Stage1b Audit: Gap Closure
Audit updated April 26, 2026| Gap found | Decision impact | Stage1b update | Status |
|---|---|---|---|
| Route-grade risk was mentioned in prose but not modeled as an explicit input/output variable in the tool. | Users could miss slope-driven instability and over-trust fit output for inclined routes. | Added route grade (%) field, grade amplification factor, and explicit >10% boundary warning aligned to 1910.178(n) travel clauses. | Closed |
| Cross-vendor load claims mixed kg/set and lb/wheel units without one normalized basis. | Procurement comparisons could be distorted by unit mismatch and wrong per-wheel/per-set interpretation. | Added NIST-based unit normalization path and explicit converted examples for AndyMark/Nexus references. | Closed |
| US safety-standard boundary for driverless AGV deployments was under-specified. | Teams could misclassify pre-screen results as sufficient without mapping to applicable system-level standard track. | Added ANSI/ITSDF B56.5-2024 scope/effective-date anchor and linked it to checker-to-compliance handoff guidance. | Closed |
| Impact and durability boundaries lacked public failure examples. | Cost risk could be understated when routes include repeated seam impacts and shock loads. | Added AndyMark durability white-paper datapoints (70lb performance degradation and 12-inch concrete-drop spindle failure). | Closed |
| Kinematic assumptions were not explicitly tied to a peer-reviewed framework. | Cross-functional reviewers could not quickly verify why the checker includes directionality and lateral-load factors. | Added CMU 1987 kinematic-modeling source to clarify model lineage and non-durability scope. | Closed |
| No open public standard publishes the exact 85/110 benchmark bands and 3.6/5.2 stress-index cutoffs. | Potential overconfidence if heuristics are interpreted as compliance or universal engineering limits. | Kept explicit pending-confirmation status and require supplier fatigue test plus pilot wear trend before final release. | Pending confirmation |
Report Summary: Key Conclusions
Updated April 26, 202686%-110% benchmark usage or stress index 3.7-5.2 or stability 55-69
Compared against 100kg/set reference for first-pass screening
Higher index means increased roller stress and wear risk
Rubber roller on Mixed concrete with joints
- Indoor AGV routes with floor joints around or below 2 mm.
- Projects that need quick pre-screening before detailed supplier validation.
- Teams comparing 100mm roller material options under similar duty assumptions.
- Outdoor or contamination-heavy lanes without reliable floor and wear data.
- Scenarios requiring final compliance evidence without system-level safety work.
- High-shock missions where benchmark usage consistently exceeds 110%.
- Sustained routes above 10% grade without dedicated pilot and engineering review.
Methodology and Evidence
1) Dynamic load/wheel = static load x safety factor x speed factor x joint factor x grade factor x floor factor.
2) Benchmark usage % = dynamic load/set / 100kg primary benchmark, with a secondary 45kg lower-reference check.
3) Stress index = load/roller x diameter ratio x material multiplier.
4) Stability score penalizes floor roughness, joints, speed, route grade, and long daily distance.
