In a modern factory, material flow must keep pace with production without adding unnecessary traffic, waiting time, or manual handling. A lurking lift AMR moves beneath a compatible rack, trolley, or carrier, lifts it, and transports the load to the next station. Because the robot works below the load, it can automate existing workflows while keeping the transfer unit compact.
From our engineering perspective at KH Group, the main selection question is not simply how much a robot can carry. It is how the robot must move inside the real production environment. The KHC060D and KHC100D Lurking Lift AMR series is a strong fit for flexible point-to-point transport in 3C, automotive parts, lithium battery, and photovoltaic operations. The KHCX200 and KHCX300 Omnidirectional Lurking Lift AMR series is better suited to heavy loads, narrow passages, and workstations where lateral movement and precise multidirectional positioning provide clear value.
What Is a Lurking Lift AMR and How Does It Work?
A lurking lift autonomous mobile robot has a low-profile body and an integrated lifting mechanism. It travels under a load carrier, confirms its position, lifts the carrier, and moves it along a planned route. At the destination, it lowers the carrier and becomes available for the next assignment. This process supports automatic pickup, transport, delivery, and return without requiring an operator to drive a forklift for every movement.
The word “lurking” describes the robot's ability to move beneath a carrier. The load can therefore occupy the space above the AMR instead of being placed on a long towing train. This geometry is useful when a plant needs to increase transport density, keep aisles clear, or connect workstations with limited floor space. It also makes the carrier interface important. The rack base, lift contact area, center of gravity, and load stability must all match the robot and the route.
Unlike a fixed conveyor, an AMR does not require one permanent mechanical path between every process. Routes and missions can be adjusted as production changes. This flexibility is valuable for mixed-model manufacturing, line-side replenishment, work-in-process transfer, and warehouses that regularly change their storage layout. However, the best result still depends on disciplined engineering. Navigation, traffic control, safety sensing, charging strategy, carrier design, and system integration must be evaluated as one transport system.
Our Engineering View
We start with the load and process, not the robot model. We confirm the maximum total weight, carrier dimensions, floor condition, aisle width, pickup tolerance, required cycle time, and surrounding personnel traffic. Only then do we decide whether a conventional steering platform or an omnidirectional platform provides the better balance of performance, complexity, and cost.
When Should You Use the KHC060D or KHC100D Lurking Lift AMR?
The KHC060D and KHC100D series is designed for flexible material handling where a compact AMR must collect and deliver compatible carriers between production and storage points. Its modular architecture simplifies the internal structure and helps improve connection reliability and maintainability. For facilities that expect routes, stations, or production volumes to evolve, this is a practical foundation for scalable automation.
We often consider this series when the required motion is mainly forward travel and controlled turning, and when the layout provides suitable maneuvering space at stations. It can serve regular line-feeding routes, work-in-process loops, warehouse-to-line transfers, and empty-carrier returns. The goal is not to automate movement in isolation. The goal is to create a repeatable material rhythm that supports the production takt.
Typical Application Scenarios
3C Warehousing Transport
Move bins and racks between storage, kitting, and assembly areas with scheduled or demand-based missions.
Automotive Parts Transport
Support line-side replenishment and work-in-process movement across multiple production stations.
Lithium Battery Raw Material Transport
Connect incoming material, preparation, and process areas through consistent carrier transfers.
Photovoltaic Cell Transport
Automate frequent movement between controlled process steps while reducing manual travel.
Core Product Features
Fusion Navigation
QR code, laser, and texture navigation can be selected and combined to suit different zones in the same facility.
Safe and Reliable
Laser and vision sensing support 360-degree obstacle protection, with warning lights for clear status communication.
Rapid Battery Swap
A battery can be replaced in about 60 seconds, reducing waiting time compared with a long charging interruption.
Intelligent Recognition
The AMR can recognize the carrier angle, plan a pickup path, adapt to the environment, and avoid obstacles.
Fusion navigation is useful because one navigation method is not always ideal for every part of a plant. A stable open aisle, a dense rack area, and a precise pickup station may present different conditions. The ability to use QR code, laser, or texture navigation gives engineers more options when designing the route. It also helps a project team adapt the solution to the existing facility instead of forcing every zone into one approach.
Safety design is equally important. The KHC060D and KHC100D series combines laser and vision for 360-degree obstacle protection. According to the product design, the system can recognize low suspended obstacles with a minimum clearance of 5 cm, while indicator lights provide advance warning and visible operating status. These functions support safer human-machine interaction, but they do not replace a site risk assessment, traffic rules, or personnel training.
For multi-shift operation, battery management affects actual throughput. A rapid battery swap of about 60 seconds can help keep the fleet working without a long charging stop. Whether battery swapping or automatic charging is the better strategy depends on fleet size, mission intensity, shift pattern, available charging space, and maintenance policy. We calculate this during the concept stage so the energy strategy supports the required cycle time.
When Is an Omnidirectional Lurking Lift AMR the Better Choice?
The KHCX200 and KHCX300 series adds independent four-wheel drive and omnidirectional motion. The robot can translate in different directions without using the same turning arc as a conventional mobile platform. This matters when a load must be aligned beside a station, shifted laterally, or moved through a restricted area where a larger turning maneuver would interrupt nearby equipment.
The platform uses a compact structural design while providing a rated payload of up to 3,000 kg. It can support narrow-aisle travel with a minimum passage width of 1,400 mm, subject to the complete vehicle, carrier, load, safety clearance, and site conditions. These capabilities make it relevant to heavy automotive, lithium battery, and photovoltaic transport tasks where space and load are both critical.
