Maintenance Procedure Library

Maintenance Procedure Library and Execution Engine

The Maintenance Procedure Library and Execution Engine is a component of the Lunar Ark's L1-MNT subsystem that provides standardized, step-by-step robotic maintenance procedures, tool requirements, and physical verification protocols. Designed for a 100-year operational lifetime, the system directs autonomous robots to execute maintenance tasks without human supervision. The library must dynamically adapt to degraded system states, unexpected conditions, and outcome deviations using dedicated error recovery routines. For novel maintenance scenarios, artificial intelligence generates new procedures, while physical verification steps confirm that each action is completed correctly before work continues.

Step-by-step robotic maintenance procedures with tool requirements and verification steps

Purpose

Provide detailed robotic-executable procedures for every maintenance task

Context

Component of L1-MNT within the Lunar Ark system

Principles

▸Standardized procedure format enables consistent robotic execution
▸Step-by-step verification ensures each maintenance action completed correctly
▸Procedure adaptation allows modification based on actual system condition
▸Error recovery procedures handle deviations from expected maintenance outcomes

Typical implementations

▸NASA maintenance procedure documentation standards (NSTS procedures)
▸ISS maintenance procedure execution system
▸Industrial robotic task programming (ROS-based procedure execution)
▸Autonomous vehicle maneuver planning and execution frameworks

Lunar considerations

▸All procedures must be executable by robots without human supervision
▸Procedures must adapt to degraded system states and unexpected conditions
▸New procedures must be generatable by AI for novel maintenance scenarios
▸Physical verification steps confirm maintenance actions were successful
