SIASUN Robot & Automation Co., Ltd. (Shenzhen Stock Exchange ticker 300024) is one of China's largest robotics manufacturers and a publicly listed company on the Shenzhen Stock Exchange's ChiNext board. Founded on April 30, 2000 by Qu Daokui as a commercial spin-off from the Shenyang Institute of Automation (SIA) under the Chinese Academy of Sciences (CAS), SIASUN develops and manufactures industrial robots, collaborative robots (cobots), automated guided vehicles (AGVs), autonomous mobile robots (AMRs), vacuum cleanroom robots for semiconductor production, special robots for military and aerospace use, and bipedal humanoid robots. The company reported revenue of CNY 4.12 billion for the full year 2025, broadly flat against the CNY 4.14 billion recorded in 2024, serves over 4,000 international enterprises in more than 40 countries, and has completed over 18,000 project deployments since its founding.[1][2][3][4][38]
The company name SIASUN is a transliteration that combines SIA (Shenyang Institute of Automation) with SUN, and is rendered in Chinese as 新松 (Xinsong, literally "new pine"). SIASUN holds a unique position in the global robotics market as the first Chinese robotics company to go public, the country's largest robotic industrial base operator, and a designated national champion under Beijing's high-end manufacturing programs. Its product portfolio spans the full spectrum of industrial and service robotics, from articulated and SCARA robot arms to the DUCO collaborative robot brand, mobile logistics platforms, vacuum manipulators for semiconductor fabs, defense-grade heavy-load transporters, and the Songxing bipedal humanoid robot unveiled in 2025.[1][5][6]
SIASUN sits at the intersection of Chinese state research, industrial policy, and capital markets. Its largest shareholder is the Shenyang Institute of Automation of the Chinese Academy of Sciences, the institution credited with developing China's first industrial robot prototype in the early 1980s. This origin places SIASUN within a small group of CAS-spawned enterprises whose stated mission is to translate state-funded research into commercial scale. The company describes itself as a "high-tech listed enterprise specializing in robotic technology and intelligent manufacturing" and claims to have written more than 100 industry-first achievements in Chinese robot development.[1][7]
The corporate motto "Robots make a better world" and the four-part vision of "Chinese Speed, Chinese Level, Industry-leading, World-class" reflect both a domestic-champion identity and an export ambition. SIASUN's products and services target two thirds large-enterprise customers, with partnerships across many Fortune Global 500 companies. The firm consolidates manufacturing, research, and integration capabilities at a 340,000-square-foot industrial base in Shenyang that opened in 2017 and integrates production with finance, education, and innovation under what Qu Daokui called "a new ecological platform."[1][8]
SIASUN's lineage begins with the Shenyang Institute of Automation (SIA), founded in November 1958 under the Chinese Academy of Sciences. After several reorganizations during the 1960s and early 1970s, the institute was formally designated the Shenyang Institute of Automation, Chinese Academy of Sciences, in August 1972. SIA became a pioneer in Chinese robotics during the 1980s. In June 1982, the institute developed China's first industrial robot prototype, the SZJ-1 teaching-playback manipulator. In 1984, the National Robot Demonstration Project was officially launched based at SIA, establishing the institute as the cradle of China's robotics technology with more than 20 documented firsts in domestic robot development.[5][9]
Qu Daokui joined SIA in 1992 as a young researcher. According to widely cited accounts, a visit that year to a Volkswagen plant in Wolfsburg, Germany, where hundreds of robots were running a car assembly line, motivated Qu to pursue applied robotics. He observed that few Chinese laboratories had robots for research use while foreign factories had already industrialized them at scale. The contrast informed his decision, eight years later, to lead a team of SIA researchers in founding a commercial spin-off that could carry the institute's research into the market.[7][10]
SIASUN Robot & Automation Co., Ltd. was incorporated on April 30, 2000, with headquarters in the Hunnan high-tech district of Shenyang, Liaoning. The founding team set out to commercialize SIA's existing robotics research portfolio, drawing on national high-technology research and development programs such as the 863 Program to bridge laboratory innovation with industrial deployment. Early product priorities included industrial robot arms for automotive welding and material handling, mobile robots for intralogistics, and special-purpose platforms for cleanroom and vacuum environments.[10][11]
During its first decade, SIASUN built up engineering, production, and integration capabilities, recruiting from CAS and from regional engineering universities. Government procurement, especially in automotive and defense applications, anchored early revenue. The Chinese 863 Program and successor national plans channeled research grants and demonstration project funding to the company, helping it scale its product portfolio beyond the narrow output of a research institute.[6][10]
SIASUN listed on the Shenzhen Stock Exchange's ChiNext board for growth enterprises on October 30, 2009. The company priced its initial public offering at CNY 39.80 per share for an issuance of 15.50 million shares, becoming the first Chinese robotics company to float shares publicly. The IPO provided expansion capital and gave the company a continuous source of equity for follow-on capacity investments. The listing also turned SIASUN into a benchmark name in domestic equity coverage of the robotics theme and a frequent index constituent for Chinese automation and high-end manufacturing baskets.[6][12] Read more about industrial robot market structures and listing comparisons.
