Version & configuration
Requirements, CAD, models, software, parameters, BOM and as-built configurations use stable identifiers with change impact.
Engineering & manufacturing · Product development path
From a real problem to a reviewable, reproducible and accountable robot prototype.
This is not a catalogue of drawings to copy blindly. It is an engineering evidence chain connecting requirements, digital models, simulation, prototype manufacturing and safe release. Every stage states its inputs, deliverables, review questions and stop conditions.
Core principle
Drawings are one part of an engineering package; evidence makes the package reviewable.
Buildable is not the same as safe to operate; demonstrable is not the same as repeatably deliverable. FUURAA connects every phase to inspectable artefacts and sources so readers can see what is known, what remains uncertain and what work comes next.
Five review gates
Every stage is an actionable work desk.
Read sequentially or enter at the project’s current stage. A later phase cannot repair a foundational assumption that was never made visible earlier.
01Gate 01
Requirements, operating boundaries & evidence plan
Turn a promising robot idea into a measurable job, a bounded operating environment and a reviewable evidence plan before selecting hardware.
Open stage →02Gate 02Reference architecture, digital model & interface contract
Translate requirements into a versioned system architecture that connects mechanics, electronics, compute, software, data and human control.
Open stage →03Gate 03Simulation, integration & verification evidence
Use simulation as a controlled evidence instrument: expose assumptions, inject failures, compare against reality and preserve reproducible results.
Open stage →04Gate 04Prototype, reproducible build & manufacturing readiness
Turn controlled models into a reproducible physical prototype with a traceable bill of materials, assembly process, calibration and quality evidence.
Open stage →05Gate 05Safety case, controlled release & field learning
Assemble a claim–argument–evidence case, release only within approved boundaries and keep evidence current as hardware, software and operations change.
Open stage →Evidence spine across the lifecycle
As a project advances, its records must increasingly explain why it may continue.
Provenance & licences
Every external design, codebase, dataset, mesh and model records owner, version, terms, modifications and distribution decision.
Requirements-to-test trace
Every consequential requirement connects to analysis, inspection, demonstration or test evidence; open items stay visible.
Risk & accountability
Hazards, assumptions, residual risk, reviewers, approved scope and stop conditions remain current.
Operations & feedback
Field interventions, near misses, failures, repairs, model drift and environment change flow back into engineering evidence.
Boundary of public knowledge
Help readers advance compliant engineering without hiding risk behind the word ‘open’.
This path can provide
