The continuous surge in market demand has not only fueled the rapid development of China’s logistics mobile robot industry but has also catalyzed the gradual formation of a specialized domestic supply chain for core components. This article provides a high-level industry analysis, classifying the essential hardware and software components that constitute logistics mobile robots, examining their market landscape and technological trajectories, and offering recommendations for sustainable and healthy future development models for the industrial chain.
1. An Overview of China’s Logistics Mobile Robot (AGV/AMR) Industry Development
Logistics mobile robots, encompassing both AGVs (Automated Guided Vehicles) and AMRs (Autonomous Mobile Robots), are pivotal equipment for enabling flexible manufacturing, assembly, and automated logistics handling. In recent years, driven by the national “Manufacturing Power” strategy and continuous advancements in smart manufacturing policies, there has been a pressing need for enterprises to upgrade traditional industries and enhance equipment automation and intelligence to achieve high-quality development. This demand has significantly increased the market need for logistics mobile robots, propelling the industry’s swift expansion.
The scaled development of China’s logistics mobile robot industry began to take shape around 2012. The explosive growth of e-commerce and express delivery sectors acted as a catalyst, spurring vigorous industry development. The application of logistics mobile robots expanded from traditional material handling and assembly to warehousing, sorting, and distribution processes. Their role evolved from auxiliary equipment to critical process machinery, and their reach extended from manufacturing sectors like automotive, tobacco, and chemicals to service industries like e-commerce, express delivery, and parking.
The industry’s rapid growth has driven technological progress, yielding constant innovations in methods and models. Integration with new-generation information technologies has enhanced the perceptual and autonomous decision-making capabilities of logistics mobile robot systems, significantly raising their level of intelligence. Concurrently, policy and market-driven capital inflows have spurred the emergence of numerous new enterprises, rapidly expanding the industry’s scale. Data from the Mobile Robot Industry Alliance indicates that from 2012 to 2020, total capital entering the industry via financing exceeded 8 billion RMB. The number of domestic logistics mobile robot manufacturers surged from fewer than 15 to over 220, with an average annual growth rate exceeding 40%. By 2019, nearly all forklift manufacturers had entered this field, and many large enterprises established or expanded specialized equipment companies to meet their internal demand for such automation. The scale of China’s logistics mobile robot industry grew from less than 500 million RMB annually to 7.68 billion RMB in 2020, maintaining an average annual growth rate of over 40% and continuing to show strong momentum. In 2020, 24 companies reported annual production scales exceeding 100 million RMB.
From a strategic perspective, companies are broadly divided into two camps. The first is industry-focused, developing customized products and services based on the specific processes and equipment needs of different user sectors, essentially offering a “you ask, we build” model. This approach excels in manufacturing production processes but has limited potential for massive scalability. The second is product-focused, innovating based on new process models and product concepts promoted to users, offering standardized products and services in a “we build, you adopt” model. This strategy is particularly prominent in warehouse logistics applications and is more conducive to large-scale development.
While the industry’s rapid development is encouraging, it has also highlighted issues that cannot be ignored, spanning marketing, product standards, and service networks. To address these, the Alliance proposed establishing a standard system in 2019. By the end of 2020, it released six universal group standards for “Industrial Application Mobile Robots,” drafted with participation from over 60 enterprises. The goal is to strengthen corporate self-regulation, promote healthy and sustainable industry development, and build consensus on strengthening product standardization, clarifying product positioning, helping users define their needs, and enhancing self-protection. The implementation of these standards is expected to accelerate the industry’s transition from mere existence to excellence, achieving high-quality development. Furthermore, fostering a mindset of coexistence, symbiosis, and mutual benefit among enterprises is crucial, encouraging not only project collaboration and compatibility but also the rapid establishment of a comprehensive service network to collectively maintain the industry market.
The three-step “Manufacturing Power” strategy extends to 2045. In the coming decade, the demand for transformation and upgrading in traditional industries will remain robust, presenting a favorable period for mobile robot industry growth. Industry consolidation and supply chain specialization are likely future trends. Driven by national policies promoting integration between advanced manufacturing and modern services, business models combining product manufacturing and equipment operation will become more prevalent. Companies specializing in marketing and product services will increase. Technologically, “cloud-based” dispatch systems leveraging 5G technology will gain user acceptance, and system features supporting remote operation and maintenance and predictive maintenance will attract significant attention.
2. Classification of Core Components for Logistics Mobile Robots
A logistics mobile robot system consists of stationary and mobile parts. The stationary part, or the ground system, includes the central dispatch system, navigation system, charging system, and communication system. The mobile part is the robot unit itself, comprising the chassis, drive unit, navigation device, communication device, on-board control system, safety protection device, and actuators, as illustrated in Figure 1.
The central dispatch system optimizes task sequencing, dynamically allocates vehicles, and plans paths for multiple mobile robots based on business processes, employing varied scheduling strategies for different applications. The ground navigation system provides positioning signals; depending on the navigation method, corresponding navigation markers are placed on the floor or surroundings, which the robot identifies for active navigation and positioning (less common passive systems directly determine the unit’s pose). The power supply system provides or replenishes power, configured based on the unit’s specific power needs. The communication system facilitates information exchange between the central dispatch system and the mobile robots, and between the dispatch system and other peripheral systems and devices, using various transmission methods (wired, wireless, infrared, power-line carrier, etc.).