In December 2014, SIASUN signed a new special-robot order contract with a total contract value of CNY 169.2 million. The agreement broadened the company's serial production of special equipment and reinforced its position as a supplier of defense-related robotic systems, particularly heavy-load mobile platforms and cleanroom transport units used in aerospace, smelting, and large-scale logistics.[3]
In October 2017, SIASUN opened a CNY 2 billion (USD 302 to 303 million) robotic industrial base in Shenyang, then the largest dedicated robotics facility in China. The campus covered 340,000 square feet and required five years to build. It contained a headquarters office building, a robotics exhibition and demonstration center, a research and development center, and multiple manufacturing centers covering digital equipment and large machinery. Annual production capacity at the base exceeds 10,000 robot sets, and the site hosts what Chinese state media described as the country's first demonstration manufacturing project for Industry 4.0. The factory integrates robots, intelligent equipment, and information technology across product design, production, quality, and logistics processes.[8][13]
Also in 2017, SIASUN became the first China-based member of the Robotic Industries Association (RIA), the United States-based trade group later folded into the Association for Advancing Automation (A3). The membership was an early signal of SIASUN's ambition to engage international standards bodies and trade groups, ahead of the broader Chinese push into export-facing markets in subsequent years.[3]
In 2019, SIASUN began construction of a manufacturing facility in Thailand's Eastern Economic Corridor (EEC) to support local automotive and electronics production. The site grew into a regional production hub for Southeast Asia and was later cited by SIASUN and Thai officials as the area's first 5G smart factory deployment. Company leadership announced plans for additional research and development centers in Europe, North America, and Japan, with the goal of localizing engineering for each major customer region.[3][14]
During the COVID-19 pandemic in early 2020, SIASUN donated 21 robots and 10 electric adjustable beds to hospitals in Shenyang, with seven of the robots routed through the local Red Cross. The donated robots were used in disinfection, material transport, and other tasks that reduced human contact in clinical settings. The episode contributed to the broader visibility of Chinese robotics suppliers in healthcare contingency response.[3]
In 2024, founder Qu Daokui retired from his executive role at SIASUN, ending more than two decades of day-to-day leadership. By that year Qu was 63 years old and had concurrently held a series of national robotics policy roles, including deputy director of the National Engineering Research Center of Robotics, head of the National Robotics Standardization General Working Group of China, chair of the China Robot Industry Innovation Alliance, and president of the China Robot Industry Alliance. SIASUN continued to be classed as a CAS-affiliated enterprise after the transition.[15]
At the 2025 World Robot Conference in Beijing, held from August 8 to 12 at the Beiren Yi Chuang International Convention and Exhibition Center, SIASUN unveiled the Songxing bipedal humanoid robot together with a humanoid product family that included the Songyi wheeled humanoid, the RICO wheeled humanoid for material handling, an intelligent humanoid dual-arm platform, and the Duoke coffee service robot. The Songxing launch positioned SIASUN as one of the established industrial robot incumbents entering the bipedal humanoid category at scale.[16][17]
The 2025 to 2026 period saw SIASUN press deeper into embodied intelligence, post a record robot shipment year alongside a wider net loss, and achieve a closely watched breakthrough in automotive welding.
