SIASUN

Introduction / Overview

SIASUN Robot & Automation is where Chinese robotics grew up. Founded in 2000 by roboticist Qu Daokui out of the Chinese Academy of Sciences' Shenyang Institute of Automation, SIASUN became "China's first robot stock" (Shenzhen: 300024) and remains the country's institutional standard-bearer — a ~CNY 25.7 billion public company whose machines weld the nation's cars, ferry its factory chassis, handle its semiconductor wafers, and now walk its exhibition halls. The strategy is codified as "3+3+N": three core product fields — industrial robots, mobile robots, and special robots — deepened by three application technologies — welding, assembly, and logistics automation — deployed across N strategic industries. The distinguishing trait is process depth: SIASUN doesn't just sell arms, it delivers turnkey lines where robots, fixtures, sensors, software, and quality systems arrive as one solved problem.

The portfolio's breadth is unmatched in your catalog. Industrial robots run from desktop and SCARA units through six-axis arms to ultra-high-payload machines — the SR270A (270 kg / 2.70 m) handling automotive spot welding, gluing, stud welding, and SPR joining, and famous for dancing with human performers at a CCTV gala in millisecond synchronization. The mobile-robot business is historic: SIASUN pioneered the automotive assembly AGV — the "marriage station" vehicles lifting chassis to body in final assembly, plus engine, rear-axle, and transmission assembly platforms — exported to global automakers for decades, joined today by container-handling AMRs and industrial cleaning robots. Special robots serve nuclear, defense-adjacent, and semiconductor vacuum/cleanroom missions. And the 2025–26 pivot is embodied: an Embodied Intelligence Research Institute, the "Songxing" bipedal humanoid and "Songyi" wheeled humanoid — LLM-integrated platforms understanding natural language with multimodal perception, Songyi pairing SIASUN's mature wheeled base with a high-performance dual-arm system for warehousing, new retail, and home services — plus EU CE Marking on the new industrial-robot generation now deploying into UK and French power-battery plants, and a Thailand subsidiary anchoring regional expansion. For manufacturers who need a robotics institution rather than a startup, SIASUN is the reference choice.

Design and Features

Industrial Robots — Desktop to 270 kg

• The full payload ladder — SCARA and desktop units for electronics pick-and-place, small- and mid-payload six-axis arms for general manufacturing, and large-to-ultra-high-payload machines (the SR270A class) for automotive body shops — one vendor across every motion profile in a plant.
• Process-complete welding — arc, laser, and spot welding plus grinding and automated assembly delivered as integrated solutions, the application depth behind SIASUN's automotive benchmark projects.
• Precision with showmanship — millisecond-synchronized gala choreography on a 270 kg industrial arm: motion control demonstrated at broadcast stakes.
• CE-marked for Europe — the new generation certified for EU deployment, already landing in British and French battery gigafactories.

Collaborative Robots

Force-limited, collision-aware cobots with simplified programming for light assembly, machine tending, and finishing — engineered for fast redeployment as lines and SKUs shift.

Mobile Robots — The AGV Pioneer

• Automotive assembly heritage — the chassis-body "marriage" lifting AGVs and engine/rear-axle/transmission assembly platforms (lifting, flipping, extending, transferring) that made SIASUN a fixture in final-assembly halls worldwide — decades before "AMR" was a word.
• Modern intralogistics — container-handling mobile robots with precise navigation and modular tooling, warehouse and line-side AMR fleets replacing fixed conveyors, and industrial cleaning robots purpose-built for factory floors.

Special Robots

Nuclear, hazardous-environment, and semiconductor vacuum robots — the cleanroom wafer-handling class where SIASUN carries rare domestic capability — extending the company into missions standard automation cannot enter.

The Embodied Turn — Songxing and Songyi

• Songxing — the bipedal humanoid: SIASUN's Physical-AI flagship walking the company into full-form embodied intelligence.
• Songyi — the pragmatic wheeled humanoid: SIASUN's mature mobile platform fused with a high-performance dual-arm system and an embodied intelligent system providing environmental perception, natural-language understanding, and multimodal task planning — aimed at warehousing/logistics, new retail, and home services.
• The Institute — a dedicated Embodied Intelligence Research Institute institutionalizing the AI-robotics program the humanoids ride on.

Technology and Specifications

The Range at a Glance

Model-level specifications vary widely across this portfolio; confirm current datasheets before specifying — datasheets are available on request.

Why Institutional Depth Matters

Robot adoption usually fails at integration, not hardware — and SIASUN's quarter-century of turnkey delivery (fixtures, software, sensors, quality, operators) is precisely the de-risking that startups cannot offer. The 2026 productization push aims that depth at standardized, faster-deploying offerings — institutional reliability at catalog speed.

Position in the Market

Against component-volume rivals like ESTUN, SIASUN leads in intelligent systems, turnkey automotive solutions, and specialized mobile robots; within your catalog it is the only brand spanning industrial arms, assembly AGVs, semiconductor special robots, and humanoids — the single-vendor answer for buyers consolidating suppliers.

Applications and Use Cases

Automotive Manufacturing

The heartland: welding lines, SPR joining, assembly AGV fleets, and marriage stations across body and final assembly — now extending into European battery plants.

Electronics and General Manufacturing

SCARA precision, desktop cells, and cobot tending across 3C, metal processing, and new-energy production.

Intralogistics and Warehousing

AMR fleets, container handlers, and industrial cleaning robots — with Songyi's dual-arm handling entering the picture.

Semiconductors and Special Environments

Vacuum wafer-handling robots and hazardous-environment platforms serving fabs and critical infrastructure.

Embodied-AI Services

Songxing and Songyi pilots across logistics, new retail, and service scenarios on LLM-native task understanding.

Advantages / Benefits

• China's robotics institution — CAS lineage, first-robot-stock status, and 25 years of turnkey delivery.
• The widest portfolio in your catalog — desktop arms to 270 kg, AGVs to vacuum robots to humanoids, one accountable vendor.
• Automotive AGV pedigree — the assembly-vehicle category SIASUN effectively invented, proven in global plants.
• Process depth over parts — welding, assembly, and logistics delivered as solved systems, not shipped components.
• European door open — CE-marked new generation deploying into UK/French gigafactories.
• An embodied future funded — a dedicated research institute and two humanoid platforms already public.

For buyers researching where to buy SIASUN robots, or comparing industrial arm, AGV, and Songyi prices and costs against other industrial and embodied brands, the evaluation should weigh portfolio breadth, integration depth, automotive pedigree, certification coverage, and institutional stability — the dimensions where SIASUN's quarter-century leads.
