When sourcing AMRs, you must prioritize Navigation Technology (prefer SLAM - Simultaneous Localization and Mapping over simple QR codes for flexibility). Key metrics include Payload Capacity (ensure a safety margin of 20%), Battery Life and Charging Efficiency (look for Automatic Mapping and Auto-charging capabilities), and Positioning Accuracy (typically ±5mm to ±10mm for high-precision tasks). Additionally, verify Software Integration capabilities, specifically compatibility with WMS (Warehouse Management Systems) and ERP systems via API or SDK.
