U-Bot Narrow Aisle Storage System

The Narrow Aisle Storage System, featuring the U-bot Omnidirectional Stacker Robot, efficiently manages both entire-pallet storage and split-case picking operations. Compared to traditional counterbalanced stacker AGVs, it improves storage density by 30%, because the U-bot works in much narrower aisles. Designed to operate in extremely narrow aisles, it is easy to deploy and delivers rapid results. This makes it an ideal solution for customers aiming to upgrade from conventional manual forklift operations to enhance storage density and overall efficiency.

Application scenarios: Warehouse clear height up to 10 m; large number of SKUs; relatively high storage density, inbound and outbound efficiency, and picking efficiency.

Applicable industries: Supermarkets, retail, 3PL, manufacturing, energy and more.

System: U-bot Omnidirectional Stacker Robot + PTP Smart Warehouse Software + Multi-Functional Workstation + Pallet Racks

Store-organiser bins on pallet bases turn a bulk pallet ASRS into an e-commerce picking ASRS: the system brings the bins to the picker, so individual items are picked without anyone walking the aisles.

6-Way Shuttle AI Warehouse

AI Warehouse Storage & Picking System

The AI Warehouse is an integrated pallet storage and picking solution based on the deep integration of AI and robotics. By embedding AI Agent capabilities into the WMS and RMS systems, and using 6-way pallet shuttles as the core smart warehouse robots, it enables fully automated operations across the entire process, from inbound and storage to picking and outbound. It offers high density, high efficiency, high intelligence and low cost, dynamically optimising storage location allocation and operational efficiency for flexible warehouse upgrades.

Application scenarios: Warehouse net height up to 30 m; unlimited SKUs; high storage density, inbound and outbound efficiency, and picking efficiency.

Applicable industries: 3PL, manufacturing, retail, shoes and clothing, supermarkets, e-commerce, food and more.

6-Way Pallet Shuttle Dense Storage System

The combination of the R-bot 4-way pallet shuttle and the H-bot 2-way vertical shuttle suits dense storage of whole-pallet inbound and outbound, or a small amount of picking, with significant advantages in cost, efficiency and density. The H-bot can be deployed at any position inside or outside the warehouse, with flexible efficiency configuration, fast delivery and easy maintenance, making it the best choice for customers seeking maximum storage density and inbound and outbound efficiency.

Application scenarios: Warehouse net height up to 30 m; unlimited SKUs; high storage density and inbound and outbound efficiency; general picking efficiency.

Applicable industries: Food, manufacturing, cold chain, energy, chemical industry, building materials and more.

System: R-bot 4-way Pallet Shuttle + H-bot 2-way Vertical Shuttle + PTP Smart Warehouse Software + Multi-Functional Workstation + Pallet Racks

Because it eliminates aisles altogether, the 6-Way Shuttle AI Warehouse improves storage density by around 70%.

Store-organiser bins on pallet bases turn a bulk pallet ASRS into an e-commerce picking ASRS: the system brings the bins to the picker, so individual items are picked without anyone walking the aisles.

System Advantages

Maximise Space

• Unrestricted by space: adapts to any warehouse layout and uses every inch of space.
• Pallets can be placed in any location, maximising storage capacity.

Maximise Efficiency

• Shuttles move to any location, with every movement following the optimal path.
• The inbound station can be set up anywhere on the ground floor, with pallet outbound in just 5 seconds.
• Redesigned rack rails allow a travel speed of 2.5 m/s in any aisle.

Smarter Decision-Making

• Smart Storage: automatically assigns storage locations and aisles as SKU volume and demand change.
• Smart Realign: automatically prepares orders based on order waves and storage situation.
• Smart Operations and Maintenance: predictive maintenance, autonomous monitoring and anomaly detection.

Lowest Cost

• Higher density and efficiency lower the cost of equipment and facilities per storage location.
• Standardised products significantly reduce delivery costs.
• Operating, maintenance, renovation and expansion costs are significantly reduced.
