This August, Hunan Province introduced new guidelines aimed at accelerating the development of the intelligent robotics industry, designating Changsha as the focal point for advancing robot bodies, high-end controllers, and embodied intelligence algorithms. This new direction poses a critical question: what kind of environment does a city need to provide so that artificial intelligence can truly "grow a body," transitioning from a technology to a full-fledged industry, and moving from labs and showrooms into the real world? Shenzhen provides a compelling case study.

In 2025, Shenzhen's robotics industry reached a total output value of 242.6 billion yuan, a year-on-year increase of 20.56%. Components, complete machines, large-scale manufacturing, and application scenarios have rapidly converged there. Seeking insights for Changsha's own development, a reporter traveled to Shenzhen, exploring the upstream supply chain, visiting robot manufacturers, and observing robots in action in parks and shopping districts. The conclusion is clear: the race is no longer about isolated technological breakthroughs; it's a competition of entire industrial ecosystems. No single company can dominate; the optimal path is a thriving, interconnected ecosystem where diverse companies leverage their strengths, and technology, manufacturing, and applications form a symbiotic whole.

Exploring Shenzhen's Dense Industrial Chain

To grasp the depth and density of Shenzhen's embodied intelligence chain, one can start by examining a single robot and tracing all the companies, technologies, and processes behind it. The first stop was to look at a robot's "hand." At the DaiMeng Robot showroom, the reporter donned a data collection device, bending fingers to pick up an eraser. This simple human action was broken down into a stream of data points: pressure, shear force, torque, and slippage. Robots need to learn this kind of "feel" through data—a camera can show a cup, but not that it's slippery; a robotic hand can reach out, but must learn the right amount of force. DaiMeng focuses on this niche but critical area, developing sensors and end-effectors with touch sensitivity and using the collected data for model training.

From this single vantage point, the depth of the entire chain becomes apparent: vision, touch, joints, dexterous hands, algorithms, models, and body control. A robot is a complex system built from countless specialized parts. Some focus on perception, others on execution or control. This specialization has created a highly dense collaborative network across Shenzhen. The "Robot Valley" on Liuxian Avenue is a prime example, where a 15-kilometer integrated supply chain enables a remarkable workflow: "design in the morning, prototype by afternoon, mass-produce the next day, and ship globally within a week." The industry's vitality flows from the links between these specialized segments.

Within this chain, complete robot manufacturers play a unique connecting role, linking upstream component expertise with downstream real-world applications. A visit to UBTech demonstrated this. The reporter watched a Walker S2 robot complete a material handling task and then walk to a charging station, where it autonomously swapped its own battery, a process taking about three minutes. Though less flashy than dancing, this action addresses the industry's core concerns: minimizing downtime, keeping pace with production, and ensuring stable long-term operation. Factories won't order based solely on a slick demo video. The journey from a robot that "moves" to one that "works" is fraught with challenges related to reliability, precision, cost, and efficiency.

Integrators bridge the gap between upstream tech and industrial needs. They define what a robot's vision, joints, and energy management must be through specific tasks, and then feed requirements from the production line back to their suppliers. UBTech noted that when they relocated to Nanshan in 2015, the surrounding robotics ecosystem was sparse. Over the last decade, as university resources, the electronics industry, and the Greater Bay Area's manufacturing systems converged, the entire ecosystem benefited. A breakthrough by one company can become a product for another, and a new demand from an integrator can birth a new niche. Shenzhen's density isn't just about having many companies; it's about creating an interlocking system where specialization translates into powerful collaboration.

The Manufacturing Might Fueling a "New" Industry

Embodied intelligence is a future industry, but it wasn't born in a vacuum. It relies on decades of manufacturing expertise. Shenzhen's robotics rise is built on its history: electronics provided components and engineers, consumer electronics honed precision manufacturing and rapid delivery, new energy vehicles contributed electric motors and sensors, and AI supplied the "brains." Lingyi iTech is a prime example. Similar to Changsha's Lens Technology, it's a leader in precision manufacturing for consumer electronics. The company migrated from making structural components for phones to electric vehicles, and now to robotics. The product changed, but the underlying capabilities—precision machining, molding, production line design, quality control—remained and were repurposed. This explains why Shenzhen's robotics sector grew so quickly: the unseen foundations were already in place.

