Project Overview

To address the evolving demands of the rapidly growing EC market, StockCrew aimed to establish a next-generation logistics center optimized for E-Commerce fulfillment. They introduced Autonomous Mobile Robots (AMRs) to revolutionize their warehouse management, achieving full automation of order placement operations.

Currently, StockCrew utilizes over 100 Autonomous Mobile Robots (AMRs) at their primary logistics facility, Chiba Dock, which spans 10,000 square meters. The implementation of AMRs has significantly reduced employee travel distances, enhanced operational efficiency, and improved workplace conditions.

The Problem

As the E-Commerce world grew, StockCrew faced some big challenges:

  • Rising Order Numbers: With more small EC businesses popping up, logistics needs became more varied, putting pressure on traditional warehouses.
  • Labor Shortages and Inefficiencies: Manual picking meant lots of walking, which increased labor costs and tired out workers, especially as hiring became tougher.
  • Rigid Infrastructure: Traditional warehouses had a hard time keeping up with layout changes needed for new products and seasonal peaks, risking slowdowns.
  • Higher Operational Costs: More orders handled manually meant higher costs and bottlenecks.
  • High Customer Expectations: The EC market wants fast and accurate service. Mistakes or delays could upset customers and hurt sales.
  • Tech Adoption Hurdles: Many robotic solutions required costly infrastructure changes, like floor QR codes, which StockCrew wanted to avoid.

To solve these problems, StockCrew needed an automation solution that was scalable, flexible, and easy to implement to boost their logistics operations.

The Solution

To revolutionize their warehouse operations, StockCrew adopted Syrius Technology’s Order-to-Person Pick System, a comprehensive solution combining autonomous robots, intelligent software, and flexible connectivity.

At the core of this system are the FlexSwift MAX AMRs, high-performance autonomous mobile robots designed to assist human operators by transporting multi-compartment containers. These AMRs dynamically guide operators through picking and put-away tasks, minimizing walking distances and accelerating operations.

With Syrius Technology’s Order-to-Person system, StockCrew transformed traditional, labor-intensive picking into an efficient, operator-friendly workflow. The system allows dynamic zone-based picking, cuts travel times, enhances inventory turnover, improves operational accuracy, and enables seamless adaptation to layout changes—all crucial for fast-moving EC fulfillment operations.

By simply adjusting software parameters and scaling AMR fleets, StockCrew can now rapidly respond to seasonal peaks and changing customer demands without major operational disruptions.

Although the container sizes are standardized, dividers are inserted inside the containers to create multiple types, such as 2-compartment, 4-compartment, up to 12-compartment containers.

Depending on the number of items in a B2C order, different types of containers are selected.

FlexGalaxy.AI groups orders that require the same type of container into a single task and dispatches them to the AMRs.

Through this method, StockCrew implemented multi-order picking with real-time sorting during picking, greatly improving operational efficiency.

Guided by the intuitive tablet interface, the operator moves swiftly through the picking area. As they reach the next location, the tablet displays the item to pick. The operator picks up the item, scans its barcode with a handheld scanner connected to the system, and instantly receives feedback.

At that moment, the AMR silently verifies the action: confirming if the correct item has been picked and if the required quantity is sufficient. A subtle notification appears on the tablet—either a green light for "correct" or an alert prompting the operator if there’s a mistake.

In this smooth, synchronized flow between the operator and the AMR, errors are caught immediately, ensuring that every pick is fast, accurate, and reliable, all while keeping the operator in constant motion without unnecessary steps.

The Results

By using Syrius Technology’s Order-to-Person Pick System, StockCrew greatly improved its logistics. The AMRs allowed for flexible picking, real-time sorting, and quick scaling without major infrastructure changes. StockCrew cut down on staff walking distances, boosted picking accuracy, quickly adjusted layouts, and easily expanded operations during busy times. Worker conditions got better, costs went down, and customer satisfaction increased with faster and more reliable order fulfillment.

  • 100 units of AMRs deployed

  • Shipping costs reduced by 40% to 50%.

  • Operations now require only 10 to 20 people, down from 80.

Where are we now

StockCrew uses 100 AMRs through a 5-year RaaS deal, enhancing operations with Syrius Technology to efficiently handle e-commerce logistics.

Today, StockCrew runs 100 AMRs through a 5-year Robotics as a Service (RaaS) deal. Using Syrius Technology’s advanced Order-to-Person Pick System, they enhance their operations with multi-order picking, real-time task management, and ongoing process improvements to keep up with the fast-changing e-commerce logistics needs. Their E-Commerce fulfillment centers are flexible and ready to grow with the increasing demands of the EC market.