| Assumption | Value | Reason |
|---|---|---|
| Benchmark set load | 45-100 kg/set (public 100mm examples) | Nexus 100mm references show large within-class spread; this tool uses 100kg/set as primary benchmark and 45kg as lower-reference guardrail |
| Light-duty counterexample | 15 kg class (97mm) | DFRobot 97mm reference prevents treating "mecanum wheel" as one universal industrial class |
| Speed factor coefficient | 0.08 per m/s | Conservative amplification for lateral motion in first-pass sizing |
| Joint factor coefficient | 0.02 per mm | Approximates repeated seam impact sensitivity |
| Grade factor coefficient | 0.015 per % grade | Makes slope impact explicit and aligns warning logic to 1910.178(n) grade-travel boundary (above 10%). |
| Cross-vendor unit normalization | 1 lb = 0.4535924 kg | Uses NIST SI factor so lb/wheel and kg/set claims can be compared on one basis. |
| Stress-index thresholds | 3.6 / 5.2 | Engineering heuristics; no matching open standard cutoffs found, so final release requires supplier and pilot evidence |
| Regulatory operation boundary | Grade/surface constraints per OSHA 1910.178 | Regulation informs route-risk inputs but does not replace wheel durability validation |

| Decision question | New data point | Boundary / counterexample | Action | Sources |
|---|---|---|---|---|
| Can two 100mm mecanum wheels have the same capacity by default? | Nexus publishes two 100mm references with very different claims: 45kg/set (14094) and 100kg/set (NM100A heavy duty). | Same diameter does not normalize hub design, roller architecture, or duty-cycle assumptions. | Treat diameter as a search filter only; compare using published set/wheel load plus duty definition. | Nexus NM100A page + Nexus 14094 page (checked 2026-04-26) |
| Can lb/wheel and kg/set claims be compared directly without conversion? | AndyMark publishes 80/80/440 lb per wheel (6/8/10 in), which is 36.3/36.3/199.6 kg per wheel using NIST factor 1 lb = 0.4535924 kg. | Per-wheel and per-set claims are not interchangeable; multiply by wheel count and keep unit basis explicit. | Normalize every supplier claim to one basis (kg/wheel and kg/set) before ranking options or setting safety margin. | AndyMark MecanumWheelSpecSheet + NIST SI Appendix B.9 (checked 2026-04-26) |
| Is a smaller-diameter mecanum wheel automatically unusable? | DFRobot 97mm unit publishes 45° roller angle with a 15kg load class and silicone-rubber rollers, showing it can work for light-duty tasks. | This is a light-duty example and does not support direct transfer to industrial AGV payload envelopes. | Use smaller diameter only for prototype/light payload scenarios unless industrial load evidence is provided. | DFRobot 97mm page (checked 2026-04-26) |
| Should route grade be a mandatory screening input? | eCFR 1910.178(n)(7) requires slow grade travel and specifies >10% grade handling posture for loaded trucks; 1910.178(n)(10) adds wet/slippery-floor slowdown. | These clauses are operation constraints, not wheel-fatigue acceptance thresholds. | Collect route grade in first-pass sizing and trigger mandatory pilot/engineering review when grade exceeds 10%. | eCFR 29 CFR 1910 Subpart N (checked 2026-04-26) |
| Is checker output enough to satisfy US AGV safety governance? | ITSDF lists ANSI/ITSDF B56.5-2024 for driverless automatic guided industrial vehicles with effective date 2025-12-16. | Standard title/scope confirms system-level requirements; checker output alone is not a conformity certificate. | Map checker result to formal standard track (ISO 3691-4 and/or B56.5) before release decisions. | ITSDF B56 standards page (checked 2026-04-26) |
| Can training documentation ignore route slope and floor conditions? | OSHA final rule for 1910.178(l) lists workplace training topics including surface conditions and ramps/sloped surfaces. | Training obligations do not set numeric wheel-rating limits by themselves. | Treat unknown slope/surface data as low-confidence input and block direct PO without field measurement. | OSHA PIT Operator Training Final Rule (checked 2026-04-26) |
| Can one heavy-duty claim replace duty validation? | AndyMark published load references span 80 to 440 lb per wheel across wheel sizes, showing architecture-specific rating spread. | Material hardness and one vendor architecture do not capture floor shock spectrum, route profile, or maintenance interval. | Require both product-level load/hardness data and route-level pilot evidence before release. | AndyMark product references + Mecanum spec sheet (checked 2026-04-26) |
