Automated storage and retrieval system for warehouse intralogistics

Project Overview

Motionwell Automation deployed an Automated Storage and Retrieval System (ASRS) integrated with SIASUN AGV fleet for a logistics operator in Singapore. The project optimized warehouse storage density and picking efficiency, replacing manual forklift operations with automated material handling.

As the authorized SIASUN AGV distributor for Southeast Asia since 2017, Motionwell brings deep expertise in AGV fleet deployment, traffic management, and integration with warehouse management systems.

System Components

ASRS Racking and Retrieval

The ASRS installation uses double-deep selective racking reaching 12 meters in height with 8 storage levels, increasing cubic storage utilization by over 60% compared to the previous conventional racking layout:

  • Stacker crane with telescopic fork for double-deep pallet access, rated for 1,500kg per pallet position
  • Multi-deep storage configurations for high-volume SKUs with FIFO (first-in-first-out) lane management
  • RFID-tagged locations using UHF passive tags at every storage cell for real-time inventory tracking
  • Siemens S7-1500 PLC controlling crane sequencing, with Profinet communication to the fleet management server

SIASUN AGV Fleet

Motionwell deployed a fleet of 8 SIASUN AGF-L15 laser-guided AGVs, each rated for 1,500kg payload capacity. The AGVs replaced manual forklift operations on all transport routes between the ASRS, receiving docks, and shipping staging areas:

  • Laser-guided navigation (LiDAR SLAM) with RFID floor tags at decision points for position verification
  • Magnetic tape guidance along primary travel lanes with laser-based free navigation in open zones
  • SIASUN RoboRoute traffic management system coordinating multi-vehicle routing, deadlock avoidance, and intersection priority scheduling
  • 4 opportunity-charging stations positioned along travel routes, enabling continuous 24/7 operation without dedicated charging downtime
  • Fleet scalable to 20+ vehicles on the same traffic management server without software license changes

Integration Architecture

The system integrates with the customer’s existing SAP EWM warehouse management system via standard RFC/BAPI interfaces:

  • WMS interface for inbound/outbound work order management and task prioritization
  • RFID-based inventory verification at every handoff point (dock, ASRS entry, staging)
  • Web-based fleet management dashboard with real-time AGV position, battery status, and task queue monitoring
  • Exception handling workflows with automatic rerouting and manual override via handheld terminals

This project demonstrates Motionwell’s robotics integration and custom machine design expertise for the warehouse & intralogistics industry.

Challenge

A logistics operator needed to optimize warehouse storage density and picking efficiency. Manual storage and retrieval was labor-intensive and error-prone, with growing demand exceeding manual capacity.

Solution

Motionwell deployed an ASRS system integrated with SIASUN AGV fleet for automated pallet transport. RFID-based inventory tracking with traffic management ensures efficient material flow throughout the warehouse.

Outcome

Significantly increased storage density and retrieval speed. AGV fleet handles pallet transport between ASRS and shipping/receiving docks. RFID tracking provides real-time inventory visibility.
