed total
A Toolroom	10000 x 3200 x 5000	1200 x 800	160	16	9	185
B Door panels	9000 x 4600 x 5000	2600 x 1100	64	12	7	83
C Metro trolley	7600 x 3400 x 5000	1200 x 800	100	10	5	115

B retains 8 reserved positions in its original 72-position rack. New storage uses a separate end bay. Access extensions, guards, maintenance areas and cart circulation are additional to the base rack footprint. A catch canopy sits below overhead storage; its structural rating remains unissued. A sliding guard avoids lifting into the added shelves.

Load and height basis

Concept	Loaded tray basis	Transfer basis	Top stored load	Highest load during lift
A	100 kg tooling + 25 kg tray	150 kg	4530 mm	4540 mm
B	50 kg panel + 35 kg tray	100 kg	4530 mm	4570 mm
C	25 kg per loaded tray (assumption)	Vendor sizing required	4200 mm	4240 mm

Structure height is 5000 mm. The nominal room height of 5500 mm is an assumption, not a surveyed beam soffit. Allow for services, fire protection, maintenance and the actual crane supplier envelope. Tooling envelope is 1100 x 700 x 180 mm; panel envelope is 2500 x 1000 x 240 mm provisionally. Customer approval of horizontal panel storage is outstanding.

Full inventory mass before rack and crane: A 23,125 kg, B 7,055 kg, C 2,875 kg at the stated load assumptions. These are structural load inputs, not slab approval. Check point reactions, anchor forces and dynamic cases.

L3 source drawing and pillars

Source: customer-provided L3 Layout.dwg, AC1032. Converted DXF is supplied alongside the unchanged DWG.
Customer-reported grid pitch is 9000 x 9000 mm. Approximately 800 mm wall projections do not confirm the structural column dimensions.
Default assumed pillar section is 800 x 800 mm. Between faces: 8200 x 8200 mm. With a 50 mm margin on each face, between keep-outs: 8100 x 8100 mm, before service space.
The approximately 20.45 x 11.60 m cloud is a markup envelope, not the net usable room area. No building pillar is removed.
Millimetre interpretation follows the stated 9 m grid and 1200 mm panel blocks. DWG insertion units report inches; confirm against surveyed dimensions.
Architectural outlines are extruded to assumed heights. Structural beam sizes, underside levels, slab reinforcement, egress and final AMR swept routes remain unresolved.

Mechanical detail represented

Rack columns: RHS 80 x 80 x 4 study section. Beams: RHS 80 x 40 x 3. Rear beams span between columns. Short front supports stop outside the payload aperture.
Rail guides: nominal 55 x 50 x 4 angle. A/C rack rail centres +/-585 mm; B +/-1285 mm from tray centre. A/B maximum payload has only 7.5 mm nominal lateral clearance to the flange edge. Include lateral positioning error and deflection.
Columns use separate 220 x 220 x 24 study foot plates with four M16 anchor locations on 150 x 150 centres. Anchor selection, embedment, slab checks, welds, bolt grades, lengths and torque remain unissued.
Rear cross braces, connection plates, washers, bolts, guide rails, carriage blocks, drive housings, sheaves, travel rollers and cable carrier links are modelled.
Fence panels show wire, posts, feet, clamps, guard lock and a sliding entry panel. Guard distances, stopping time, guard-lock function and safety architecture need validation.
Fasteners and slotted profiles are simplified geometric representations; use the selected supplier CAD and fastening instructions for production drawings.

Concept C trolley and tray pool

Active trolley: 45 mm slotted aluminum frame with stainless guide angles, outboard mounting brackets, four 190 mm caster wheels, brake pedals, rear stops and push handle.
Model envelope including caster plates and handle: approximately 1420 x 1171 x 1666 mm. Frame width alone is 1345 mm. Use the full envelope for circulation checks.
Four support datums: 500 / 800 / 1100 / 1400 mm. Level 02 is the illustrated free destination; the other three levels show example parts.
A 200 mm loaded tray and 40 mm insertion lift reach 1040 mm at level 02. The next rail underside is 1050 mm. The nominal gap is 10 mm before tolerances and deflection.
In the example: 95 stored trays and 20 free positions in the revised 115-position rack. Pool 150 = 95 stored + 40 on carts + 15 other controlled. Pool 200 = 95 + 80 + 25.
Cart QR identifies CART-007. MiR Hook uses a separately configured AprilTag. Identity does not provide mechanical docking accuracy.
Cart tare, maximum payload, centre of gravity, caster ratings, bonding continuity and cleaning requirements need confirmation.