On April 30, 2025, the twenty-fifth anniversary of its founding, SIASUN established the SIASUN Embodied Intelligence Research Institute in Shenyang. The institute was set up to concentrate the company's work on AI large language models, multimodal perception, and autonomous decision-making, and to act as an incubator linking forward-looking research to production and deployment of humanoid and service robots.[38][39]
On July 9, 2025, SIASUN expanded its humanoid lineup with two wheeled humanoid robots in the Rico (RICO) series, the Rico MR73A and Rico MR73B. The MR73A is configured with 38 driving joints and a dual-arm repeatable positioning accuracy of plus or minus 0.03 mm, and SIASUN positioned the series for four core domains: automotive vehicle manufacturing, electronics and semiconductors, aerospace equipment, and warehousing and logistics.[39][40]
SIASUN exhibited for the first time at automatica 2025 in Munich, one of roughly 500 exhibitors from more than 30 countries, where it presented its DUCO collaborative robots and industrial automation portfolio to European buyers. By 2025 the company listed overseas subsidiaries and regional centers in Germany, Singapore, Thailand, Malaysia, Japan, the United States, Mexico, and other locations.[41]
For the first half of 2025, SIASUN reported revenue of CNY 1.66 billion, essentially flat year over year, with a net loss attributable to shareholders of about CNY 95.4 million. Business mix shifted sharply: industrial robot revenue fell 46.11 percent to CNY 270 million, while automated assembly and inspection line and system integration revenue rose 44.60 percent to CNY 739 million, logistics and warehousing automation rose 10.83 percent to CNY 327 million, and semiconductor equipment revenue declined 15.88 percent to CNY 269 million. As of June 30, 2025, the company held 737 patents, including 458 invention patents.[42]
For the full year 2025, SIASUN reported revenue of approximately CNY 4.122 billion, marginally below the CNY 4.138 billion of 2024, and a net loss attributable to shareholders that widened to roughly CNY 397.9 million, with a basic loss per share of about CNY 0.25. The company also disclosed that it shipped approximately 13,676 robots during the year, a 65 percent increase, and that research and development spending reached approximately CNY 364 million, equal to 8.84 percent of revenue. Semiconductor equipment generated roughly CNY 525 million of revenue for the full year.[2][4][38]
In May 2026, SIASUN announced that nearly 100 of its heavy-payload industrial robots had been deployed across the welding main line at the Geely Yiwu manufacturing base, an installation that Chinese industry coverage described as the first time domestically made robots had taken over an automotive body welding main line at scale. The deployment is detailed in the section on automotive welding below.[43][44][45]
Qu Daokui (曲道奎) founded SIASUN in 2000 and served as its president and CEO through to his retirement in 2024. He holds a master's degree from the Shenyang Institute of Automation under the Chinese Academy of Sciences and has been described as both a researcher and a senior executive in the Chinese robotics establishment. In addition to running SIASUN, Qu held several influential industry positions, summarized in the table below.[7][18]
| Role | Organization |
|---|---|
| Deputy director | National Engineering Research Center of Robotics |
| Head | National Robotics Standardization General Working Group of China |
| Chair | China Robot Industry Innovation Alliance |
| President | China Robot Industry Alliance |
| Ph.D. advisor | Chinese Academy of Sciences |
Under Qu's leadership, SIASUN went from a CAS spin-off to a publicly traded national champion with billions in revenue and a manufacturing footprint that included China's largest robotic industrial base. His public statements, including those at the opening of the Shenyang industrial park and at successive World Robot Conferences, framed SIASUN as part of a broader push to anchor the country's high-end manufacturing on domestic robotics rather than imported industrial automation. Qu retired from his executive role in 2024 according to industry coverage of the Chinese robotics sector.[8][15]
SIASUN trades under ticker 300024 on the Shenzhen Stock Exchange's ChiNext board. The Shenyang Institute of Automation of the Chinese Academy of Sciences is the largest shareholder, holding approximately 25 percent of outstanding shares according to 2023 disclosures. The remainder of the float is dispersed across Chinese institutional investors, retail shareholders, and other holdings. The company has periodically been included in Chinese state-aligned high-technology equity baskets and is closely tracked as a proxy for domestic robotics policy outcomes.[6][7]
