Robotics Architecture

137. Robotic System Development Lifecycle

Every System05 robotic system shall follow a controlled development lifecycle from initial need definition through retirement.

The lifecycle shall include:

Requirements shall define not only intended behavior but also prohibited actions, failure responses, evidence obligations, human roles, Operational Design Domain, and safe recovery states.

Development shall maintain traceability among requirements, hazards, design decisions, software, hardware, tests, results, deviations, and approvals.

Robotic capability shall be introduced progressively. A function demonstrated in simulation shall not automatically be authorized in a laboratory; laboratory success shall not automatically authorize field deployment; and field success in one environment shall not establish universal capability.

Changes to robots, tools, payloads, controllers, AI models, maps, Interfaces, work packages, safety parameters, or operating environments shall be evaluated to determine whether earlier evidence remains valid.

Unresolved high-consequence defects, incomplete safety requirements, unknown failure behavior, or insufficient verification evidence shall prevent release.

The lifecycle shall remain compatible with iterative development, but iteration shall not bypass engineering control, configuration management, independent review, or safety authorization.

138. Simulation, Digital Twin Testing and Virtual Commissioning

Simulation, Digital Twin testing, and Virtual Commissioning shall be used to identify problems before physical deployment and to reduce the cost and risk of robotic experimentation.

Simulation may evaluate:

The simulation model shall identify its assumptions, fidelity, uncertainty, excluded phenomena, valid parameter ranges, and relationship to the intended physical configuration.

A development simulation, commissioning model, operational Digital Twin, and authoritative Building BIOS record shall not be treated as interchangeable. Each shall have a defined role and level of trust.

Virtual Commissioning shall test command sequences, PLC logic, state transitions, interlocks, work packages, alarms, fault responses, and human interfaces before connection to operational equipment.

Simulation shall include normal conditions, boundary conditions, foreseeable misuse, component variation, sensor uncertainty, timing variation, communication delay, and representative failure combinations.

A successful simulation shall demonstrate consistency with the model; it shall not prove that the physical system will behave identically. Safety-critical conclusions shall be confirmed through appropriate physical testing.

Differences between simulated and observed physical behavior shall be recorded and used to improve models, uncertainty limits, and future tests.

139. Hardware-in-the-Loop, Laboratory and Prototype Testing

System05 shall use Hardware-in-the-Loop, laboratory, and prototype testing to evaluate interactions that cannot be trusted through software simulation alone.

Hardware-in-the-Loop testing may connect real controllers, sensors, tools, drives, safety devices, PLCs, or communication equipment to simulated robots, structures, environments, and faults.

Laboratory testing shall provide controlled evaluation of:

Prototype testing shall use representative materials, tolerances, surface conditions, component masses, payload centers of gravity, fasteners, contamination, and assembly variations.

Test equipment, instruments, fixtures, reference standards, and measurement uncertainty shall be documented and calibrated where required.

Safety-related testing shall not create uncontrolled hazards. Physical limits, containment, exclusion zones, emergency controls, and test-abort criteria shall be established before execution.

Failures shall be preserved as engineering evidence. A failed test shall not be removed from the record merely because a later design revision passes.

A prototype shall be clearly identified as experimental and shall not enter ordinary construction service unless the applicable release, inspection, and certification requirements have been satisfied.

140. Pilot and Field Testing

Pilot and field testing shall validate robotic behavior under representative operational conditions while maintaining bounded scope and controlled consequence.

A field pilot shall define:

Initial pilots should favor controlled, repeatable, reversible, and observable tasks. High-consequence structural release, utility energization, unrestricted occupied-building operation, and unsupervised autonomy should not be used as initial demonstrations.

Field testing shall account for real-world variation, including lighting, dust, weather, surface conditions, worker behavior, component variation, communication instability, layout deviations, and unexpected obstacles.

Pilot personnel shall understand that a prototype may behave differently from a released product. Production pressure shall not override pilot limitations.

Every abnormal event, manual intervention, near miss, unexpected resistance, state conflict, aborted task, and deviation from the work package shall be recorded.

Completion of a pilot shall not automatically authorize wider deployment. Expansion to new tasks, sites, payloads, tools, or autonomy levels shall require review of the accumulated evidence and remaining uncertainty.

141. Reference Scenarios and Test Cases

System05 shall maintain governed Reference Scenarios and Test Cases for evaluating robotic compatibility, performance, safety, and interoperability.

Reference scenarios may cover:

Each test case shall define initial state, required configuration, inputs, environmental conditions, permitted actions, expected outputs, pass criteria, prohibited outcomes, evidence requirements, and cleanup state.