The mobile robot chassis, or mechanical body, is the foundational structure, designed and manufactured based on the weight and dimensions of the load. The drive unit encompasses all mechanical components enabling robot movement and steering, including major transmission parts like motors, gearboxes, and drive wheels, along with servo controllers and associated sensors. The navigation device is the sensor that acquires navigation and positioning signals, varying with the navigation method. The on-board control system includes the hardware and software controlling manual or automatic travel, primarily responsible for navigation calculation, path tracking, and motion control. The power unit comprises the power source and ancillary equipment, typically referring to batteries (lead-acid, nickel-metal hydride, nickel-cadmium, lithium-ion, etc.) and on-board charging connection devices, with alternatives like supercapacitors or inductive (non-contact) power supply for special applications. Safety protection devices are critical for active safety, including both contact and non-contact types.
Based on this system composition, the core components (hardware and software) of logistics mobile robots mainly include:
- Mechanical Class: Mechanical body (chassis), drive assemblies, actuators.
- Electrical Class: Batteries, non-contact power supply (CPS) kits, charging equipment, wireless communication devices, on-board controllers, servo drives, laser radar, satellite positioning modules, inertial navigation modules, RFID readers, QR code readers, magnetic/electromagnetic sensors.
- Software Class: Central dispatch software, system monitoring software, on-board control software, planning tools, configuration tools.
3. Market Development of Domestic Core Components for Logistics Mobile Robots in China
Long-term industry development must be rooted in independent innovation. Freeing itself from dependence on foreign technology and products is an essential path for the healthy and steady growth of China’s logistics mobile robot industry. Over the past five years, especially since the escalation of the US-China trade tensions, the rapid development of the domestic logistics mobile robot industry has gradually formed an industrial ecosystem, including core components. The specialized supply chain market has continuously improved and grown, with domestically produced components based on proprietary technology now basically covering all aspects of complete machine manufacturing.
3.1 Development Stages and Characteristics
Domestic logistics mobile robots with proprietary technology initially followed a technical path similar to those in Europe and America. In the 1990s, independent R&D and application began, first mastering control software and a limited number of specialized sensors for tape or electromagnetic navigation, along with directly adoptable domestic batteries and chargers. Limited by annual output at the time, many hardware components were not productized and were often presented to users as rudimentary PCB boards. Key components, including on-board controllers, laser radar, drive assemblies, and servo controllers, still relied on imports, keeping overall machine costs high.
Around 2003, with the booming domestic automotive industry, simplified mobile robots based on Japanese technical concepts emerged in the Chinese market. Their straightforward application model better suited raw material delivery in automotive assembly lines. Advantages like low cost, ease of deployment, and operation led to quick adoption by domestic automotive plants, giving the logistics mobile robot industry scale. Corresponding core components, such as differential drive bogies (including servo controllers), magnetic tape navigation sensors, and microcontroller-based on-board controllers, developed, forming a small-scale market.
Post-2012, the e-commerce boom’s demand for logistics timeliness and the global trend towards Industry 4.0, supported by national policy guidance, transformed logistics mobile robots from a niche product into a darling of “smart manufacturing.” Driven by capital, numerous new companies emerged. According to 2020 Alliance data, among over 250 core component enterprises, 27 were involved in laser radar, 35 in drive components, motors, and servo controllers, 7 in communication products, over 50 in batteries, and over 20 in charging equipment. A specialized supply chain market gradually took shape.
After 2015, traditional forklift companies, sensing market shifts, entered the logistics mobile robot field through system integration or independent R&D. These companies could not only provide complete machines but also customize professional forklift chassis (mechanical bodies) for other manufacturers. By reasonably configuring industrial vehicle technologies like servo drives, wheel arrangements, and hydraulic lifting into their products, they changed the landscape of modified forklifts, reducing waste and significantly lowering design and manufacturing costs for mobile robot companies. Aligning with this shift, some forklift component suppliers recognized the opportunity, designing and manufacturing various specialized drive assemblies, breaking the long-term reliance on imports (from Germany, Italy, etc.). Coupled with the promotion of low-voltage AC motors in the forklift industry and advances in servo control technology, the price of similar domestic products fell to less than half that of imported ones.