For the full year ending December 31, 2024, SIASUN reported revenue of CNY 4,138.49 million, up 4.33 percent from CNY 3,966.59 million in 2023. The company recorded a net loss of CNY 193.68 million in 2024, reversing the modest net income of CNY 48.57 million reported in 2023. Basic loss per share from continuing operations was CNY 0.1244 in 2024 compared with basic earnings per share of CNY 0.0313 in 2023. The shift from net income to net loss reflected pricing pressure in the domestic industrial robot market, where Chinese suppliers have engaged in aggressive volume expansion, as well as continuing investment in mobile robot, semiconductor, and humanoid platforms that have yet to reach scale-up margins.[2][4]
For the full year ending December 31, 2025, SIASUN reported revenue of approximately CNY 4,122 million, broadly flat against 2024, while the net loss widened to approximately CNY 397.9 million, with a basic loss per share of about CNY 0.25. The deeper loss came even as unit shipments rose about 65 percent to roughly 13,676 robots, underscoring how heavy domestic price competition and continued investment in newer platforms outweighed volume gains. Research and development spending of approximately CNY 364 million represented 8.84 percent of revenue for the year.[2][4][38]
| Fiscal year | Revenue (CNY mn) | Net income (CNY mn) | EPS (CNY) |
|---|---|---|---|
| 2023 | 3,966.59 | 48.57 | 0.0313 |
| 2024 | 4,138.49 | -193.68 | -0.1244 |
| 2025 | 4,122 (approx.) | -397.9 (approx.) | -0.25 (approx.) |
Despite the back-to-back net losses, SIASUN's top-line revenue places it among the highest-revenue robotics companies in China by reported sales. The company's competitive position is shaped by the volume momentum of pure-play industrial robot specialists such as Estun and the vertical integration of motion-control suppliers such as Inovance.[19][38]
SIASUN groups its products into three core families with independent intellectual property: industrial robots, mobile robots, and special robots. On top of these the company has built solution stacks in welding automation, assembly automation, and logistics automation, plus newer categories that include cleanroom vacuum robots, collaborative robots under the DUCO sub-brand, medical and service robots, and bipedal humanoid robots.[1][20]
The SR series is SIASUN's flagship industrial robot family. It includes articulated six-axis arms and SCARA models that are deployed in welding, material handling, assembly, palletizing, painting, screw fastening, gluing, and machine tending across automotive, electronics, and general manufacturing customers.

The GCR series is certified by TUV SUD and references IEC 61508 functional safety, with three stop categories defined according to IEC 60204-1 (Stop Categories 0, 1, and 2). Optional IP54 and IP65 protection ratings extend deployment into wet or dusty environments. Communication interfaces on representative models such as the GCR16-2000 include TCP/IP, Modbus TCP, Profinet, Ethernet/IP, and RS485, supporting PLC connectivity, gripper control, and conveyor coordination.[24][25]
SIASUN is one of the world's largest AGV and AMR producers by deployed fleet size. The company reports more than 100 distinct mobile robot models across 10 categories, addressing whole-industry and all-scenario applications in smart manufacturing. Export deployments span 40 or more countries and regions, and thousands of project cases are documented across automotive, electronics, semiconductor, new energy, pharmaceuticals, and general logistics segments. The mobile robot business operates in part through the subsidiary Shenyang Siasun Robot Automation Co., Ltd. (en.siasunagv.com).[14][26]
The SIASUN mobile robot family includes transporting-type mobile robots, fork-lift mobile robots, heavy-payload mobile robots, cleaning robots, auxiliary assembly mobile robots, chassis-marriage mobile robots, Mecanum-wheel compound robots (for example the MHR360), and customized hybrid robots. Mobile robots transport raw materials, packaging materials, and semi-finished products from buffer areas to production lines, and they move palletized finished goods between buffers and automated storage and retrieval systems. All deployments are coordinated through the IMRS 2.0 platform, which supports multi-robot dispatching, route optimization, data analytics, and digital twins for end-to-end intelligent control.[26][27] See related platforms for industrial robot coordination.
