The rapid evolution of intelligent manufacturing is fundamentally transforming global industries, driven by the integration of advanced technologies such as artificial intelligence, robotics, and the Internet of Things. Embodied intelligence, which emphasizes the coupling of perception, decision-making, and action in physical systems, is emerging as a pivotal force in this transformation. By enabling machines to interact adaptively with their environments, embodied intelligence enhances the flexibility, autonomy, and efficiency of manufacturing processes. This article explores the application and development of embodied intelligence in intelligent manufacturing, focusing on its technological evolution, key components, and practical implications. Through a detailed analysis of multi-modal data fusion, foundation models, force control, and motion planning, we construct a comprehensive technical framework for embodied intelligence-driven systems. Additionally, we examine the challenges and future trends, providing insights to guide further research and implementation in this dynamic field.
The progression of intelligent manufacturing can be divided into three distinct stages: rule-based automated manufacturing, data-driven digital intelligent manufacturing, and embodied intelligence-enabled intelligent manufacturing. Each stage represents a leap in technological sophistication and operational capability. The transition from rigid automation to adaptive, intelligent systems underscores the growing importance of embodied intelligence in addressing complex manufacturing demands. As industries strive for higher levels of autonomy and resilience, the role of embodied robots becomes increasingly critical in achieving these goals.

The embodied intelligence-driven intelligent manufacturing interaction model revolves around the continuous loop of perception, decision-making, execution, and feedback. This model integrates humans, machines, and the environment into a cohesive system where embodied robots act as central agents. Humans provide high-level guidance and supervision, while embodied robots leverage multi-modal sensors to perceive environmental data, analyze it through cognitive modules, and generate actionable decisions. The execution phase involves precise control of machinery, with real-time feedback enabling iterative improvements. This closed-loop interaction enhances the system’s adaptability to dynamic production scenarios, ensuring robust performance in unstructured environments.
Key technical elements of embodied intelligence in manufacturing include multi-modal data fusion perception, foundation model-based systems, force control, and robotic motion planning algorithms. Multi-modal data fusion combines inputs from various sensors, such as vision, audio, and tactile sensors, to create a comprehensive understanding of the manufacturing environment. The fusion process can be categorized into data-level fusion (early fusion), feature-level fusion (deep fusion), and decision-level fusion (late fusion), each suited to different scenarios. For instance, in additive manufacturing, integrating acoustic, thermal, and visual data allows for real-time defect detection and process optimization. The mathematical representation of multi-modal fusion can be expressed as:
$$Y = f(X_1, X_2, \dots, X_n)$$
where \(Y\) is the fused output, \(X_i\) represents data from different modalities, and \(f\) denotes the fusion function, often implemented using deep neural networks.
Foundation models, such as large language models, play a crucial role in enhancing the cognitive capabilities of embodied robots. These models enable semantic understanding of manufacturing tasks, facilitating complex decision-making and autonomous execution. For example, in assembly operations, embodied robots can interpret natural language instructions and dynamically adjust their actions based on real-time environmental cues. The integration of knowledge graphs and transformer architectures allows for robust reasoning about task dependencies and potential failures. The decision-making process can be modeled as:
$$A^* = \arg\max_A P(A | S, M)$$
where \(A^*\) is the optimal action, \(S\) is the current state, and \(M\) represents the foundation model’s knowledge base.
Force control technology is essential for precise manipulation in embodied robotics, particularly in tasks requiring delicate interactions, such as assembly and打磨. By incorporating force sensors and adaptive control strategies, embodied robots can adjust their movements to accommodate variations in workpiece geometry and material properties. Impedance control and hybrid force-position control are commonly used techniques to achieve compliant interactions. The force control law can be described as:
$$F = K_p (x_d – x) + K_d (\dot{x}_d – \dot{x})$$
where \(F\) is the applied force, \(K_p\) and \(K_d\) are control gains, \(x_d\) and \(x\) are desired and actual positions, and \(\dot{x}_d\) and \(\dot{x}\) are velocity terms. This ensures stable and accurate force application during operations like精密装配.
Robotic motion planning algorithms enable embodied robots to navigate complex environments and perform tasks efficiently. Sampling-based methods, such as Rapidly-exploring Random Trees (RRT), and heuristic approaches, like A* algorithm, are widely used for path planning. Trajectory generation considers kinematic and dynamic constraints to produce smooth and executable motions. The path planning problem can be formulated as:
$$\min_{p} \int_0^T \| \dot{p}(t) \|^2 dt \quad \text{subject to} \quad p(t) \in \mathcal{F}_{\text{free}}$$
where \(p(t)\) is the path, \(T\) is the time horizon, and \(\mathcal{F}_{\text{free}}\) denotes the obstacle-free space. These algorithms are critical for applications like autonomous guided vehicles in warehouses.
The technical framework for embodied intelligence-driven intelligent manufacturing comprises seven layers: physical, data, algorithm, perception, decision, execution, and feedback. The physical layer includes sensors, robots, and computing devices, while the data layer manages multi-modal manufacturing data. The algorithm layer integrates perception, decision, and learning algorithms, such as reinforcement learning and imitation learning. The perception layer processes sensory inputs to understand the environment, and the decision layer employs knowledge graphs and optimization techniques to generate action sequences. The execution layer controls robotic modules and human-robot collaboration, and the feedback layer enables continuous improvement through real-time monitoring and anomaly detection. This hierarchical structure ensures seamless operation and adaptability in smart manufacturing systems.
Embodied intelligence revolutionizes production modes by introducing flexibility and autonomy. In precision manufacturing, embodied robots can adapt to varying part tolerances and environmental conditions, reducing errors and enhancing quality. For instance, in electrolytic aluminum carbon block grinding, embodied robots adjust grinding force and trajectory based on real-time sensor data, significantly improving accuracy. In flexible manufacturing, these systems shorten setup times from weeks to hours, enabling rapid response to market changes. Moreover, embodied robots can operate in hazardous environments, such as喷涂 booths, minimizing human exposure to risks.
In warehousing and logistics, embodied intelligence facilitates automation through autonomous mobile robots and automated guided vehicles. These systems use LiDAR and vision sensors for navigation and task execution, optimizing inventory management and material handling. Force control algorithms ensure safe and efficient load manipulation, while real-time data integration enhances supply chain visibility. The path planning for autonomous vehicles can be optimized using:
$$J = \sum_{t=1}^T \left( \| p_t – p_{\text{goal}} \|^2 + \lambda \cdot \text{collision\_risk}(p_t) \right)$$
where \(J\) is the cost function, \(p_t\) is the position at time \(t\), and \(\lambda\) balances goal achievement and safety.
Predictive maintenance and inspection are another critical application area. Embodied robots equipped with vibration, temperature, and acoustic sensors can monitor equipment health and detect anomalies early. By leveraging machine learning models, these systems predict failures and schedule maintenance proactively, reducing downtime. In high-risk settings like nuclear plants, embodied robots perform inspections without human intervention, enhancing safety and reliability.
Human-robot collaboration is deepened through embodied intelligence, enabling natural interactions and shared task execution. Multi-modal perception allows embodied robots to interpret human gestures and voice commands, adjusting their behavior accordingly. For example, in assembly lines, embodied robots can assist workers by handling repetitive tasks while adapting to human pace. The collaboration efficiency can be modeled as:
$$E_{\text{collab}} = \frac{T_{\text{human}} + T_{\text{robot}} – T_{\text{overlap}}}{T_{\text{total}}}$$
where \(T_{\text{human}}\) and \(T_{\text{robot}}\) are task times, and \(T_{\text{overlap}}\) represents simultaneous work periods.
Despite its potential, embodied intelligence faces several challenges in manufacturing applications. The lack of multi-modal data hampers the training and performance of embodied robots, as high-quality, annotated datasets are scarce. Complex manufacturing environments, with issues like variable lighting and electromagnetic interference, increase the difficulty of perception and understanding. AI hallucinations, where models generate incorrect inferences, pose safety risks, especially in critical processes. Soft-hardware integration problems, such as compatibility issues and real-time control limitations, impede the full realization of intelligent capabilities. Additionally, ethical and legal gaps, including accountability and standardization, create compliance challenges.