MiR transport alternatives

MiR250 manufacturer nominal body: 800 x 580 x 300 mm, 250 kg platform payload. The public body mesh comes from DFKI-NI mir_robot; added wheel and sensor details are representative external geometry.
Custom under-cart option: nominal 30 mm plate stroke from centre height 314 to 344 mm. Plate top contacts a receiver face at 351.5 mm. Wheels stay on the floor. Receiver pockets and positive latch are a preliminary interface study.
The 250 kg platform rating is not a tow rating for the custom coupling. Verify tow forces, traction, gradients, cart brakes, turning and loss-of-coupling behavior.
MiR250 Hook: manufacturer publishes up to 500 kg application load and AprilTag recognition. This animated Hook interface is an external geometry study, not certified OEM CAD. Obtain the exact cart interface and route requirements from MiR.
MiR Shelf Carrier 250: current application page publishes up to 300 kg. Its approved pickup geometry differs from the proposed wheel-supported custom coupling.
MiR600 is a heavier-load alternative with a published 600 kg payload. Selection should follow actual loads and route, not headline capacity alone.

10K cleanroom requirement

Use Class 10,000 / 10K / ISO Class 7. Do not label the requirement “ISO 10000”. The current MiR250 specification lists an optional ISO Class 4 configuration. Confirm that exact option and its test scope. It does not qualify the custom trolley, top module, rack, lubricants, handling process or installed system. Review particle generation, cleanable surfaces, airflow, sealed bearings and bonding. Anodized aluminum alone does not establish ESD continuity.

Interactive simulation and HMI

The app starts a visible demonstration when supported, except when the browser requests reduced motion. Play, pause, next step, reset, speed, top/side/interface views and manual camera orbit are available. A/B/C dimensions remain editable independently. Invalid tray, pitch or machine dimensions block the demo. Layout warnings do not constitute a site clearance approval.

HMI is local demonstration data. Select a job, verify IDs, reserve, Start, monitor and commit handover. Completion stays disabled until simulated transfer completion. An interlock loss holds motion and retains the reservation. Acknowledge alone never restarts. A repeated completion does not update inventory again. Active jobs lock dimensional and concept changes. Actual WMS, SAP, PLC and MiR connections require a separately implemented integration.

ERP/SAP owns business demand; WMS owns inventory/reservations; WCS coordinates crane, dock and fleet; the safety PLC independently owns motion permission. Messages need job ID, transaction ID, tray/cart/level IDs, source, destination, timestamps and state. Reconcile an uncertain physical transfer before retrying an inventory change.

Verification boundary

Every proposed working position is sampled for pickup and withdrawal. Checks include the tray deck, maximum payload, forks and core carriage/mast envelopes against rack posts, loaded neighbours and detailed structural boxes. The complete illustrated transfer, camera-origin clearance and straight cart movements are sampled. Additional detailed trolley checks cover caster/profile/receiver envelopes and guards. These are sampled geometric checks, not continuous collision proof or safety certification. Flexible cables, full OEM linkage sweeps, stopping distances, turning paths, tolerances and structural deflection require final CAD and commissioning evidence.

Website source builds and HMI state transitions are checked. This environment does not provide the required browser QA surface, so browser-level interaction and frame-rate verification remain unperformed. Videos use synthetic English female narration generated locally. Video decoding and audio levels are checked; human listening QA is not available here.

Manufacturer and architecture references

References checked 15 October 2026. Manufacturer limits are configuration dependent. Customer-specific dimensions remain assumptions unless explicitly identified as source drawing geometry or customer-stated pitch.