The IMRS 2.0 (also written iMRS 2.0) platform was formally relaunched as a mobile-robot-centric control system that supports cross-platform integration, multiple languages, and multiple vehicle models, with multi-protocol support spanning the VDA5050 standard, the China Mobile Robot (AGV/AMR) Industry Alliance protocol, and SIASUN's proprietary protocol. The platform is designed for large-scale, mixed-fleet dispatching of up to thousands of units and is organized into six sub-modules covering rapid deployment, early-stage evaluation and forecasting, intelligent operation, and later-stage analytics.[46]
SIASUN has continued to expand mobile robot exports into overseas new energy supply chains. In late November 2024, the company shipped more than 100 mobile robots, including hover-lifting and dual-arm lifting models, to a battery manufacturer in India that aimed to become the country's first super lithium battery enterprise, a deployment SIASUN described as its first bulk entry into the Indian new energy market. The dual-arm lifting robots used a dual-elevation structural design with high-precision motion control and were customized with adjustable widths to handle different battery coil specifications.[47]
Heavy-duty mobile robots developed by SIASUN are used in military, aerospace, smelting, and large-scale logistics applications. In 2010, the company successfully developed a heavy-duty mobile robot with a maximum load capacity of up to 20 tons, the first of its kind in China and at the time positioned by company management as reaching internationally leading performance indicators.[28]
SIASUN's vacuum and cleanroom robot family is built for wafer and substrate transfer inside semiconductor manufacturing tools, where contamination control, repeatable positioning, and low outgassing are critical. Several product lines target different stages of the front-end and back-end fab process flow.[29][30]
| Product line | Description |
|---|---|
| PHOENIX series | Family of vacuum transfer robots that move wafers between load locks and process chambers while maintaining vacuum and cleanliness |
| PHOENIX-S25 series | Direct-drive vacuum manipulators with no internal belts or gears, designed for cleanroom contamination control, hardware interrupt I/O, and tighter automation integration |
| Archer series | Vacuum-environment transfer robots for wafer or substrate handling inside vacuum tools used in semiconductor and high-precision manufacturing workflows |
| SM12 | Vacuum-capable robotic manipulator for high-cleanliness, precision material handling in semiconductor and optoelectronics manufacturing |
| SRBZ820C and SRBZ820C-G | Vacuum cleanroom robots described by vendor listings as SEMI-certified solutions emphasizing magnetic-fluid sealing, steel-belt transmission, and high MCBF reliability for automated vacuum transfer |
These platforms compete with offerings from international vacuum-robot suppliers such as Brooks Automation, Yaskawa, and other semiconductor equipment specialists in domestic Chinese fabs. They are a strategic product line for SIASUN given the policy importance attached to localizing semiconductor equipment supply chains. Semiconductor equipment generated approximately CNY 525 million of revenue for the company in 2025.[29][30][38]
SIASUN develops specialized robotic platforms for applications that fall outside conventional industrial environments. The category includes vacuum cleanroom transport units for semiconductor and aerospace cleanrooms, heavy-load mobile robots for military and aerospace logistics, laser-based equipment for precision manufacturing, automated assembly machines, and various customized robots for national defense customers. The CNY 169.2 million special-robot contract signed in December 2014 illustrates the scale at which the company has supplied defense-adjacent automation. Heavy-duty mobile robots with up to 20-ton load capacity, originally developed in 2010, anchor this segment.[28][3]
SIASUN's humanoid robot family was formally introduced at the 2025 World Robot Conference and is built around four platforms: the Songxing bipedal humanoid, the Songyi wheeled humanoid, the RICO wheeled humanoid for material handling, and an intelligent humanoid dual-arm platform. The Duoke service robot, marketed as a coffee robot, sits alongside this family as an entry into hospitality service automation. SIASUN's humanoid program is anchored by the SIASUN Embodied Intelligence Research Institute, established on April 30, 2025 to concentrate the company's work on AI large language models, multimodal perception, and autonomous decision-making for embodied systems.[16][17][38][39]
