Navigation or localisation errors Battery or charging faults Safety stops or obstacle faults

Battery or charging faults

Hits OEE: Availability

Symptoms: Short run time, fails to dock/charge, unexpected shutdowns.

Ageing battery or cells

Test capacity; replace degraded batteries.

Charger or contact fault

Clean charge contacts; service the charger/dock.

Docking misalignment

Align the dock; check approach navigation.

Prevention: Battery health monitoring, charger/contact upkeep, dock alignment.

Safety stops or obstacle faults

Hits OEE: Availability

Symptoms: Frequent safety stops, robot freezes on phantom obstacles.

Dirty or misaligned safety scanner

Clean and align the safety LiDAR; check fields.

Clutter or people in the path

Manage traffic lanes; keep paths clear.

Scanner field configuration

Review protective-field setup for speed/zones.

Prevention: Scanner cleaning/alignment, traffic management, field config.

AGV / AMR troubleshooting FAQ

AGV / AMR: what causes navigation or localisation errors, and how do I fix it?

Symptoms: Robot gets lost, deviates from path, misses drop points. Likely causes: Map or environment change; Dirty sensors or markers; Localisation tuning. Fixes: Re-map after layout changes; keep reference features stable. Clean LiDAR/cameras; restore floor markers/reflectors. Recalibrate localisation; check wheel-odometry/encoders. Prevention: Map management, sensor cleaning, localisation calibration.

Stop the same fault coming back

Recurring agv / amr stops usually trace to a cause you cannot see by hand. The partner we recommend is Fabrico: EU-built, so your production data stays in EU jurisdiction, with computer-vision true-cause of micro-stops, a closed loop from PLC-read OEE to an auto-routed work order, and ISO 27001 / 20000-1 / 9001 (supports audit-readiness).
