DuaDual-Station Tote Four-Way Shuttle Robot for Faster Tote Handling

In tote ASRS projects, storage density is only one part of the challenge. As order frequency increases, warehouses also need faster tote retrieval, smoother tote flow, and more stable goods-to-person picking.

DELIECN Dual-Station Tote Four-Way Shuttle Robot is developed for high-throughput tote storage and retrieval. Compared with a single-position shuttle robot, the dual-station design allows the robot to handle two tote positions in one operating cycle, helping reduce unnecessary empty travel and improve tote movement efficiency inside the racking system.

With up to 5 m/s travel speed, ±2 mm positioning accuracy, and 100 kg load capacity, the robot is suitable for high-SKU warehouses where tote response speed and positioning stability directly affect picking efficiency.

Dual-Station Design for Higher Efficiency

The biggest feature of this robot is its dual-station structure. With two tote positions, the robot can support more efficient task combinations during storage, retrieval, transfer, and return operations.

In suitable task scenarios, the robot can complete tote handling with fewer unnecessary movements. This helps improve tote flow continuity inside the ASRS and reduces waiting between storage locations, lifters, conveyors, and picking stations.

For customers, this means:

• faster tote handling
• reduced unnecessary empty travel
• better task continuity
• better support for high-frequency picking
• improved system throughput

This makes the product especially valuable for warehouses where tote flow is intensive and picking response time matters.

High-Speed Four-Way Movement Inside the Rack System

The robot can travel along both main and sub-aisle directions inside the racking system. It is not limited to moving forward and backward in one storage lane.

This four-way movement supports lane switching, multi-aisle access, and flexible storage location allocation. With lifters and conveyors, the robot can also support multi-level tote storage and retrieval.

The robot’s travel speed of up to 5 m/s helps the tote ASRS respond faster to storage, retrieval, and goods-to-person picking tasks. For high-SKU warehouses, this is important because order structures and SKU demand change frequently.

Multiple Task Modes for Tote ASRS

Different tote ASRS projects may require different operation flows. DELIECN dual-station tote four-way shuttle robot can support multiple task modes according to project configuration, including:

• inbound storage
• outbound retrieval
• tote transfer
• return-to-storage
• goods-to-person picking supply
• storage location adjustment

This helps the system better adapt to different tote flow patterns and picking rhythms, instead of relying on one fixed movement logic.

Accurate Positioning for Stable Transfer

Speed is important, but in tote ASRS, accuracy is just as critical. Totes must transfer smoothly between rack locations, lifters, conveyors, and picking stations.

DELIECN dual-station tote four-way shuttle robot supports ±2 mm positioning accuracy, helping reduce tote misalignment and improve long-term system reliability.

This is especially important in high-throughput systems, where even small positioning errors may affect transfer continuity and workstation supply.

Suitable Applications

The dual-station tote four-way shuttle robot is suitable for:

• e-commerce fulfillment
• pharmaceutical distribution
• retail and apparel warehouses
• spare parts storage
• electronics and components warehouses
• cosmetics and daily goods storage
• manufacturing material preparation

It is especially suitable for high-SKU, high-frequency, goods-to-person picking scenarios.

The product is not only designed to move faster. Its core value is helping the tote ASRS operate with fewer unnecessary movements, better task efficiency, and more stable tote delivery.