The Songxing (松行) is SIASUN's flagship bipedal humanoid robot. Its core technology stack is described as independent and controllable, with self-developed core components and underlying control systems that achieve fine-grained robot atomic operation capabilities across multiple categories. Through reinforcement learning and imitation learning techniques, motors in the arms, waist, and feet are controlled to collaborate in anthropomorphic movement of bionic joints.[17]
Key attributes published by SIASUN include:
The Songyi (松翼) wheeled humanoid integrates a mobile robot base with a dual-arm system and AI-driven decision making. It is designed for warehousing and logistics, new retail, and home services, supports multi-task parallel execution, and performs grasping, handling, sorting, and stacking at different heights.[16]
The RICO wheeled humanoid focuses on material handling and is developed under the SIASUN DUCO brand. On July 9, 2025, SIASUN extended the line with two wheeled humanoids, the Rico MR73A and Rico MR73B. The MR73A carries 38 driving joints and a dual-arm repeatable positioning accuracy of plus or minus 0.03 mm, and the series is targeted at four core domains: automotive vehicle manufacturing, electronics and semiconductors, aerospace equipment, and warehousing and logistics. The intelligent humanoid dual-arm platform is a research and integration platform that combines two collaborative arms with mobile bases for flexible deployment; at the 2025 World Robot Conference SIASUN demonstrated this platform completing tasks such as operating a water dispenser through multimodal AI interaction, illustrating coordination between perception, planning, and dual-hand manipulation.[16][38][39][40]
Beyond the major families above, SIASUN develops cleanroom, medical, and service robots used in pharmaceuticals, hospital logistics, retail, and consumer-facing scenarios. Application packages cover automated drug warehousing, hospital material transport, and other tasks that benefited from accelerated adoption following the COVID-19 pandemic.[1][3]
SIASUN maintains a substantial in-house engineering organization that registered approximately 140 inventions per year between 2013 and 2016. Core technical capabilities span several domains.[3][21]
SIASUN benefits from access to the National Engineering Research Center of Robotics, where founder Qu Daokui served as deputy director, and from continuing collaboration with the Shenyang Institute of Automation. The company has stated plans to expand research and development capacity through dedicated centers in Europe, North America, and Japan. In 2025, the company spent approximately CNY 364 million on research and development, equal to 8.84 percent of revenue, and reported 737 patents including 458 invention patents as of mid-year. The SIASUN Embodied Intelligence Research Institute, opened in April 2025, focuses the company's embodied AI work on large language models, multimodal perception, and autonomous decision-making.[3][7][38][39][42]
SIASUN operates its headquarters and primary manufacturing base in Shenyang, with additional industrial parks in Shanghai, Qingdao, Tianjin, and Wuxi. The Shenyang base, opened in October 2017 at a cost of approximately USD 302 to 303 million, includes a headquarters building, an exhibition center, a research and development center, and multiple manufacturing centers. With an annual production capacity exceeding 10,000 robot sets, it integrates industrial robots, intelligent equipment, and information technology across product design, production, quality, and logistics processes, including what Chinese state media described as the first national demonstration project for Industry 4.0 manufacturing.[1][8][13]
Internationally, SIASUN operates a manufacturing facility in Thailand's Eastern Economic Corridor, which it and Thai government partners have described as Southeast Asia's first 5G smart factory. The Thai facility supports automotive and electronics customers in the region and was the company's first overseas manufacturing operation, with construction beginning in 2019.[14][3]
SIASUN reports more than 30 international subsidiaries and regional centers. As of 2025 the company listed overseas subsidiaries and regional centers in Germany, Singapore, Thailand, Malaysia, Japan, the United States, Mexico, and other locations. Key international entities and their headquarters locations are listed below.[1][31][41]

SIASUN's products have been exported to more than 40 countries and regions globally and have served more than 4,000 international companies through over 18,000 project deployments. The company has maintained formal cooperation with 17 Belt and Road Initiative nations. In June 2025 it exhibited for the first time at automatica in Munich, Europe's leading smart automation and robotics fair, as part of a broader export push.[1][3][41]