3.2 Technological Progress Through Key Components
Within the mobile robot system, the central dispatch and on-board control system software best embody core technological capabilities. As application models diversify, dispatch system application strategies continue to improve, with practical cases spanning process-oriented, cycle-time-based, and discrete industries, as well as serial, parallel, and hybrid systems. With the deepening advancement of smart manufacturing across sectors, dispatch systems have evolved beyond traditional task management, vehicle allocation, and traffic control. They now incorporate more functions to foster the integration of “smart production” and “smart logistics.” Consequently, mobile robot companies typically conduct in-depth research on target industries to build dispatch systems tailored to specific process characteristics, creating technological barriers and core competitiveness. This specialization means that even leading foreign companies cannot offer a one-size-fits-all dispatch system. In recent years, with continuous hardware advancements, the control level of on-board systems has risen significantly. Progress spans from reflectorless laser navigation to visual navigation, high-level access to multi-layer stacking, automatic obstacle avoidance to automatic loading/unloading, continuously elevating intelligence levels, with some technologies surpassing foreign counterparts. Domestically, technology-centric companies have emerged, focusing on providing core technologies (central dispatch software, on-board control hardware/software) while treating complete machine business as supplementary.
Among electrical components, the most remarkable advancements are in laser radar and BeiDou satellite navigation technology. Before 2002, applied laser navigation was based on angle measurement without Time-of-Flight (TOF) ranging. Despite mastering optical principles and angle-measurement positioning algorithms, no domestic company could produce laser radar, as neither laser diodes, gallium arsenide sensors, nor high-precision code wheels met requirements. Today, domestic laser radar product lines are rich, offering single-line and multi-line types. Products not only meet non-contact safety protection needs but also reflector-based laser navigation requirements, with angle resolution and ranging accuracy reaching levels comparable to foreign products, completely breaking the foreign monopoly. Some companies have even developed integrated laser navigation and positioning algorithms based on their product characteristics, reducing development complexity for complete machine manufacturers. Another notable advancement is BeiDou satellite navigation. In 2015, relying solely on China’s BeiDou satellite system and ground differential stations, a 12-meter long, 2.5-meter wide outdoor heavy-duty AGV was observed achieving a repeat positioning accuracy of less than 5 cm while carrying 120 tons, with an operational coverage of up to 10 km. Currently, at least four domestic companies can provide similar BeiDou satellite ground navigation systems and hardware products. Two decades ago, an imported single-axis piezoelectric crystal gyroscope for navigation cost more than a controller. Today, inertial measurement units (IMUs) can be fully integrated into controllers, with the entire controller priced at about one-third of the former imported gyroscope cost.
In communication technology, progress has been from 4800 bps RF communication to 100 Mbps WiFi, and now to 5G communication, vastly improving data volume and real-time performance. Concerns like AP handover, wireless roaming, and communication loss, once troubling non-specialists, have diminished. For complex project implementation, professional communication companies provide support, significantly reducing system deployment difficulty.
Beyond these key components, other supporting devices have also made substantial technological strides. For instance, UWB wireless positioning technology can address traffic safety in human-robot mixed environments; non-contact charging technology solves charging issues in clean rooms; the load-bearing and traction capacity of drive assemblies continue to increase; and battery energy density ratios keep improving. Hardware technology upgrades and cost reductions further expand product application ranges.
Overall, the domestic core component market is gradually maturing, with core technologies becoming self-sufficient, product quality continuously improving, and sales prices stabilizing or declining, fundamentally driving the rapid development of China’s logistics mobile robot industry.
4. Industry Perspective on Technology Trends for Core Components
At its current stage of development, many core component companies are no longer traditional suppliers in the conventional sense. Their technological capabilities are extending downstream, making them more akin to technical supporters for complete machine manufacturers. Drive assembly companies can guide design selection based on mobile robot load capacity, with running speed and steering angle independently managed by servo controllers, offering precision and response times superior to closed-loop control from the on-board controller. Navigation product companies, leveraging their product features, develop navigation and positioning algorithms, providing pose information directly to the on-board control system, eliminating the need for complex calculations by the controller and reducing system complexity. These trends indicate that, similar to the automotive and forklift industries, the future mobile robot industry will not only involve simple industrial segmentation but will progress towards “letting specialized companies handle specialized tasks.” Complete machine manufacturers may resemble assembly plants, no longer needing to master all technologies, which could significantly lower the technical threshold for production. Simultaneously, this presents new challenges for traditional mobile robot enterprises.
It is believed that as the industry scale continues to expand, logistics mobile robots will inevitably rely on standardized, configurable products to meet a customized market. Therefore, hardware interfaces for core components will become more standardized, control software more configurable, data transmission and expression at the business layer more unified, and core technologies more specialized. These changes could pool resources from various parties, reduce R&D risks, enhance product quality, lower production costs, and strengthen market responsiveness. However, they also risk intensifying product homogenization, increasing market competition, and further compressing profit margins.
In summary, the prospects are promising, but the path remains challenging. Recommendations are as follows: The development of China’s logistics mobile robot industry requires more professionals; cultivating technical and skilled talent should be a long-term plan for universities and enterprises. All companies should emphasize the implementation of standards, which are crucial for controlling product quality and cost and will serve as a “measuring stick” for users. High priority must be given to product operational safety and reliability to collectively safeguard industry reputation. Establishing a comprehensive after-sales service system, akin to the automotive 4S shop model for localized service, should be expedited. System intelligence levels require continuous enhancement. Product technologies for unconventional environments (where human activity is restricted, such as explosive atmospheres, radiation, extreme temperatures) need further development.