| What is a public shock-risk signal for mecanum rollers under abuse? | AndyMark white paper reports reduced strafing at 70lb in FTC tests and roller-spindle breakage after a 12-inch concrete drop. | Test context is FTC-scale and single-vendor; use as caution evidence, not a universal lifecycle model. | If your route includes recurrent impacts, force a pilot gate before purchase commitment. | AndyMark durability white paper (checked 2026-04-26) |
| Can floor-joint and slope data be skipped during first-pass selection? | OSHA 1910.178 specifies grade-handling constraints (including >10% grade loading orientation) and cautions on wet/slippery travel speed. | These are operation-safety constraints and do not replace component fatigue or thermal validation. | Keep floor-joint and slope as mandatory inputs; unknown values should reduce confidence and trigger pilot. | eCFR 1910.178 + OSHA PIT physical conditions eTool (checked 2026-04-26) |
| Does this checker replace system-level AGV compliance work? | ISO 3691-4:2023 scope targets driverless industrial truck systems, not a wheel-only pass/fail certificate. | Public abstract is available, but full clauses are paywalled and still must be handled in formal compliance workflow. | Use checker output as component pre-screen input to ISO/plant safety processes, not as final conformity evidence. | ISO 3691-4 page (checked 2026-04-26) |
| Are the fit thresholds in this page an official standard requirement? | No open public source was found with identical 85%/110% benchmark bands or stress-index cutoffs. | These thresholds are engineering heuristics for pre-screening only. | Status pending confirmation: keep supplier fatigue report and pilot trend as release gate. | Source audit updated 2026-04-26; detailed clauses on many standards are paywalled |

| 100mm polyurethane roller mecanum | AndyMark family reference: 80-440 lb/wheel (36.3-199.6 kg/wheel) depending on wheel size | Medium-High | Higher wear resistance need with reduced grip tolerance | Public baseline exists but not same-size apples-to-apples with 100mm references |
| 97mm hobby/light-duty mecanum | 15 kg class public example | High | Prototype education or very light payload robots | Public product-page evidence available |
| Custom reinforced mecanum module | No open universal benchmark | Low-Medium after validation | High-shock or beyond-boundary production use | Requires supplier report + pilot data |
| Band | Boundary | Operational fit | Action |
|---|---|---|---|
| Fit for 100mm rubber roller pre-screen | <= 85% benchmark usage and stress index <= 3.6 with stability >= 70 | Indoor AGV lanes with low floor joints and controlled lateral speed. | Proceed to RFQ with this output and request supplier drawing confirmation. |
| Borderline, verification required | 86%-110% benchmark usage or stress index 3.7-5.2 or stability 55-69 | Mixed-floor routes where roller wear and vibration trend must be verified in pilot. | Run short pilot test and request roller hardness + fatigue report before PO. |
| Not fit, move to stronger module | > 110% benchmark usage or stress index > 5.2 or stability < 55 | High shock, high cycle, or heavy payload profile beyond 100mm rubber pre-screen envelope. | Switch to reinforced/custom wheel module and perform vehicle-level validation. |
Fit thresholds are pre-screening heuristics and must be replaced by supplier fatigue evidence for final release. Load comparisons above normalize lb-to-kg using NIST SI factors. Cross-source load references were checked through 2026-04-26.
| Risk | Trigger | Mitigation |
|---|---|---|
| Misuse risk | Treating checker output as final compliance proof | Run full vehicle-level validation and applicable safety workflow |
| Benchmark overconfidence risk | Using one product benchmark as universal limit | Compare multiple supplier datasheets and pilot data before PO |
| Unit mismatch risk | Mixing kg/set and lb/wheel claims without conversion | Normalize every claim to kg/wheel and kg/set before commercial comparison |
| Slope underestimation risk | Route grade above 10% treated as normal operation | Trigger pilot + engineering review gate whenever route grade exceeds 10% |
| Cost/wear risk | Ignoring daily distance and maintenance intervals | Add wear inspection gates and maintain spare-roller stock plan |
| Scenario mismatch risk | Using smooth-floor assumptions on rough routes | Default to rough-floor assumptions until measured route data is available |
| Alias dilution risk | Creating multiple near-duplicate URLs for same intent | Keep single canonical URL and route all alias intent here |
