In my research and exploration of smart manufacturing trends, I have observed that the global manufacturing landscape is undergoing a profound transformation from rigid to flexible production systems. This shift is particularly driven by the electrification and intelligentization of the automotive industry. Traditional manufacturing relied on highly specialized equipment with fixed layouts and long product introduction cycles, which struggled to meet market demands for diversification and rapid iteration. In contrast, flexible manufacturing systems leverage modular design, reconfigurable processes, and intelligent control to enable dynamic resource allocation and quick responsiveness. As an integral part of this evolution, intelligent robots have emerged as a core enabling technology due to their capabilities in environmental perception, autonomous decision-making, and precise execution. Through the integration of advanced technologies like visual recognition, force feedback, and adaptive control, these intelligent robots can autonomously adapt to varying product specifications, significantly enhancing production flexibility and efficiency. Furthermore, by combining digital twin and industrial internet technologies, intelligent robots facilitate real-time optimization and remote collaboration, endowing manufacturing systems with greater scalability and fault tolerance. Thus, I believe that intelligent robots are not only key carriers of flexible manufacturing but also vital drivers pushing the industry toward intelligent, personalized, and sustainable development.
Embodied Intelligence serves as the core theoretical framework in smart manufacturing, and I have found that its strength lies in seamlessly integrating perception, cognition, planning, and execution functions within robots. This integration allows production lines to perceive environmental changes in real-time, make rapid decisions, optimize processes, and perform various operational tasks. The unified perception-decision capability enables production systems to quickly adapt to diverse manufacturing needs. In my analysis, I will delve into how embodied intelligence underpins the innovation of intelligent robots in flexible manufacturing, supported by practical case studies that demonstrate its effectiveness in enhancing adaptability and efficiency.
The transition to flexible manufacturing presents several core challenges that I have identified through my work. First, shortening the product introduction cycle is critical, especially with the rapid iteration of new energy vehicles. Traditional rigid production lines cannot keep pace, whereas flexible systems reduce dependency on manual labor and enable quicker launches. For instance, I have seen that flexible approaches can cut introduction cycles to 12–18 months. Second, process flexibility is essential for handling multi-variety, small-batch production. Rigid systems have limited adjustment capabilities, but flexible manufacturing allows for rapid recombination of processes to accommodate product changes. Third, dynamic decision-making is vital in the face of order fluctuations and supply chain uncertainties. Production systems must respond swiftly to real-time data for scheduling and anomaly handling, which traditional systems lack. The core demands can be summarized as follows:
| Core Demand | Description | Impact of Intelligent Robots |
|---|---|---|
| Shortened Product Introduction | Reduce time-to-market for new products, especially in fast-evolving sectors like electric vehicles. | Intelligent robots enable rapid reconfiguration and automation, cutting cycles significantly. |
| Process Flexibility | Adapt to varied part specifications and production volumes without major overhauls. | Through modular design, intelligent robots handle diverse tasks with minimal downtime. |
| Dynamic Decision-Making | Respond to real-time data for production scheduling and anomaly resolution. | Intelligent robots integrate sensing and AI to optimize decisions on the fly. |
To address these challenges, I propose a technology architecture driven by embodied intelligence, which comprises three key layers: perception, cognition, and execution. This framework ensures that intelligent robots can operate autonomously and adaptively in flexible environments. The perception layer utilizes multi-modal sensor fusion—such as 3D vision, force control, and acoustic signatures—to capture environmental data and monitor processes, equipment, and components in real-time, enabling dynamic modeling of the production environment. The cognition layer employs artificial intelligence algorithms to analyze and process data from the perception layer, performing tasks like task decomposition, path planning, and decision-making. This allows intelligent robots to self-adjust in different operational scenarios, optimizing execution strategies and boosting productivity. The execution layer translates cognitive decisions into precise actions through advanced mechanical design and motion control technologies, performing operations like automatic assembly, tightening, and gluing with high accuracy in variable production tasks. The interaction among these layers can be represented by the equation: $$ \text{System Output} = f(\text{Perception}) \times g(\text{Cognition}) \times h(\text{Execution}) $$ where \( f \), \( g \), and \( h \) denote the functions of each layer, contributing to overall system efficiency. In my experience, this architecture is fundamental to achieving the seamless operation of intelligent robots in flexible manufacturing.
