Toden Logistics Implements Mujin's Robotic Case Picking Automation Solution 'MujinRCP'

Logistics Automation with MujinRCP

Mujin Japan, a comprehensive automation technology company, has launched its robotic case picking automation solution, 'MujinRCP,' at the Central Branch of Toden Logistics (Ota-ku, Tokyo), under the supervision of NX Shoji Co., Ltd.

In this system, the integrated automation platform 'MujinOS' controls arm robots and 17 Automated Guided Vehicles (AGVs) to automate the case picking of diverse materials used in power facility construction. Logistics supporting power infrastructure is a critical area where mis-shipping or delays can impact social infrastructure maintenance. This initiative is a leading case study of advancing 'Lifeline Logistics' through physical AI.

### Background: Challenges Toden Logistics Aimed to Solve

Toden Logistics needed to accurately pick a wide variety of materials, facing the following challenges with manual operations:

- Dependence on heavy manual labor: Need to pick cases with diverse shapes and weights. - Personalization of shipping work: Requiring specialized knowledge, leading to quality risks in the absence of experts. - High inspection load to prevent mis-shipping: High shipping accuracy requirements led to excessive inspection burdens.

### System Features: Next-Generation Case Picking Automation

1. Automation of High-Mix Picking with Physical AI: Robots autonomously execute palletizing using 3D vision and proprietary physical AI technology (MujinMI). 2. Ease of Implementation without Fixed Equipment: MujinOS integrates and controls arm robots, AGVs, and pallet stackers, enabling installation even in limited spaces. 3. Reduction of Inspection Work and Mis-shipping Risks via Logistics DX: Operations, inventory, and shipping performance are visualized and centrally managed on a digital twin.

### Results: Strengthening Logistics BCP in an Era of Labor Shortage

The initiative has resulted in the following benefits:

- Case material handling: 90% automated (at Central Branch) - Picking personnel: Reduced from 4 to 1 person - Shipping inspection work: Eliminated - Safety: Reduced industrial accident risks through person-vehicle separation - Warehouse operation enhancement: Strengthened stable supply system

Toden Logistics has built an automated system that allows for continuous high-precision shipping even with limited personnel. This has led to the strengthening of logistics BCP, enabling stable shipping while maintaining and improving quality despite labor shortages.

### Future Outlook

MujinRCP enables flexible automation tailored to site needs by integrating control over general-purpose equipment. Moving beyond traditional automation that requires adapting sites to fixed facilities, it promotes optimization in logistics sites where volume and items change daily.