Omnidirectional motion should still be chosen for a clear process reason. It brings the greatest value when it reduces aisle requirements, eliminates complicated multi-step positioning, or enables accurate docking in a constrained workstation. If a route has generous space and simple pickup geometry, a standard lurking lift AMR may deliver the required result with a simpler motion strategy. The correct choice is the platform that meets the process with the least unnecessary complexity.
Typical Application Scenarios
Automotive Body Welding Shop Transport
Position large carriers between welding cells where heavy loads and constrained approach paths must be coordinated.
Automotive Stamping Shop Transport
Move heavy tooling or part carriers through production areas while using lateral motion for station alignment.
Lithium Battery PACK Line Transport
Link PACK line processes with controlled carrier movement and accurate pickup or delivery positioning.
Photovoltaic Crystal Ingot Transport
Handle dense, heavy material flows between process stations where stability and route efficiency are essential.
Core Product Features
Compact Body, High Payload
A compact structure supports a rated payload of up to 3,000 kg for demanding industrial transfer tasks.
Omnidirectional Movement
Independent four-wheel drive enables translation in multiple directions and travel through passages as narrow as 1,400 mm.
Fusion Navigation
QR code, laser, and texture navigation options can be configured for the conditions of each operating zone.
Intelligent Recognition
360-degree obstacle awareness and indicator lights support early warning and safer operation around the vehicle.
The engineering benefit of omnidirectional movement is clearest at interfaces. A robot may travel along a main aisle, shift sideways into the station, align beneath the carrier, and leave without a wide turn. This can reduce dead space around pickup points. It may also simplify the station layout when loads are long, wide, or difficult to rotate inside the available footprint.
Heavy-load design also changes the project requirements. A payload figure must include the carrier and all fixtures, not only the material being transported. Engineers must check weight distribution, center of gravity, floor flatness, floor loading, acceleration limits, stopping distance, and carrier stiffness. For a 3,000 kg class application, these checks are essential to stable operation and reliable docking.
The omnidirectional series also supports QR code, laser, and texture navigation. In the same facility, the project can select different methods for different operating areas. Its 360-degree protection and status indicators improve awareness around the vehicle. As with any industrial mobile robot, the final safety concept must reflect the actual speed, payload, aisle geometry, personnel access, blind zones, and interfaces with machines or automatic doors.
How Do the Two Lurking Lift AMR Types Compare?
Both product families automate under-carrier pickup and transport, support flexible navigation design, and include safety and recognition functions. Their key difference is the motion requirement. The following table gives a practical first comparison. Final model selection should always be verified against the complete application data.

What Project Data Is Needed Before Selecting an AMR?
A reliable proposal begins with measurable site data. A short statement such as “we need a one-ton AMR” is not enough. The transport system must work at the required rate, fit under the carrier, enter every station, avoid conflicts, and remain serviceable over the planned operating life. At KH Group, we recommend preparing the following information before detailed model selection:
- Load details: maximum and normal weight, dimensions, center of gravity, fragility, and stability during acceleration or stopping.
- Carrier details: rack or trolley drawings, ground clearance, lift interface, caster behavior, structural stiffness, and positioning tolerance.
- Route details: CAD layout, aisle widths, turn areas, pickup points, slopes, floor gaps, doorways, elevators, and mixed traffic zones.
- Production details: takt time, trips per hour, operating shifts, peak demand, waiting rules, and buffer capacity.
- Integration details: fleet scheduling, warehouse or manufacturing system signals, automatic doors, elevators, machines, and station interlocks.
- Safety details: pedestrian access, crossing points, restricted zones, emergency strategy, local requirements, and site risk assessment.
These inputs help us calculate the number of robots, expected utilization, charging or battery-swap plan, station arrangement, and traffic rules. They also reveal whether omnidirectional motion truly reduces the project footprint. A successful AMR project is sized for peak operational demand, not only for an average trip.
How Can KH Group Support a Lurking Lift AMR Project?
Our work as KH Group engineers is to translate a material-flow problem into a practical mobile robot solution. We review the production layout, carrier interface, load, route, and cycle target. We then match the application to the appropriate AMR type and design the pickup, delivery, charging, and traffic logic around the real process.
For a standard lurking lift AMR project, the focus may be fleet efficiency, fast battery exchange, carrier recognition, and dependable routing between many points. For an omnidirectional project, we pay additional attention to lateral clearance, precise alignment, heavy-load behavior, floor conditions, and the geometry of each station. In both cases, commissioning should include route verification, load testing, obstacle-response checks, mission recovery, and operator training.
We also recommend planning for change. Production cells move, new products are introduced, and peak volumes increase. Modular equipment, flexible navigation, and clear system interfaces make future adjustments easier. This is why we view the AMR as part of a broader intelligent logistics architecture rather than a standalone vehicle.
What Is the Next Step for Your Material Transport Project?
Start by mapping one representative transport loop. Record the pickup and delivery points, actual load, carrier size, route length, narrowest aisle, required trips per hour, and operating shifts. This gives the engineering team enough information to identify the main constraints and compare a standard Lurking Lift AMR with an Omnidirectional Lurking Lift AMR on practical terms.
If the route is regular and has sufficient turning space, the KHC060D or KHC100D series may be the efficient choice. If the load is heavy, the aisle is narrow, or lateral positioning is necessary, the KHCX200 or KHCX300 omnidirectional series deserves closer evaluation. The final decision should be based on verified layout and cycle calculations.
