About 6 River Systems

6 River Systems became part of Ocado Group in May 2023. Founded in 2015 and based in Massachusetts, USA, 6 River Systems provides medium density warehouse automation solutions to the logistics and retail sectors.

Central to this is 6 River's Autonomous Mobile Robot (AMR) product named ‘Chuck’, which provides automated assistance in a warehouse, working collaboratively alongside human operators. Chuck robots are currently deployed in over 100 warehouses worldwide with more than 70 customers.

CHUCK AMR

Boost Warehouse Productivity With Chuck AMR

Exceed customer expectations, grow profits, and reduce risk with our regular-density warehouse automation system, combining advanced fulfillment algorithms with Chuck autonomous mobile robots (AMRs).

Chuck helps your associates work faster, guiding them through their work zones—to minimize walking, help them stay on task and work more efficiently. Chuck is a warehouse automation solution that can be used to improve cutaway, picking, sorting and returns tasks.

Chuck doesn't need wires, cables or stickers to move around. State-of-the-art sensors help it navigate in any warehouse without any new infrastructure. Chuck is aware of its surroundings, moving swiftly around boxes and racks and slowing down in proximity to equipment or people. 

The autonomous mobile robot can be used on all types of warehouse floors, including rack-supported mezzanine.

Chuck can run 24/7 with the latest in battery technology for rapid recharging. With large, modular and multi-level workspaces, Chuck is the most configurable autonomous mobile robot in the industry and can handle up to a 200lbs / 90.7kg payload.

Key Benefits

Chuck AMR
Reduce Cost Per Unit Shipped–Grow More Profitably

Achieve higher throughput by leveraging our patented, system-directed algorithms rather than relying on associates’ judgment to calculate optimal task allocation and path planning.

Chuck AMR
Maximize Your Operations With Unparalleled Capacity, Flexibility & Insights

Reduce cost per unit shipped with the highest throughput per bot, easily deploy rental CHUCKs for peak or add capacity to meet demand across your network. Resolve operational bottlenecks faster so your managers can work on higher-value tasks.

Chuck AMR
Address Labor Challenges While Increasing Productivity

Our system-directed approach allows you to better predict capacity and plan your operations. A simple user interface means associates can start picking in minutes. Reduce employee fatigue from working with heavy carts–CHUCK does all of the heavy lifting and navigation.

Chuck AMR
Reduce Risk Today And Tomorrow

Improve predictability with an industry leader with thousands of robots in the field at over 100 sites across North America and Europe.

Frequently Asked Questions

Common questions about the Chuck AMR (Autonomous Mobile Robot).
How does system directed picking work? Chuck AMR facilitates system-directed picking, carrying items for human operators and traveling between zones to maximize efficiency and minimize long walks. Cloud-based fulfilment execution software (FES) coordinates Chucks to work seamlessly with associates across shifting work zones via their touchscreen displays. Real-time data is processed to optimize task allocation and routing, enhancing warehouse operations like putaway, picking, sorting, and packing. For tasks unsuitable for a Chuck, the Mobile Fulfillment app optimizes other manual picking scenarios.

FES works with any WMS software to enhance its capabilities, increasing operational productivity and reducing costs.
How can this small "cart" be as efficient as my large manual cart? Chuck, our autonomous mobile robot, can be 2-3 times more efficient than large manual carts that can weigh over 300 pounds when fully loaded. Chuck eliminates long pick walks by bringing work to operators and autonomously delivers fully loaded carts to take-off points, reducing long walks between induct, pick, and take-off areas, improving efficiency by 20-40%. Chuck also reduces in-aisle walking, as our cloud-based services (FES) assign work to Chuck in real-time and identify batching opportunities, reducing steps between picks and in-aisle walking by 30% or more. Finally, Chuck's system-directed approach, intuitive user interface, hands-free scanner, and optimal path setting reduce task times by 20-40%, eliminating the fatigue of pulling heavy carts.
How are you different from other mobile robotic solutions? Unlike goods-to-person robots, which require extensive infrastructure and high costs, Chuck delivers immediate impact with consistent picker performance and minimal training time. Unlike simple transport robots, Chuck optimizes pick rates and accuracy with picking across shifting work zones.. Unlike swarm-based systems, Chuck's intelligent order allocation and intuitive interface enhance efficiency without congestion. Key differentiators include high capacity, dynamic zone picking, intuitive UI, real-time insights, and cloud-based software (FES), ensuring maximum productivity and cost-efficiency. FES orchestrates workflows, integrates with various devices, and streamlines operations, making it the backbone of OIA's Chuck AMR offering.
Do I need to follow the Chuck around the whole time? No. Associates only follow Chuck in their assigned area (zone). Chuck travels autonomously, without an associate, from induct to active, between zones, from active to takeoff and from takeoff back to induct.
What changes to my infrastructure do I need to make/install to deploy an AMR solution? No infrastructure changes are required to deploy Chuck, which is one of the biggest appeals of the solution. We offer a drop-in replacement to your cart picking operation using your existing WiFi network and with no on-premise servers needed.
How many Chucks do I need for my warehouse? The number of Chucks required depends on your warehouse size and layout, order volumes and profiles, the types of products being shipped, and your current workflow. To determine your specific needs, please contact us, and one of our solutions executives will follow up with you.
Can you install different carton configurations? Yes, the system supports various container types and sizes, including totes, totelets, trays, bins, and shipping cartons. Advanced cartonization logic selects the optimal container(s) for your orders.
Do you integrate with any WMS? Yes, we integrate with any host system, including ERP and WMS software. We have experience with leading providers and custom systems. Our standard API uses JSON and HTTPS, or we can interface with various message formats (CSV, fixed width, XML) and transport methods (file, SFTP, HTTP, sockets). To get started, we need only task (picks or putaway) and product information. Our systems integration experts will help define the right specifications for your installation, offering additional messages as needed.
What is the improvement in pick rates? Our system can more than double manual pick rates and offers additional benefits such as improved accuracy, SLA attainment, reduced training overhead, streamlined wave planning, and lower employee turnover.
Can Chuck support putaway? Yes. Chuck supports putaway, pick, sort and packout.
How long does it take to charge? With advanced battery technology for rapid recharging, Chuck doesn't tire easily and can run 24/7 with minimal interruptions. Depending on payloads, Chuck can operate for 12+ hours without needing a charge. Our cloud software autonomously manages optimal charging, ensuring the fleet meets your daily throughput requirements without manual intervention.
Does my team need special skill sets to use Chuck? No, in fact, associates can be fully trained on Chuck in a matter of minutes. This enables you to consider hiring individuals with varying levels of experience or abilities, who may have previously faced barriers to employment due to physical health limitations.
What is the difference between Chuck and Chuck +? Chuck + is operationally identical. Chuck + is a wider version/configuration of Chuck AMR. Chuck is 23.75 in / 60 cm wide while Chuck + is 29.75 in / 75cm wide.
