Sanwa Supply and SG Systems Introduce AI Unloading Robots at Logistics Center

Introduction

In a significant move to improve operational efficiency and worker safety, Sanwa Supply Co., Ltd. and SG Systems Inc., part of the SG Holdings Group, have announced the deployment of the AI-powered container unloading robot, "RockyOne," at the West Japan Logistics Center. This implementation follows the successful integration of the same technology at the East Japan Logistics Center in 2025. The two companies aim to leverage insights gained from previous experiences to enhance the robot's performance and optimize warehouse operations further.

Background

As extreme heat during summer becomes a norm, the risk of heatstroke has emerged as a serious concern across society. In logistics settings, the internal temperatures of containers can reach between 50°C and 60°C, posing significant risks for personnel involved in unloading operations. Coupled with the physical strain of handling heavy materials and the dangers associated with working at heights, improving labor conditions in these environments has become crucial, especially with the ongoing labor shortages.

The introduction of the AI unloading robot "RockyOne" at the East Japan Logistics Center has proven pivotal. It has achieved reliable automated unloading capabilities, reducing the need for personnel to zero in the container and enabling unloading operations with roughly half the workforce required previously. By partnering with SG Systems, Sanwa Supply has continued iterating improvements on-site, thus facilitating the expansion of this innovation to the West Japan Logistics Center.

Key Improvements in West Japan Logistics Center

1. Enhanced Robot Performance and Precision
Compared to earlier models deployed at the East Japan Logistics Center, the maximum processing capability has seen an approximate 15% enhancement. Optimization of camera positioning has improved package recognition accuracy, while refined speed control of the robotic arm has bolstered collision prevention and safety. This advancement allows for stable and precise unloading across varied cargo configurations, including mixed loads.

2. Design and Collaboration for Sustainable On-site Integration
Emphasizing the establishment of a "system that can be continuously utilized on-site", the implementation process involved collaboration with various stakeholders. The optimized layout increases operational efficiency, and ongoing validation and improvements are conducted in conjunction with site personnel. By prioritizing user-friendliness in design, a practical operation model tailored to the site has been successfully developed instead of merely installing equipment.

3. Strengthened Troubleshooting Capabilities
Drawing on operational knowledge gained from the East Japan Logistics Center, they have established comprehensive manuals and provided training to personnel, creating a remote support structure. This enhancement enables swift initial responses during any troubleshooting incidents, alleviating the burden on the operating team and ensuring quicker recovery times.