Test sets shall include positive cases, negative cases, boundary cases, malformed inputs, conflicting identities, invalid state transitions, stale commands, failed sensors, and foreseeable misuse.

Reference scenarios shall be version-controlled. Results obtained under one version shall remain traceable and shall not automatically satisfy materially changed requirements.

Manufacturers may use private tests in addition to System05 reference tests, but private testing shall not replace required common conformance cases.

A system trained directly against published tests shall also be evaluated against controlled, previously unseen scenarios to reduce test-specific optimization and concealed brittleness.

Metrics may include:

Accuracy and repeatability shall remain distinct. A robot may repeatedly reach the wrong position, or reach the correct average position with unacceptable variation.

Performance testing shall represent relevant payloads, reach positions, speeds, tools, component tolerances, surface conditions, environmental conditions, and equipment wear.

Nominal manufacturer specifications shall not substitute for validation of the integrated robot–tool–component–Interface configuration.

Precision requirements shall derive from the engineering function. The robot shall not be required to achieve unnecessarily restrictive precision when the Interface can safely accommodate variation through lead-in geometry, compliance, capture, or self-alignment.

Where performance approaches an acceptance boundary, measurement uncertainty shall be included in the decision.

Performance deterioration shall be detectable through calibration checks, process monitoring, inspection results, and maintenance records. Continued operation shall not be justified solely by historical success.

143. Reliability and Availability

Robotic reliability and availability shall be engineered according to task consequence, operational environment, maintenance capability, and required continuity.

Assessment may include:

Reliability testing shall include representative duty cycles, repeated loading, environmental exposure, tool changes, calibration drift, contamination, battery degradation, cable or hose wear, and software restart.

A highly available system shall not be assumed safe. Availability measures continuity of service; safety governs whether continued service is acceptable.

System architecture should prevent individual noncritical failures from unnecessarily stopping an entire site while ensuring that consequential failures produce an appropriately conservative response.

Maintenance and replacement strategies shall consider modular robots, replaceable tools, swappable controllers, recoverable software, local spare parts, and regional service capability.

Reliability claims shall specify the configuration, environment, task, observation period, and statistical confidence to which they apply.

Recurring failures, even when individually recoverable, shall trigger engineering review when they indicate a systematic weakness or normalization of degraded operation.

Testing shall evaluate:

Degraded-mode tests shall include sensor loss, reduced localization, unavailable cloud services, partial communication failure, tool malfunction, low battery, controller restart, missing evidence, blocked access, and conflicting system state.

Recovery testing shall not focus only on restoring motion. It shall verify payload condition, temporary structural stability, work-zone status, tool state, component identity, calibration, authority, and the integrity of any work completed before the fault.

The system shall distinguish automatic recovery, supervised recovery, maintenance intervention, and emergency response.

Repeated automatic retries shall be bounded. A system shall not repeatedly apply force, reissue commands, cycle mechanisms, or restart software when the underlying physical condition remains unknown.

A degraded mode that cannot be tested safely or characterized adequately shall not be relied upon for operational authorization.

145. Robotic Safety Verification and Validation

Robotic Safety Verification and Validation shall demonstrate both that the system was built according to its safety requirements and that those requirements are adequate for the intended operation.

Verification shall ask whether the implemented system conforms to its specified architecture, limits, state machines, protective functions, and failure responses.

Validation shall ask whether the complete system is acceptably safe for its intended task, users, site conditions, payloads, tools, and Operational Design Domain.

The process shall include:

Safety verification shall cover the integrated robot, mobile platform, controller, safety system, tool, payload, component, work zone, temporary structure, and relevant digital services.

Independent review shall be required where consequence, uncertainty, novelty, or regulatory obligation warrants it.

A safety function shall not pass merely because an alarm occurred. The required physical response, response time, stopping behavior, retained protection, and recovery state shall be demonstrated.

Safety validation evidence shall remain linked to the tested configuration. Material changes shall trigger impact assessment and, where necessary, revalidation.

146. Adversarial and Cybersecurity Testing

Robotic systems shall undergo adversarial and cybersecurity testing proportional to their physical authority and potential consequence.

Testing may include:

Testing shall evaluate whether cyber compromise can produce unsafe motion, incorrect physical work, hidden state change, falsified evidence, or unauthorized modification of the Building BIOS.

Adversarial testing shall occur in controlled environments with defined authorization, containment, restoration, and emergency procedures. Testing of operational robots shall not create unacceptable risk to people, structures, utilities, or property.

Red-team and penetration testing should include paths across IT networks, edge systems, controllers, tools, maintenance interfaces, supplier packages, and human approval processes.

AI-enabled perception and planning systems shall be tested against ambiguity, misleading input, unfamiliar configurations, data poisoning, and attempts to induce actions outside approved scope.

