1. Introduction
1.1 Purpose
The purpose of this document is to define the technical requirements for the development, deployment, and acceptance of an Autonomous Mobile Robot (AMR) for indoor industrial applications.
1.2 Scope
This specification applies to the design, integration, and testing of the AMR system to ensure it meets the defined operational, performance, and safety requirements.
1.3 Definitions and Acronyms
-
AMR: Autonomous Mobile Robot
-
FAT: Factory Acceptance Testing
-
SAT: Site Acceptance Testing
-
HMI: Human-Machine Interface
-
MTBF: Mean Time Between Failures
2. System Overview
The AMR is intended to perform autonomous tasks within an industrial environment. It will navigate a predefined map, perform material handling, and detect both static and dynamic obstacles. The robot will feature manual override and emergency stop functions to ensure operator safety.
3. System Requirements
3.1 Functional Requirements
FR-1: Autonomous Navigation
The robot shall autonomously navigate using sensor fusion (LiDAR, IMU, wheel encoders) and localize itself within a mapped environment.
FR-2: Obstacle Detection and Path Replanning
The robot shall detect static and dynamic obstacles, and replan its path with a response time of ≤100 ms.
FR-3: Human-Machine Interaction
The system shall allow manual control and override via an HMI. Emergency stop functions shall immediately halt all operations.
FR-4: Task Execution
The robot shall execute predefined tasks (e.g., material transport) autonomously and return to a charging station when required.
3.2 Performance Requirements
PR-1: Payload Capacity
The robot shall support a minimum payload of 10 kg.
PR-2: Maximum Velocity
The robot shall operate at a maximum velocity of 1.5 m/s.
PR-3: Operational Availability
The robot shall achieve an operational availability of 99%, factoring in preventive maintenance.
PR-4: Positional Accuracy
The system shall achieve a localization accuracy of ±5 mm using sensor fusion techniques.
3.3 Hardware Requirements
HR-1: Safety Sensors
The robot shall include redundant safety sensors (LiDAR, ultrasonic, etc.) to ensure human safety in the vicinity.
HR-2: Power and Endurance
The robot shall be powered by rechargeable batteries, providing at least 8 hours of continuous operation under full load.
HR-3: Computational Resources
The robot shall be equipped with a processing unit capable of handling sensor fusion, localization, and obstacle avoidance algorithms in real-time.
3.4 Software Requirements
SW-1: Remote Monitoring and Diagnostics
The robot shall support remote software updates and diagnostics via secure communication protocols (Ethernet, Wi-Fi).
SW-2: Integration APIs
The robot shall provide documented APIs for integration with existing industrial systems (e.g., Warehouse Management Systems).
4. Verification and Validation
4.1 Factory Acceptance Testing (FAT)
FAT will verify that all functional and performance requirements are met before shipping. The following tests will be performed:
-
Navigation tests to verify autonomous operation.
-
Obstacle detection and path replanning accuracy.
-
Load and speed tests to verify performance.
4.2 Site Acceptance Testing (SAT)
SAT will validate robot operation within the specific industrial environment. Tests include:
-
Performance in the intended operating environment.
-
HMI interaction and manual override functionality.
-
Safety compliance verification.
5. Compliance Standards
The robot shall comply with the following standards:
-
ISO 10218: Safety Requirements for Industrial Robots
-
ISO 13849: Safety of Machinery – Safety-Related Parts of Control Systems
-
IEC 61508: Functional Safety of Electrical/Electronic/Programmable Electronic Safety-Related Systems
-
IEC 62061: Safety of Machinery – Functional Safety of Safety-Related Control Systems
