U-bot + R-bot
Front picking and back-storage system

U-bot and R-bot are combined in a ” forward-buffering and backward-storage” operation. U-bot replaces multiple equipment functions such as elevators/conveyor lines/AGVs, and improves picking efficiency and accuracy significantly compared to a separate four-way shuttle warehouse, which is the best choice for customers who seek to maximize storage density and picking efficiency.

The Advantages of U-Bot + R-Bot Storage System

The U-bot + R-bot Ultra-High-Efficiency and Ultra-High-Density Storage and Picking System uses the U-bot Omnidirectional Stacker Robot and R-bot Four-Way Shuttle to enable forward-buffering and backward-storage operations. The U-bot takes on the roles of elevators, conveyors, and AGVs/AMRs, thereby realizing a “sowing and harvesting” process of dense storage and efficient pallet-to-person picking with a single vehicle. In the meantime, when integrated with PTP Smart Warehouse Software, it achieves a “dual control” over efficiency and density, significantly enhancing picking accuracy. Therefore, it is a highly efficient, highly dense, innovative storage and picking solution.

Ultra High Storage Density

Dense storage with “distribution wall” picking positions for optimum space utilization
High space utilization with no fixed aisles

Ultra-high operating efficiency

No-unpacking put-away, fast picking, to suit more customers’needs
The rack “distribution wall” is designed with multiple single-depth positions for efficient storage and picking
R-bot inside the warehouse, U-bot outside the warehouse, efficient coordination and intelligent scheduling of multiple devices

Ultra-High ROI

2-3 year ROI
Easier to deploy and faster to delivery than a separate four-way shuttle warehouse
Compared to a separate four-way shuttle warehouse, there is no conveyor lifting equipment and costs are significantly reduced

Flexible Deployment

Replacement of conveyor lifting in front of the warehouse, more flexible operation in front of the warehouse
Flexibility to increase or decrease the number of U-bot, R-bot according to order requirements
Global planning, phased implementation, flexible expansion

In Action

Receiving Process

STEP 1

The palletized materials are sent to the inbound point by forklift, and the manual PDA performs the inbound task and requests the WMS system for inbound storage；

STEP 2

UBOT accepts the operation instruction and carries the material from the inbound point and places it in the designated position on the four-way shuttle rack；

STEP 3

The four-way shuttle vehicle travels from the standby point to the front cache point of the warehouse and elevates and transports the materials to the designated position, and the high-level materials need to be carried by the four-way shuttle to reach the high-level warehouse through the elevator；

STEP 4

After completing the inbound action, the four-way shuttle feeds back to the upper level information system, and the backend system updates the inventory information in real time.

Dispatch Process

STEP 1

According to the order or warehouse plan, WMS sends out the warehouse task instruction, and WCS system schedules the four-way shuttle；

STEP 2

Four-way shuttles carry materials to the outbound point at the end of the four-way shuttle racks and wait for outbound delivery, high-level goods can be prepared in advance through the elevator to the ground floor area；

STEP 3

U-BOT carries the materials from the 4-way shuttle rack and places them at the picking point, waiting for manual/automatic picking action；

STEP 4

After the picking is completed, the tailing pallet is returned to the warehouse for storage and the WMS system updates the information about the storage level in the storage area.
