Robotics Standards (AZ-RS)

1. Overview & Scope

The AZ-RS (Aevum Zenth Robotics Standards) framework establishes mandatory technical, safety, and operational baselines for all robotic systems developed, deployed, or integrated within the Aevum Zenth ecosystem. This standard applies to:

Industrial & manufacturing automation arms
Autonomous mobile robots (AMRs) & AGVs
Human-robot collaborative (cobot) systems
Drone & aerial robotics fleets
Service & logistics robotics

ℹ️ Compliance Note

All systems must achieve a minimum AZ-RS Level 2 certification before deployment in shared operational environments. Level 4 certification is required for public-facing or unattended autonomous operations.

Standards are aligned with ISO 10218, ISO/TS 15066, IEC 61508, and internal Aevum Zenth Engineering Directives (AZ-ED-2024-09).

2. Safety Protocols

2.1 Human-Robot Collaboration Zones

All collaborative environments must implement dynamic safety zoning using the following classification:

Zone Class	Max Speed	Proximity Threshold	Required Sensors
Class A (Shared)	≤ 0.5 m/s	0.5m – 1.2m	LiDAR + Time-of-Flight
Class B (Supervised)	≤ 1.5 m/s	1.2m – 2.5m	LiDAR + Stereoscopic Vision
Class C (Restricted)	Variable	Physical barrier	Light curtains + E-stop grid

2.2 Fail-Safe & Emergency States

Systems must implement a tiered fail-safe architecture with deterministic response times:

Condition 1 (Graceful Stop): Power remains active, servos hold position. Response: ≤ 200ms
Condition 0 (Safety Stop): Power removed, controlled deceleration. Response: ≤ 50ms
Condition 00 (Emergency Stop): Immediate power cut, mechanical lock engagement. Response: ≤ 10ms

⚠️ Critical Requirement

All emergency stop circuits must be hardware-isolated and bypass software control layers. Software E-stops are not compliant under AZ-RS §2.4.

3. Interoperability Standards

3.1 Communication Protocols

Standardized messaging ensures seamless integration across Aevum's multi-vendor fleet management systems. The following stack is mandatory:

                        config/robot_middleware.yaml
                        
                    
# Mandatory transport layer configuration
transport:
  protocol: MQTT 5.0
  encryption: TLS 1.3
  qos: 1 # At least once delivery
  heartbeat: 1000 # ms

control_interface:
  standard: OPC UA
  namespace: urn:aevum.zenth:robotics:v2
  sampling_rate: 200 # Hz

command_buffer:
  max_depth: 256
  overflow_policy: drop_oldest

3.2 Data Serialization & Telemetry

All state telemetry must conform to the AZ-JSON-Schema v3.1 specification. Payloads must include:

System health metrics (CPU, thermal, joint torque residuals)
Safety state flags (condition level, barrier status)
Localization confidence scores
Timestamp (UTC, nanosecond precision)

                        telemetry/sample_payload.json
                        
                    
{
  "sys_id": "AZ-ROB-8842-X",
  "ts_utc": 1729123456789,
  "state": {
    "safety_condition": 1,
    "power_draw_w": 42.8,
    "thermal_avg_c": 41.2,
    "localization_conf": 0.987
  },
  "checksum": "sha256:a1b2c3..."
}

4. Certification Levels

Systems are audited and certified based on operational complexity, autonomy level, and environmental interaction. Certification is valid for 24 months and requires renewal with updated telemetry logs.

Level	Designation	Autonomy	Validation Requirements
L1	Remote Operated	Teleoperated / Supervised	Basic safety wiring, functional test suite
L2	Semi-Autonomous	Task-level autonomy	Collision simulation, fail-safe audit, OTA logging
L3	Highly Autonomous	Context-aware navigation	Redundant perception stack, 10k hr stress test
L4	Fully Autonomous	Unattended operation	Triple redundancy, formal verification, external audit

✓ Certification Portal

Submit telemetry archives and architecture diagrams via the Aevum Compliance Dashboard. Review cycles average 5-7 business days.

5. Implementation Checklist

Use this checklist during system integration and pre-deployment validation. All required items must pass before commissioning.

Hardware E-Stop Circuit Verification Isolate and test all physical emergency stop triggers for <10ms response.
Zone Boundary Calibration Validate LiDAR/ToF sensor alignment with physical safety perimeters using AZ-Cal tool.
Secure Boot & Firmware Signing Ensure UEFI secure boot is enabled and all binaries match Aevum signature database.
Redundant Communication Path Deploy secondary MQTT broker or mesh fallback for L3/L4 systems.
Telemetry Schema Validation Run az-rs validate --schema v3.1 against live telemetry stream.
Human-in-the-Loop Override Test Verify priority arbitration between operator commands and autonomous behavior.