Discovered vulnerabilities shall be classified, corrected, retested, communicated to affected parties, and incorporated into update or recall decisions.

147. Human-Factors and Usability Testing

Human-Factors and Usability Testing shall verify that people can understand, supervise, interrupt, recover, and safely interact with robotic systems.

Testing shall include representative:

Evaluation shall address mode awareness, alert comprehension, workload, fatigue, attention, trust, control placement, emergency-stop access, approval interfaces, handover, recovery instructions, and interpretation of uncertainty.

The system shall be tested for mode confusion, alert flooding, misleading success indicators, excessive confirmation requests, hidden degraded states, automation bias, and delayed human response.

Interfaces shall not require users to infer safety-critical meaning from undocumented colors, codes, gestures, sounds, or specialist terminology.

Training effectiveness shall be tested rather than assumed. Successful completion of a training module shall not alone demonstrate competence for high-consequence operation.

Where occupants or untrained persons may encounter robots, warnings, boundaries, and expected behavior shall be understandable without construction or robotics expertise.

Usability improvements shall not remove necessary engineering information or make consequential actions appear simpler or more certain than they are.

148. Robot Conformance and Certification Levels

System05 shall establish graduated Robot Conformance and Certification Levels so that capability claims remain specific, comparable, and evidence-based.

The framework may include:

RCL-0 — Unassessed or Experimental: No System05 conformance claim.

RCL-1 — Digital and Protocol Conformance: Identity, schemas, messages, state machines, cybersecurity basics, and API behavior verified.

RCL-2 — Physical Interface and Laboratory Conformance: Physical Interfaces, tools, measurement behavior, safety functions, and controlled laboratory tasks verified.

RCL-3 — Task and ODD Qualification: Defined robotic tasks validated within a declared Operational Design Domain.

RCL-4 — Integrated Deployment Conformance: Robot, tool, work package, site profile, building configuration, and operational controls evaluated as an integrated deployment.

RCL-5 — Bounded Advanced Autonomy: Higher autonomous capability validated for specifically declared tasks, conditions, authority boundaries, and supervision requirements.

The detailed level structure may evolve through governed standards, but no level shall imply unlimited capability.

Certification shall identify the exact robot, hardware, firmware, software, tool, payload range, task classes, Interface versions, safety profile, and Operational Design Domain covered.

Product certification, operator qualification, task certification, and site deployment authorization shall remain distinct. A certified robot shall not automatically be authorized for every System05 building or task.

Higher certification shall not eliminate human authority, independent inspection, local code obligations, or the need to validate the active physical configuration.

False, expired, suspended, or misleading certification claims shall be subject to correction, quarantine, recall, or removal from the System05 ecosystem.

149. Third-Party Deployment, Update, Recall and Retirement

Third-party manufacturers and service providers may develop and deploy System05-compatible robotic products when they comply with applicable Interface, safety, cybersecurity, evidence, and governance requirements.

Every deployment package shall identify:

Third-party updates shall remain subject to configuration control, compatibility assessment, testing, approval, and rollback planning.

Recall procedures shall support rapid identification of affected robots, tools, software, components, sites, tasks, and evidence records. Recall scope shall be based on actual configuration and exposure rather than product name alone.

A recall may require suspension of capability, software removal, physical inspection, replacement, revalidation, or temporary operational restrictions.

Retirement shall include safe removal from service, revocation of credentials and permissions, preservation of required records, handling of stored data, disposal or reuse of components, and updating of relevant registries.

Unsupported or retired systems shall not continue consequential operation merely because they remain physically functional.

150. Robotic Governance and Incident Learning

System05 shall maintain governance structures for robotic rules, certification, deployment, incident response, and continuous improvement.

Governance shall define authority for:

Reportable events should include injuries, near misses, dropped loads, unexpected motion, structural damage, utility release, cybersecurity compromise, repeated recovery, unauthorized access, falsified evidence, and significant divergence between digital and physical state.

Incident investigation shall examine technical, organizational, procedural, human-factor, environmental, supply-chain, and governance causes. It shall not stop at identifying the last person or component involved.

Relevant evidence shall be preserved, including logs, configuration, software versions, work packages, sensor records, physical observations, approvals, training, and site conditions.

Lessons learned should be shared across the ecosystem in an appropriately protected or anonymized form. Confidentiality shall not be used to conceal systemic safety risks.

Emergency restrictions may be issued when credible danger exists, but temporary emergency rules shall later receive formal review.

Successful past operation shall not be used to dismiss new evidence of risk. System05 governance shall evolve through documented evidence while preserving its constitutional principles.