SIASUN serves customers across automotive, electronics and semiconductor, new energy, pharmaceuticals, military, and general manufacturing sectors. Two thirds of customers are large organizations, with many Fortune Global 500 names among them.[1]

In automotive welding, SIASUN's industrial robots and DUCO cobots have been used on weld cells, line-side assembly, powertrain handling, and just-in-time intralogistics. In electronics and semiconductor production, vacuum manipulators have supplied wafer handling and substrate transport inside vacuum tools.[22][30]
In a milestone publicized in May 2026, SIASUN deployed nearly 100 heavy-payload industrial robots across the welding main line at the Geely automotive group's Yiwu manufacturing base. The installation spanned the body main weld line, the lower-body line, the left and right front door lines, and the side-frame line, and covered more than 95 percent of the mainstream processes used on an automotive welding line. Chinese industry coverage described it as the first time domestically produced robots had taken over an automotive body welding main line at this scale, breaking a segment that had long been treated as an exclusive preserve of foreign suppliers.[43][44][45]
The fleet combined multiple SIASUN models, including 12 kg, 210 kg, and 360 kg payload classes. As part of the project, SIASUN and Geely co-developed two new heavy-payload spot-welding robots, the SR210A-210/2.65 and the SR500A-360/2.83, that achieved a welding position error of 0.06 mm or less and a mean time between failures of at least 80,000 hours. SIASUN stated that the controllers, control systems, servo motors, and drives were either developed in house or sourced from Chinese suppliers, removing dependence on imported core components. The project also integrated spot welding with self-piercing riveting (SPR) and flow-drill screw (FDS) joining, used PDPS-based virtual commissioning, and cut single-robot commissioning time from tens of days to roughly four days through offline programming and simulation.[43][44][45]
SIASUN occupies a privileged position in Chinese industrial policy. The Shenyang Institute of Automation of CAS is the largest shareholder, and the company has long been listed among the national champions in the country's high-end manufacturing strategy. Beijing's Made in China 2025 plan, published in 2015, selected high-end numerical control machinery and robotics as one of ten priority sectors. SIASUN, together with Estun, EFORT Intelligent Equipment, JAKA, Dobot, and Elite Robots, has been supported by government subsidies, purchasing incentives, and procurement programs that aim to raise the domestic supply share of industrial robots used in Chinese factories.[32][33]
Government programs have also supported Chinese acquisitions of foreign robotics firms, most prominently the 2016 Midea acquisition of KUKA. For domestic suppliers including SIASUN, this policy environment has translated into a captive purchasing pipeline through state-owned enterprises and a steady research and development funding base. In 2024, 52 percent of industrial robots sold in China were manufactured by domestic suppliers, up from 47 percent in 2023, with the share continuing to rise into 2025. International players such as ABB Robotics, FANUC, KUKA, and Yaskawa still dominate the premium segment, but Chinese firms including SIASUN, Estun, and Inovance have steadily gained ground in mid-range applications. The 2026 Geely welding main line deployment extended this localization push into automotive body welding, a high-value process previously dominated by foreign robot makers.[33][34][43]
Within China, SIASUN competes with a small set of domestic industrial robot specialists and motion-control suppliers, as well as with a longer tail of cobot and humanoid start-ups. The largest pure-play industrial robot incumbents are Estun, Inovance, and EFORT. As of 2024, Estun held approximately 9.5 percent share of the Chinese industrial robot market and was the largest domestic supplier, while Inovance held 8.8 percent and SIASUN held approximately 6.2 percent. EFORT captured roughly 5.4 percent. Estun's competitive edge is its vertical integration into servo motors, controllers, and motion control systems, reducing dependence on imported components. Inovance, founded in 2003 by former Huawei engineers, formally entered the industrial robot market in 2016 and supplied 27.3 percent of SCARA robots sold in China in 2024.[19][35]
| Company | 2024 China market share | Key positioning |
|---|---|---|
| Estun | Approximately 9.5 percent | Vertically integrated controllers, motors, and arms |
| Inovance | Approximately 8.8 percent | Servo and SCARA dominance, fastest growing |
| SIASUN | Approximately 6.2 percent | Diversified across industrial, mobile, cobot, vacuum, humanoid |
