How AMR-Based Automotive Intralogistics Connects Every Production Stage

Automotive material flow is rarely a single transport problem. It is a connected system that starts at receiving, passes through storage and component production, and finishes beside the assembly line. When one link is slow, unpredictable, or difficult to trace, the effect can reach the entire plant.

Executive summary: KH Group designs automotive intralogistics solutions around the actual load, process rhythm, route constraints, and system interfaces of each workshop. By combining lurking lift AMRs, omnidirectional lurking lift AMRs, vision gates, workstations, iWMS, and upper-level production systems, we help plants automate RDC receiving, RDC warehousing, stamping, body welding, and final assembly while improving material accuracy, visibility, safety, and responsiveness.

From an engineer's point of view, the goal is not simply to replace a forklift or tugger with a mobile robot. The goal is to create a material flow that knows what to move, when to move it, where it must arrive, and how to recover when production conditions change. That requires the vehicle, carrier, traffic logic, workstation, and software layer to operate as one solution.

Why Is Automotive Intralogistics Difficult to Automate?

Automotive plants handle a broad mix of pallets, bins, racks, stamped panels, body parts, interior components, and line-side kits. The loads vary in size and center of gravity. Delivery frequencies also change with vehicle model, production shift, and line-side inventory policy. A solution that works in an RDC may not be suitable for a stamping die-side route or a welding fixture area.

Our engineers typically see four recurring pressures. First, manual material handling creates a continuing labor burden and depends heavily on operator experience. Second, mixed-model production demands greater flexibility than fixed conveyors can easily provide. Third, material shortages or mismatches can stop a production line. Fourth, mixed traffic involving people, forklifts, and carts raises safety and coordination requirements.

Which Lurking Lift AMR Fits the Automotive Task?

Lurking lift AMRs travel beneath compatible racks or carriers, lift them, and transport them to the assigned destination. This approach separates the vehicle from the load carrier, so one AMR can serve many racks. It is well suited to repetitive point-to-point transport, supermarket replenishment, RDC movements, line feeding, and empty-rack returns.

For standard routes with adequate turning space, the KHC060D and KHC100D series provide a practical foundation. Where long racks, narrow aisles, precise lateral positioning, or complex docking geometry must be handled, the KHCX200 and KHCX300 omnidirectional series offer greater movement flexibility. The correct choice depends on the complete transport envelope, not only the nominal payload.

Lurking Lift AMR - KHC060D & KHC100D Series

For automated rack lifting and transport in receiving, storage, line feeding, and empty-carrier return routes.

Omnidirectional Lurking Lift AMR - KHCX200 & KHCX300 Series

For long loads, restricted spaces, lateral movement, accurate alignment, and demanding automotive workstation interfaces.

How Can AMRs Support Five Core Automotive Processes?

We divide the plant into process zones because every zone has a different task trigger, carrier, interface, and definition of success. The following five-stage framework helps engineering teams evaluate the complete flow rather than installing isolated vehicles.

01RDC Receiving

At receiving, supplier materials are unloaded, identified, checked, and transferred into storage. Conventional operations often rely on forklifts and manual code scanning. This creates labor dependency, slow confirmation, and inconsistent data entry during busy receiving windows.

A KH Group solution can combine a lurking lift AMR, automatic code-reading vision gate, and iWMS. After a load is placed on a compatible carrier, the AMR accepts the receiving task and transports it through the vision gate. The gate reads the material identity automatically, while iWMS associates the physical load with its digital record and assigned destination.

1. The carrier is prepared at the receiving buffer.
2. The AMR collects the loaded carrier.
3. The vision gate reads and verifies the material code.
4. iWMS confirms the record and directs the AMR to the correct inbound position.

02RDC Warehousing

RDC warehousing must support fast inbound put-away, accurate storage, picking, staging, and timely outbound supply. Manual systems often depend on workers using handheld devices to confirm each action. As the number of SKUs and delivery waves increases, labor cost rises and operating performance becomes more difficult to standardize.

Here, a lurking lift AMR works with a workstation and iWMS. Staff complete the required selection or confirmation at the workstation. The system then releases a transport task, and the AMR retrieves or delivers the appropriate carrier. This separation lets operators focus on value-added selection and verification while the AMR handles repetitive travel.

1. The operator completes shelf or material confirmation.
2. iWMS generates an inbound or outbound movement task.
3. The AMR retrieves the correct carrier and moves it through the warehouse.
4. The carrier arrives at the workstation, buffer, or next process point.

03Stamping Shop

Stamping is one of the earliest production stages for vehicle body components. Racks may differ significantly in length and width, and the aisle around presses, buffers, and robotic stations may provide little turning space. Traditional transport also involves repeated manual travel and careful positioning near equipment.