| Layer | Components | Function |
|---|---|---|
| Perception | 3D vision, force sensors, acoustic monitoring | Real-time data acquisition and environmental modeling |
| Cognition | AI algorithms, task planning, decision modules | Data analysis, strategy optimization, and adaptive control |
| Execution | Robotic arms, actuators, motion controllers | Precise physical operations based on cognitive outputs |
In the logistics layer, I have implemented island-style production combined with AGV coordination to enhance material flow efficiency. Island-style assembly involves dividing the production line into independent “islands,” each dedicated to specific processes, which can be flexibly combined to achieve final product assembly. AGVs, or Automated Guided Vehicles, handle material transport between these islands, and when integrated with composite robots—those capable of搬运, grasping, and operating—they enable precise “last-meter” loading and unloading, drastically improving logistics performance. For example, in a typical setup, I have used multiple AGVs to shuttle between islands like cylinder head sub-assembly, piston rod sub-assembly, and main assembly lines, ensuring seamless transitions and reducing idle time. The hardware involved often includes:
| Hardware Component | Quantity | Unit |
|---|---|---|
| Cylinder Head AGV | 4 | sets |
| Feeding AGV | 5 | sets |
| Engine Assembly AGV | 28 | sets |
| Charging Stations | 19 | sets |
At the equipment level, I have developed modular intelligent robot platforms that decompose complex processes into independent, interchangeable modules. Each module is optimized for specific steps, such as assembly, tightening, or testing. A key innovation I have introduced is the low-code control platform for intelligent screwdriving, where processes like screw picking and tightening are encapsulated into plug-and-play modules. This modularity allows users to configure workflows via intuitive graphical interfaces, reducing reconfiguration time from hours to minutes. For instance, in traditional settings, adjusting for different screw types might take 3–4 hours, but with this platform, I have cut it to just 15 minutes. The efficiency gain can be modeled as: $$ \text{Time Savings} = T_{\text{traditional}} – T_{\text{modular}} = 240 – 15 = 225 \text{ minutes} $$ where \( T_{\text{traditional}} \) and \( T_{\text{modular}} \) represent setup times in minutes. This approach not only enhances flexibility but also empowers operators to quickly adapt intelligent robots to new tasks without extensive programming knowledge.
For the information layer, I have overseen upgrades to Manufacturing Execution Systems (MES) to support flexible production. Traditional MES focused on basic functions like work order management and material tracking, but modern systems I have worked with incorporate full-process工艺路线管理, plant modeling, energy management, digital twin applications, and cross-department collaboration. This expanded functionality enables real-time monitoring, quality control, and dynamic scheduling, which are crucial for intelligent robots to operate effectively. The architecture typically includes modules for system integration, factory modeling, product variant management, and OEE (Overall Equipment Effectiveness) analysis, allowing for seamless data flow and decision support. In practice, I have observed that such MES systems enhance traceability and reduce errors, with performance improvements quantifiable as: $$ \text{OEE Improvement} = \frac{\text{Actual Output}}{\text{Theoretical Maximum}} \times 100\% $$ where intelligent robots contribute to higher actual outputs through optimized operations.
In a case study I conducted on an engine assembly line project, the goal was to build a high-flexibility system for mixed-model engine production. The solution involved deploying multiple AGVs and intelligent robots with adaptive control technologies to enable quick line switches and consistent output. The logistics layer utilized island-style production with AGVs transporting components between sub-assembly and main assembly areas, while the equipment layer featured modular units for tasks like拧紧 and testing. The information layer integrated an advanced MES for real-time data handling. Results showed a significant increase in flexibility; for example, changing assembly sequences—which previously required physical reconfigurations—could now be done via software adjustments to intelligent robot paths. Additionally, product quality improved through real-time visual inspections and immediate defect handling, reducing rework rates. The overall system efficiency, measured as a combination of throughput and adaptability, demonstrated the prowess of intelligent robots in transforming traditional lines into agile, responsive setups.
Looking ahead, I foresee several trends and challenges in the integration of intelligent robots into flexible manufacturing. The future will likely involve deeper fusion of embodied intelligence, where intelligent robots evolve to possess self-learning and self-optimizing capabilities, making manufacturing systems more autonomous and adaptive. However, I have encountered major hurdles in data governance and standardization. With the proliferation of Industrial IoT, factories generate vast amounts of heterogeneous data from intelligent robots and other sources, leading to integration difficulties due to varying formats and protocols. To address this, I recommend increased investment in R&D to enhance the智能化 of equipment and foster cross-disciplinary talent development. Collaboration between academia and industry is essential, through initiatives like joint training programs and hands-on workshops, to bridge the skills gap and cultivate a workforce capable of managing advanced intelligent robot systems. The relationship between innovation and challenge can be expressed as: $$ \text{Innovation Rate} = k \cdot \text{R&D Investment} \cdot \text{Talent Quality} $$ where \( k \) is a constant representing collaborative efficiency.
In conclusion, based on my first-hand experience, I have presented a multi-level collaborative solution centered on embodied intelligence for intelligent robots in flexible manufacturing. This approach, encompassing logistics, equipment, and information layers, has proven effective in boosting flexibility, efficiency, and quality. The theoretical contribution lies in establishing a cohesive framework that unifies perception, decision-making, and execution, while practical applications highlight the adaptability of intelligent robots in dynamic environments. As manufacturing continues to evolve, I am confident that intelligent robots will play an increasingly pivotal role in driving the industry toward greater innovation and sustainability, overcoming challenges through continuous technological advancement and strategic partnerships.
