Why Automate Now
The Fulfillment Center Has Changed
The warehouse of the 90s was built around pallet rack, lift trucks, aisles and people walking to pick orders. Today, labor shortages and rising demand for e-commerce residential deliveries are changing that model, and modern fulfillment centers are too large for people to travel efficiently for rapid picks.
In the automated fulfillment center, inventory is stored on mobile shelving units and moved by goods-to-person robots. People stay at the pick to light put wall to scan and pack, and ROI is realized in less time.
Industries leading the shift: semiconductors and photonics, life sciences, automotive, food and consumer goods, and clothing.

Engineered for Automation
Built for Constant Robot Transport
Integrators trust Western Pacific for superior engineering. As the original boltless shelving manufacturer, we offer a strong, custom-engineered product designed specifically for the rigors of robot transport.
- Reinforced Base: Configured to match your AMR, with space for a QR code and heavier tubing available.
- Reinforced Legs: Built at the height your robot requires.
- Product Containment: A raised shelf lip on all four sides of every level.
- Adjustable Levels: Add, remove or reposition levels as your SKUs change.
- Decking Options: Medium density fiberboard, steel hemmed or wire shelves.
- Structural Rigidity: Designed for vibration resistance and long service life.
Adaptable Over Time
Start Manual. Automate When Ready.
RiveTier AMR Racks work as standard shelving today and ride on your robots tomorrow. Unlike fixed conveyor systems, you can reconfigure aisles, add lanes or increase capacity as your operation grows, without ripping out existing infrastructure.
Narrower aisles and robot navigation increase storage density without expanding your building, while your team focuses on value-add work instead of walking.

FAQ
Frequently Asked Questions
What is the RiveTier AMR Rack and how does it contribute to warehouse automation?
The RiveTier AMR Rack is the specialized, mobile shelving unit engineered to be transported by Autonomous Mobile Robots (AMRs). It functions as the crucial physical interface between stored product and the robot. By enabling robots to retrieve and transport entire racks, it eliminates the need for human pickers to walk miles across the warehouse.
Can the rack be customized to fit my specific AMR model?
Yes. The RiveTier AMR Rack comes in a variety of sizes and configurations. WPSS works with integrators to ensure the base and overall design are precisely engineered to match the specifications and attachment mechanisms of your robot platform.
Is the robot included with the rack?
No. The AMR is not included with the rack. We partner with your automation provider to make sure the rack fits your robot.
Can AMRs move full pallets?
Yes. Our Mobile Pallet Movers let your AMR transport pallet loads and are available with corner nubs or high posts. Stationary Transfer Platforms and rails are also available.
What shelf materials are available?
Mobile shelving units are available with medium density fiberboard, steel hemmed or wire shelves.
Can I install racks now and add robots later?
Yes. The racks work as standard shelving until you are ready to automate, so you can scale at your own pace.
Do you work with system integrators and dealers?
Yes. WPSS is an engineering company that specializes in supporting the integrator. Send a general layout and robot specs, and our team will return a bill of materials with freight, lead time and pricing.
Your Warehouse Shouldn’t Fight Your Future
Whether you are evaluating a robot project or want to future-proof your facility, our automation team can review your layout and robot specs, or help you start a phased, robot-enabled upgrade.
Note: AMR not included with rack.