An omnidirectional lurking lift AMR can move laterally, rotate, and align with the required interface without the wide turning arc of a conventional vehicle. This makes it useful for transporting long stamping racks from buffer storage to the line and returning empty carriers. Mechanical interfaces and system interlocks should be validated during detailed design.

1. The AMR collects an empty or loaded stamping rack.
2. The fleet system assigns the route and manages intersection priority.
3. The AMR aligns with the press-side or robotic loading point.
4. After unloading, the empty rack is returned to the designated buffer.

04Body Welding Shop

Body welding joins stamped components into the vehicle body structure. A missed, incorrect, or late material delivery can affect automated cells and line continuity. The workshop may contain fenced robotic areas, narrow access paths, multiple buffers, and several rack formats.

Depending on rack geometry and route conditions, KH Group can combine standard lurking lift AMRs and omnidirectional lurking lift AMRs. The dispatch system pulls the correct material from the preparation area, delivers it to the designated line-side point, and organizes the return of empty racks. Multilevel caching can help absorb short-term production variation without overloading line-side space.

1. Material is prepared and associated with the production demand.
2. The dispatch system releases a prioritized delivery task.
3. The selected AMR transports the rack to the assigned welding cell.
4. Empty carriers return through a controlled reverse-logistics route.

05Final Assembly Shop

Final assembly brings together vehicle body, powertrain, seats, instrument panels, doors, trim, and many other components. Delivery timing is critical because line-side space is limited and the material sequence must match the production plan. Manual transport can become increasingly difficult as model variety grows.

In this area, lurking lift AMRs can move full carriers from preparation zones to the line and return empty carriers after use. When connected with iWMS and the upper-level production system, tasks can be released according to demand, route availability, and buffer status. The system supports orderly replenishment and reduces dependence on repeated manual towing.

1. Materials are completed and staged in the preparation area.
2. The system calls an AMR according to line-side demand.
3. The AMR delivers the loaded carrier to the specified station.
4. After use, the AMR returns the empty carrier to the preparation area.

How Do the Five Processes Compare?

What Do Real Automotive AMR Projects Look Like?

Real deployments show why a complete-system approach matters. Vehicle quantity is only one part of the project. The business result also depends on carrier standardization, host-system integration, traffic management, task logic, and a phased commissioning plan.

Automotive OEM RDC Automated Logistics

In an OEM RDC, lurking lift AMRs can connect receiving, intelligent matching, automatic put-away, order-driven retrieval, and workstation picking. This replaces repeated manual travel with system-directed movement and makes material status easier to visualize and review.

Expected operational value: lower manual transport demand, improved material data visibility, faster inventory checks, and reduced interaction between workers and conventional vehicles.

New Energy Vehicle OEM Body Welding Logistics

Body welding requires continuous component supply across distributed stations. A mixed fleet can respond to production tasks and deliver the required rack to the correct position. The solution can interface with robotic cells, the upper-level system, and peripheral equipment so material arrives with minimal manual intervention.

Expected operational value: better line continuity, lower manual handling intensity, and reduced safety exposure around material delivery routes.

Steel Cord Processing Project for an Automotive Parts Group

Steel cord processing involves material transfers among storage, drawing, heat treatment, and stranding processes. Multiple AMR types can work with MES, iWMS, WCS, and scheduling software to coordinate task release, carrier allocation, and transport between equipment areas.

Expected operational value: reduced manual movement, digital material records, visible process status, and more consistent cross-process supply.

Smart Manufacturing Logistics Center for an Automotive Lighting Park

Automotive lighting production may require a large fleet serving storage, goods elevators, roller doors, assembly areas, and line-side stations. Central dispatch helps distribute tasks, manage congestion, and coordinate charging while maintaining a traceable material flow across the plant.

Expected operational value: improved logistics efficiency, lower inventory pressure, automated return of empty containers, and flexible scheduling for different production processes.

What Should Be Confirmed Before an Automotive AMR Project?

A successful project begins with on-site data. Before defining vehicle quantity or route layout, our engineers recommend documenting the material flow at task level. This gives both sides a common baseline and makes later acceptance criteria measurable.

Acceptance criteria should cover more than whether a vehicle can complete one route. We recommend defining throughput, docking accuracy, task response, system availability, charging behavior, exception recovery, manual override, and safety validation. A phased rollout allows the project team to stabilize carriers and process rules before fleet expansion.

Why Work with KH Group on Automotive Intralogistics?

KH Group approaches mobile robotics as an engineering and integration project. We evaluate the process, recommend the appropriate AMR type, review carriers and workstations, plan traffic and charging, and coordinate software interfaces. This helps customers avoid fragmented equipment that performs individual movements but does not support the production system as a whole.

Our objective is a solution that can be deployed with clear process ownership and expanded as production needs evolve. Whether the first target is an RDC, stamping area, welding workshop, or final assembly line, we focus on reliable material flow, practical integration, and maintainable operation.
