Keep evidence with every maintenance action

Separate symptoms from causes, preserve configuration state and verify the robot before returning it to use.

Maintenance workflow

Inspect→Capture evidence→Isolate→Repair or update→Verify→Record

Area	Purpose	Start here
Routine maintenance	Detect wear, looseness, contamination and drift before failure	Routine maintenance
Diagnosis	Read states and logs, reproduce symptoms and isolate one subsystem	Diagnosis
Common faults	Follow evidence-led triage by subsystem	Common faults
Repair	Restore a known configuration with appropriate parts and records	Repair
Updates	Apply versioned software or firmware with a tested rollback	Updates

Before service, make the robot safe against unintended motion and stored energy. After service, repeat the affected acceptance checks and record parts, revisions, commits, configuration changes and results.

Current scope

These pages define the documentation and verification structure. Procedures remain planned until tested against an identified hardware revision and release.