| EFORT | Approximately 5.4 percent | Six-axis industrial arms, palletizing, welding cells |
SIASUN distinguishes itself through breadth of product portfolio rather than depth in any single category. It is one of the few domestic suppliers active in industrial arms, cobots, AGV and AMR fleets, vacuum cleanroom robots, special defense robots, and bipedal humanoids simultaneously. In SCARA and high-volume small industrial arms, Inovance leads. In serial production volume for general industrial arms, Estun leads. In mobile robots, SIASUN remains one of the largest fleets globally. In cobots, Universal Robots remains the international benchmark with SIASUN's DUCO competing on price and payload coverage.[19][35]
In the global market, SIASUN competes against the so-called "Big Four" Japanese and European industrial robot suppliers, who together hold a majority of the world's installed base.[36]
| Competitor | Country | Notable position |
|---|---|---|
| FANUC | Japan | Largest industrial robot supplier globally by installed base |
| ABB Robotics | Switzerland and Sweden | Dominant in arc welding, painting, and general automation |
| KUKA | Germany (owned by Midea since 2016) | Premium automotive robotics, including spot welding |
| Yaskawa | Japan | Servo motors and motion control leadership, Motoman brand |
| Universal Robots | Denmark | Collaborative robot pioneer, dominant in cobot installations |
In the humanoid robot category, SIASUN's Songxing competes against fast-moving Chinese humanoid specialists and against Tesla Optimus, Figure AI, Boston Dynamics, Agility Robotics, Unitree Robotics, UBTECH Robotics, and others. UBTECH, a close domestic peer, began mass production of its Walker S2 humanoid in November 2025 with a first batch of several hundred units, illustrating how quickly the Chinese humanoid field moved into volume during the period SIASUN was building out its own lineup. SIASUN approaches the humanoid market from a position of established industrial robotics depth, particularly in actuator design, motion control, and manufacturing at scale, rather than from a pure AI start-up posture.[16][17][48]
SIASUN has registered over 1,000 patents through its long-running research and development cycle, including roughly 140 invention disclosures per year between 2013 and 2016 and 737 patents (458 inventions) reported as of mid-2025. The company is a participant in Chinese national standards activity, with founder Qu Daokui having led the National Robotics Standardization General Working Group. Cobot safety certification through TUV SUD references international standards including IEC 61508 for functional safety and IEC 60204-1 for machine safety stop categories.[3][24][42]
SIASUN is the romanized form of the Chinese name 新松 (Xinsong), where 新 means new and 松 means pine, evoking durability and growth. In English the name is constructed as a portmanteau of the parent institute (SIA) and the suffix SUN, emphasizing the genealogy from the Shenyang Institute of Automation. The company markets itself with the phrase "industrial intelligence 4.0 beyond automation" on its global website and uses a four-character slogan structure that translates approximately to "Chinese Speed, Chinese Level, Industry-leading, World-class."[1]
Industry analysts generally classify SIASUN as one of three to five domestic Chinese robot manufacturers with comprehensive product portfolios spanning industrial, mobile, and special-purpose categories. The Wire China has described the company as the first Chinese robotics company to float shares publicly, noting its institutional backing from the Chinese Academy of Sciences and its market capitalization in the multibillion-dollar range. Asian Robotics Review and other trade publications have identified SIASUN as a national champion under Made in China 2025 and a key beneficiary of state procurement and subsidies. Critics have pointed to softening profitability, including SIASUN's 2024 and 2025 net losses, as a sign of intensifying domestic price competition.[6][33][2][38]
SIASUN's 2024 financial reversal occurred against the backdrop of record-high industrial robot installations in China, which crossed 295,000 units that year and represented 54 percent of global deployments according to the International Federation of Robotics. Domestic suppliers including SIASUN, Estun, and Inovance collectively gained share, but the volume gains came alongside aggressive pricing that compressed margins across the segment. The pattern continued through 2025, when SIASUN's unit shipments rose about 65 percent to roughly 13,676 robots even as the net loss widened, a divergence that captured the broader squeeze facing Chinese industrial robot makers as they traded margin for volume and invested heavily in next-generation humanoid and embodied AI platforms.[37][34][38]