Moving Robots from Showrooms to Real-World Scenes

Shenzhen's Qianhai Park features a "Smart Cube" that has brought robots out of the lab and into daily life. Customers order coffee or ice cream via QR code, and a robot makes it. This simple transaction is a complete delivery test, demanding reliable perception, planning, and operation. While a showroom demo can be pre-programmed, a real commercial order is a series of unscripted demands. The company behind this, ZhiPingFang, sees this not just as a service but as a business model and training ground. Each operation provides data to refine models and improve the product. This same technology is also deployed in factories, where it tackles demanding tasks like PCB loading and unloading on production lines at HKC.

Building an Ecosystem from Dispersed Strengths

Shenzhen's advantage lies not just in its individual strengths—companies, manufacturing, scenarios, research—but in its ability to connect them into a self-sustaining ecosystem. The key is "connection." The city facilitates this by providing public service platforms, as outlined in its 2025 action plan, which includes testing grounds, innovation centers, and open-source communities. "Training coupons" support companies using intelligent computing power. These infrastructure pieces solve shared problems that no single company could handle alone. Simultaneously, the city opens up real-world scenarios. Nanshan District’s "揭榜挂帅" project lets scenario owners (like government or hospitals) present needs, while the "百景入链" initiative connects companies with commercial districts. Scenarios become a key part of the innovation loop: real-world problems drive R&D, and product feedback leads to the next round of improvements. Plans for 2026-2028 further aim to deploy humanoid robots in over 10 real-world scenarios across industrial, service, and special environments. From platforms to data and computing, these are pieces of a larger "network" that gives R&D a purpose, manufacturing a foundation, and products a market, turning one company's problem into another's opportunity.

Charting Changsha's Path from Having to Excelling

Shenzhen's ecosystem grew from decades of accumulation in electronics and manufacturing; Changsha cannot—and need not—duplicate that exact journey. Changsha has its own strengths: a rich industrial base in engineering machinery, automotive manufacturing, and advanced computing. Companies like Sany, Zoomlion, Sunward, and Lens Technology possess deep expertise in equipment manufacturing and precision structures. Universities like NUDT, Central South University, and Hunan University contribute strong research in vision and control algorithms, supported by the National Supercomputing Center in Changsha. These assets, combined with diverse application scenes in mining and emergency rescue, are significant advantages. As Li Jinbo, Chairman of WanWei Robot, notes, these industrial and research foundations form a unique local advantage. However, having the assets is not the same as having an ecosystem. Some companies point to a lack of industrial agglomeration and specialized talent as current bottlenecks. The challenge is to create the connections that allow these resources to coalesce.

The lesson from Shenzhen is not to copy its physical layout but to emulate its logic: let leading companies act as anchors, facilitate collaboration across the value chain, and ensure technology moves quickly into production. By weaving its existing strengths in manufacturing, research, and computing into a new, interconnected fabric, Changsha can create a vibrant ecosystem where innovation isn't just created but can thrive and grow.

Editor's Note: The Roots Matter More Than the Fruits

Visiting Shenzhen leaves a lasting impression, but it's not the impressive robots that linger in the mind—it's the intricate, hidden root system that makes them possible. A robot is the "fruit," but it relies on a subterranean network of components, algorithms, talent, and scenarios for its nutrients. This system isn't built overnight. It's the product of decades of accumulated capability, linking past successes like consumer electronics to future ones like embodied intelligence. A flourishing forest isn't just many trees; it's an interconnected web of roots and symbiotic relationships. Cultivating these roots requires both market evolution and smart government policy. An ecosystem that necessitates patience and support is more valuable than importing any single high-profile company. While a factory can be built quickly, an industrial ecosystem takes time to grow. For Changsha, which already has strong foundations in engineering and a rich research landscape, the true challenge lies in fostering these connections and letting its investments develop deep, strong roots that will sustain the industries of tomorrow. The world sees the fruit; it's the roots that determine long-term vitality.
