Yanei SGrab-R AMR Automated Reagent Storage & Retrieval System

Overview

The Yanei SGrab-R AMR Automated Reagent Storage & Retrieval System is an integrated, modular laboratory logistics platform engineered for high-precision, low-intervention management of chemical reagents, standards, biological samples, and consumables in regulated R&D, QC/QA, and clinical laboratory environments. Unlike conventional static shelving or semi-automated carousel systems, the SGrab-R employs autonomous mobile robots (AMRs) operating under a centralized orchestration layer to execute end-to-end material handling workflows — including inbound registration, dynamic slot allocation, real-time inventory reconciliation, order-driven retrieval, and traceable dispatch. Its core architecture implements a distributed sensing and control paradigm: each AMR integrates simultaneous localization and mapping (SLAM) via 2D laser LiDAR, supplemented by stereo vision and multi-axis inertial measurement units (IMUs) for robust navigation in mixed-use lab corridors and storage zones. The system operates on a deterministic scheduling engine compliant with ISO/IEC 17025 Annex A.3 requirements for sample integrity tracking and audit-ready workflow logging.

Key Features

• Modular AMR fleet architecture: Scalable from 2 to 24 units per deployment zone; each robot supports dual-mode operation — single-tube grasp (5–750 mL vials, including screw-cap, crimp-top, and snap-cap formats) and palletized carton handling (up to 12 kg payload).
• Multi-sensor fusion navigation: 1+2 composite guidance system combining LiDAR-based SLAM with real-time visual odometry and proximity-aware ultrasonic obstacle detection — enabling sub-10 mm positioning accuracy in dynamic, unstructured lab environments.
• Unified inventory control layer: Integrates RFID-tagged container identification, environmental telemetry (±0.5 °C temp / ±2% RH resolution), access event logging, and door interlock status into a single relational database schema aligned with GLP/GMP Annex 11 data integrity principles.
• Interoperable API framework: RESTful and OPC UA interfaces support bidirectional synchronization with LIMS (e.g., Thermo Fisher SampleManager, LabVantage), ERP (SAP S/4HANA), and electronic lab notebooks (ELN) — ensuring full chain-of-custody continuity across analytical workflows.
• Configurable physical infrastructure: Adaptable to ISO Class 7 cleanroom-rated enclosures, refrigerated (-20 °C to +8 °C) or ambient storage modules, and anti-static (10⁶–10⁹ Ω) work surfaces — validated per IEC 61000-6-2 EMC and UL 61010-1 safety standards.

Sample Compatibility & Compliance

The SGrab-R accommodates heterogeneous container geometries without mechanical reconfiguration: conical-bottom centrifuge tubes (15–50 mL), glass volumetric flasks (10–1000 mL), HDPE reagent bottles (30–500 mL), and nested cardboard cartons (up to 300 × 200 × 150 mm). All gripper kinematics are calibrated to ISO 8573-1 purity class 4 compressed air specifications (if pneumatic assist is deployed) and meet ASTM D4169 performance criteria for automated package handling. Regulatory alignment includes support for FDA 21 CFR Part 11-compliant electronic signatures, ALCOA+ data governance (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available), and audit trail export in CSV/CSV-TSV format for internal QA review or external inspection.

Software & Data Management

The Yanei Control Suite (v4.2+) provides browser-based administration with role-based access control (RBAC), configurable retention policies (minimum 7-year log archiving), and cryptographic hash verification of all inventory state transitions. Real-time dashboards display occupancy heatmaps, robot utilization KPIs (MTBF > 12,000 hrs), and deviation alerts triggered by out-of-spec environmental excursions or unauthorized access attempts. All transaction logs include ISO 8601 timestamps with UTC offset, digital certificate signing, and immutable blockchain-style ledger hashing (SHA-256) — satisfying EU GMP Annex 11 §4.2 and WHO TRS 996 Annex 6 requirements for data reliability.

Applications

• High-throughput pharmaceutical QC labs managing >5,000 unique reference standards and stability study samples.
• Clinical microbiology departments automating culture media and antibiotic disk inventory with temperature-governed retrieval.
• Academic core facilities supporting multi-user metabolomics and proteomics pipelines requiring strict reagent lot traceability.
• Contract research organizations (CROs) maintaining cross-client segregation via logical vault partitioning and automated quarantine workflows.
• Government reference laboratories fulfilling ISO/IEC 17043 proficiency testing program storage compliance.

FAQ

Does the SGrab-R support integration with existing LIMS platforms?
Yes — native connectors are available for Thermo Fisher SampleManager, LabWare LIMS, and Waters Empower; custom middleware development follows HL7 FHIR and ASTM E1578 standards.
What environmental conditions can the system operate within?
Standard configuration supports 15–30 °C ambient temperature and 30–70% RH; optional climate-controlled modules extend operational range to -20 °C (freezer) or +37 °C (incubator-compatible) zones.
Is robotic motion validated for ISO Class 5 cleanroom use?
While the base AMR does not hold ISO 14644-1 certification, it may be deployed in ISO Class 7 buffer zones; full cleanroom integration requires optional HEPA-filtered enclosures and non-shedding polymer gripper coatings.
How is user authentication enforced?
Multi-factor authentication (MFA) via smart card + PIN or biometric fingerprint scan; session timeouts align with NIST SP 800-63B IAL2 assurance level.
Can the system manage hazardous or flammable materials?
Yes — when installed with explosion-proof motor drives, intrinsically safe sensors (ATEX II 2G Ex ib IIB T4 Gb), and vapor-tight containment cabinets compliant with NFPA 45 and OSHA 1910.106.