Future trends indicate that embodied intelligence will continue to expand into diverse manufacturing scenarios, from traditional sectors to emerging fields like aerospace and healthcare. Human-robot collaboration will become more intuitive, with embodied robots acting as proactive partners rather than passive tools. The industry ecosystem will mature, fostering collaboration among enterprises, research institutions, and governments to drive innovation and standardization. As technology advances, embodied robots will play a central role in achieving sustainable and resilient manufacturing systems.
To accelerate the development of embodied intelligence-driven intelligent manufacturing, several recommendations are proposed.

Third, establish safety standards and regulatory frameworks to ensure reliable and ethical deployment of embodied robots. Fourth, expand application scenarios through pilot projects and cross-industry collaborations to unlock new market opportunities. By addressing these areas, embodied intelligence can fully realize its potential in transforming manufacturing.
In conclusion, embodied intelligence represents a paradigm shift in intelligent manufacturing, enabling systems to perceive, reason, and act with unprecedented autonomy. Through advancements in multi-modal data fusion, foundation models, and robotic control, embodied robots are enhancing production efficiency, flexibility, and safety. However, overcoming challenges related to data scarcity, environmental complexity, and ethical concerns is essential for widespread adoption. By fostering innovation and collaboration, the manufacturing sector can harness the power of embodied intelligence to build smarter, more adaptive production environments for the future.
