Automated robotics inventory systems for existing warehouses

Best robotics vendors for automating warehouse inventory

If you're transitioning from manual inventory counts to an automated system while keeping your existing warehouse layout, I'd prioritize vendors that can add autonomous mobile robots (AMRs), robotic scanning, and inventory software without requiring a full warehouse redesign.

The best solution depends on whether you mainly need accurate inventory counts, automated cycle counting, location verification, or broader warehouse automation. For most existing facilities, I would evaluate inventory-scanning robots first, then compare them with mobile-robot platforms that can support wider operational workflows.

Vendors I'd put on your shortlist

• 

1. Dexory

(Best for full-warehouse visibility)

Dexory uses a ground-based autonomous robot with cameras and sensors to scan pallet locations, compare physical inventory with warehouse system records, and create a digital model of the facility. It is particularly compelling for tall racking, large distribution centers, and recurring cycle counts.

Why shortlist it: Designed to operate in existing warehouses without fixed scanning infrastructure. Its platform also identifies discrepancies and helps analyze storage utilization.hub.dexory.com+2

• 

2. Corvus Robotics

(Best for low-disruption retrofits)

Corvus One uses autonomous indoor drones to read pallet labels, verify storage locations, and flag inventory discrepancies. It can work with existing barcodes and rack layouts without requiring rack-mounted navigation markers.

Why shortlist it: Strong fit when you want to automate cycle counting without installing extensive new infrastructure or taking forklifts out of service for routine audits. Corvus also offers tracking technology for forklift movements.corvus.ai+1

3. Gather AI

(Best for flexible deployment)

Gather AI combines autonomous drone imagery and computer vision to capture inventory information and flag discrepancies. Its platform also supports camera-based inventory verification from forklifts and other material-handling equipment.

Why shortlist it: A practical option if you want to start with scanning and later extend automation to inventory movements. The company describes deployments that can begin with existing WMS data exports before moving to deeper integration.get.gather.ai+1

4. Verity

Best for automated inventory auditing

Verity's autonomous drone system scans warehouse inventory during quieter operating periods and compares the observed stock locations with WMS records.

Why shortlist it: Worth evaluating for facilities where you want recurring inventory verification while minimizing disruption to warehouse operations. Its published integration approach emphasizes exchanging the data needed for discrepancy detection without an unnecessarily complex IT project.www.verity.net+1

5. Locus Robotics

Best for broader warehouse automation

Locus deploys autonomous mobile robots to support picking, putaway, replenishment, and material movement. Its platform is designed to coordinate robots and human workers within existing warehouse operations.

Why shortlist it: Consider Locus if your objective goes beyond counting inventory to reducing walking time, automating fulfillment, and improving throughput. It is not a direct substitute for a dedicated inventory-scanning solution, so validate the counting capability separately.locusrobotics.com+1

How I'd compare them

These are qualitative assessments, not independently measured rankings. “Low” means the solution is designed to limit physical changes; it does not mean installation is guaranteed to require no modifications.

What I'd recommend for your transition

I'd start with three vendor demonstrations rather than a broad robotics RFP:

• Dexory if you want comprehensive scanning of pallet locations and better visibility into warehouse space.
• Corvus Robotics if autonomous inventory drones and minimal facility changes are the priority.
• Gather AI if you'd like to compare drone counting with retrofitting vision systems onto your existing forklifts.www.dexory.com+2

Before choosing, require each vendor to demonstrate its system in your actual rack layout and verify how discrepancies are reconciled with your existing warehouse management system (WMS).

Your evaluation should cover:

1. Inventory accuracy: Can it read your existing barcodes and correctly identify SKU, quantity, and location?
2. Integration: Can verified counts update your WMS, with an approval workflow for exceptions?
3. Operational disruption: Can it work around forklifts, workers, narrow aisles, and shift schedules?
4. Total cost: Hardware or subscription, software integration, support, maintenance, and training.
5. Measurable return: Labor hours saved, fewer inventory discrepancies, fewer stockouts, and less time spent investigating missing items.

Three questions to narrow this down

The best vendor depends heavily on your facility. What kind of warehouse are you operating?

1. Approximate warehouse size

Under 100,000 sq. ft.

100,000–500,000 sq. ft.

Over 500,000 sq. ft.

Multiple facilities

---

2. What are you counting?

Pallets in racks

Cases and individual items

Mixed pallets, bulk storage, and cases

RFID-tagged inventory

---

3. Existing warehouse management system

SAP

Oracle

Manhattan Associates

Blue Yonder

Other WMS or ERP

Spreadsheets or manual records

---

Primary objective

Automate cycle counts

Improve real-time inventory accuracy

Automate picking and material movement too

With those details, I can narrow the shortlist to the best-fit systems and identify the integration questions and cost assumptions to validate before requesting quotes.
