Walk into any warehouse today, and you’ll notice that the technology on the floor hasn’t kept pace with modern-day pressures of faster throughput and same-day shipping. The reliance on manual labor is still very high because most automation pitches come with the risk of downtime, torn-out racking, and a price tag that makes the CFO go quiet.

Learn how Carte+, built specifically for operations that are already running, makes warehouse automation a breeze with zero downtime. 

Warehouse Automation Is on Everyone’s Mind

In recent years, labor has become increasingly difficult to source and more expensive to retain. At the same time, brownfield warehouses have quietly absorbed growing pressure from volatile order volumes and rising expectations for faster delivery.

The challenge is that most existing warehouse systems were never designed for this level of demand. Many still run on legacy, custom-built infrastructure that struggles to adapt to modern operational complexity.

Traditional automation approaches offer limited relief. They typically require purpose-built environments, clean layouts, and dedicated floor space, conditions that are rarely achievable in a 10–15-year-old, fully operational warehouse.

As a result, operations leaders are no longer asking whether to automate. The real question is how to introduce automation without disrupting the systems that are already keeping the business running.

Brownfield Automations Come With Several Risks

Trying to modernize a building that was never designed for modern robotics, while the people inside it keep working their normal shifts, is not easy. Every decision you make has to account for what’s already there. Here’s where it tends to break down:

• Operational Downtime: Standard automation systems require pulling sections of the warehouse, sometimes for weeks at a stretch. The backlogs pile up faster than most teams expect, and during peak periods, a few days of reduced capacity are enough to damage customer relationships that took years to build. 
• Infrastructure Incompatibility: Legacy racking, uneven floors, and narrow aisles perfectly define any brownfield facility. Most automation hardware is engineered assuming a clean slate, which means implementation turns into an expensive guessing game of modifications, workarounds, and vendor calls that go unanswered. 
• Integration Complexity: A WMS that’s been configured and reconfigured over years of real operations does not constitute a plug-and-play environment. Layering a new automation system on top of it without breaking existing order flows is almost impossible. 
• ROI Uncertainty: Most automation vendors will offer a solution that is not built on your actual order history, your actual SKU mix, and your actual labor costs. Generic ROI models look convincing in a slide deck but fall apart the moment they are implemented in a live environment. 

How Carte+ Makes Automation Possible Without Downtime

Carte+ works around existing warehouse racks and does not require the traditional rip-and-replace approach. Here’s what that actually looks like in practice:

• Modular Rails: Unlike systems that demand a single standardized tote, the Carte+ retrofit system is built to work with the variety of totes and cartons that already exist in your facility. Carte+’s modular rail system attaches directly to your current rack structure and requires no floor anchoring, rack replacement, or structural work. Once the rails are in, robot shuttles pull totes and cartons from any rack level at high speed. 
• Overhead Bot Path: For brownfield facilities where the floor is already irregular, congested, or shared with forklifts and foot traffic, the Bot Path overhead track moves shuttles between aisles without using floor space at all, overcoming the need for clean, dedicated paths that most existing warehouses don’t have. 
• Synchronized Lifts: Vertical lifts connect rack levels and sync directly with the shuttle path so the system operates as one continuous, coordinated flow. There’s no handoff delay between the lift and the shuttle, no waiting for one component to finish before the next one starts. 
• Smart Software: The control software behind Carte+ handles real-time routing decisions based on live order patterns and SKU movement. Integrating seamlessly with your existing WMS and OMS, it supports batch picking, wave picking, and zone picking on-demand. 
• Digital Twin: Before Carte+ is installed, a patented physical-digital twin of your specific warehouse is built that is synchronized to your actual layout, your actual order data, and your actual operational patterns. Using this eCarte+ model, you can run historical demand, stress test it against peak season volumes, identify bottlenecks before they exist in real life, and generate ROI calculations grounded in what your warehouse actually does. 

The (false) notion that warehouse automation requires a complete rebuild causes most supply chain leaders to continue to rely on traditional picking and sorting approaches. Solutions that Carte+ eliminate the need for new infrastructure, totes, and new floors, removing months of disruption. 

Carte+ works inside the facility you already have, and can be implemented within 6 weeks, without downtime, incompatibility, and ROI uncertainty. If you’ve been waiting for automation that meets your warehouse where it actually is, this is what that looks like.

FAQs

Does Carte+ require any modifications to existing warehouse racks? 

No. Carte+ rails mount directly onto your current racking with zero rack replacement, floor anchoring, or structural changes.

How long does it take to deploy Carte+ in an active warehouse? 

Carte+ can be installed in under 6 weeks, one aisle at a time, so operations never stop during the upgrade.

What is eCarte+ and how does it help reduce automation risk? 

eCarte+ is a patented digital twin of your warehouse that validates ROI with your real order data before a single piece of hardware is installed.
