SIASUN GCR Series Cobots are six-axis collaborative robots developed by Siasun Robot & Automation Co., Ltd. (also branded “DUCO” on certain international pages). The GCR line targets human-robot collaboration in factory and lab settings, combining force-limited design, simplified programming, and compact footprints for on-line deployment without traditional fencing. Official product materials position the series for multi-industry tasks such as assembly, machine tending, quality inspection, painting, and polishing.

Family overview

The GCR family includes at least the following models (naming indicates nominal payload and reach class): GCR3-618, GCR5-910, GCR7-910, GCR10-1300, GCR12-1300, GCR16-960, GCR16-2000, GCR20-1400, GCR25-1800, GCR30-1100. This matrix spans short-reach, high-speed arms for electronics to longer-reach or higher-payload units for handling and assembly. 

Collaborative safety and ergonomic deployment

Cobot-specific design elements include power-and-force limiting joints, collision detection, and support for risk-reduction features such as emergency stop categories and protective stops. The series is intended to be mounted in any orientation (table, wall, ceiling) to fit existing stations with minimal rework. Teach pendants and “traction-teach” (hand-guiding) streamline path creation and redeployment, which is useful for high-mix/low-volume environments. 

Environmental protection and robustness

Model pages list IP54/IP65 protection options, adding dust/splash resistance for shop-floor reliability. Repeatability figures (down to ±0.02–0.03 mm on certain models) position GCR cobots for precision inspection and light process tasks. 

Technology and Specifications

While performance varies by model, public specifications highlight several core aspects:

  • Kinematics and degrees of freedom: 6-axis architecture across the line enables standard industrial poses and compact elbow maneuvers for crowded cells. 

  • Reach / payload classes: Examples include GCR5-910 (5 kg payload, 917 mm reach) and GCR10-1300 (10 kg, 1300 mm), with speed specs up to 3.6–3.8 m/s TCP and straight-line speeds around 1.5 m/s. Heavier units (e.g., GCR12-1300) maintain comparable reach and protection classes. 

  • Repeatability: Representative values include ±0.02 mm (GCR5-910) and ±0.03 mm (GCR10-1300 / GCR12-1300). Such precision supports electronics handling and gauging tasks. 

  • Safety functions: The user manual documents Stop Categories 0/1/2, protective stop, and Safe Operating Stop (SOS). It explains that the safety system monitors violations and may initiate Category 0 (power removal) if faults are detected. It also details collision-detection limitations in specific zones, guiding integrators on risk assessment.

  • I/O and power: Third-party distributor data lists low typical power consumption (≈200–500 W depending on model) and cabinet/tool I/O for gripper and sensor integration, supporting economical operation and quick end-effector swaps.

Illustrative parameters
• GCR5-910: 5 kg payload, 917 mm reach, ±0.02 mm repeatability, up to 3.6 m/s TCP; IP54/IP65. 
• GCR10-1300: 10 kg payload, 1300 mm reach, ±0.03 mm repeatability, up to 3.8 m/s TCP; IP54/IP65. 
• GCR12-1300: 12 kg payload, 1300 mm reach, ±0.03 mm repeatability; up to 3.8 m/s TCP; IP54/IP65. 

The manual also covers singularity behavior (shoulder, elbow, wrist) and recommends reduced speed or joint-space motions near singularities—important for safe collaborative programming. 

Applications and Use Cases

Assembly & screwdriving. Repeatability in the hundredths-of-a-millimeter range and integrated I/O support common torque tools and feeders, aiding fast changeovers in consumer electronics and light mechanical assembly. 

Machine tending. Cobots can service CNCs, molding presses, or test rigs with hand-guiding setup and small footprints that fit existing cells, reducing fixture redesign and enabling off-shift lights-out cycles. 

Quality inspection & vision tasks. Stable, repeatable paths and IP-rated designs suit surface inspection, gauging, and camera-based checks adjacent to production lines. 

Painting, polishing, and finishing. Model cards explicitly reference these processes; the lightweight arms and safety functions enable closer human supervision and finishing of small batches without cages. 

Automotive sub-assembly and adhesives. Case notes show GCR deployments for welding/gluing of body parts, where cobots can manage sealant beads or fixture handling alongside human operators. 

Advantages / Benefits

  1. Fast deployment and redeployment. Hand-guiding (“traction-teach”) and simplified UIs cut setup time for pilots and seasonal SKUs. 

  2. Safety functions aligned to standards. Documented stop categories, protective stops, and guidance on risk zones support compliant collaborative applications.

  3. Broad model coverage. Ten+ variants allow right-sizing by payload/reach without leaving the platform family, simplifying spares and training. 

  4. Industrial protection and precision. IP54/IP65 options and sub-0.03 mm repeatability open inspection and light process work on the shop floor. 

  5. Ecosystem fit. Native interoperability with Siasun’s industrial robots and AMR/AGV fleets supports end-to-end workflows from material delivery to on-station operations. 

Comparisons (if relevant)

Compared with traditional six-axis industrial arms, GCR cobots emphasize power-and-force limiting, simplified UI, and fast changeovers, trading absolute speed or payload for safe human proximity. In the broader collaborative market (e.g., offerings from other global vendors), differentiators for the GCR series include its wide span of models within one family, IP54/IP65 configurations on select variants, and documentation of safety categories and collision-detection considerations—useful for risk assessment during CE/ISO conformity processes. (Specifications and safety implementations should always be validated per model and local regulations.) 

Pricing and Availability

List pricing is typically project-specific and varies with payload class, reach, end-of-arm tooling, vision, and safety/IO options. Distributors in multiple regions list GCR models and provide quotation on request; public reseller pages also share typical power and IO characteristics. Siasun’s corporate site cites global exports and thousands of project cases, indicating multi-region availability and service coverage. 

FAQ Section

What is the SIASUN GCR Series?
A family of six-axis collaborative robots spanning 3–30 kg classes (model-dependent) designed for safe human-robot workflows in assembly, tending, inspection, painting, and polishing.

How does a GCR cobot work?
GCR cobots use servo-controlled joints with force-limiting and collision-detection features. Programs can be taught via pendant or hand-guiding; safety functions such as protective stop and Stop Categories 0/1/2 help mitigate risk when correctly configured. 

Why are GCR cobots important?
They provide a bridge between manual stations and fenced automation, enabling incremental productivity gains, consistent quality, and lower integration overhead for high-mix manufacturing.

What are the benefits of GCR cobots?
Rapid deployment, robust safety features, precision (±0.02–0.03 mm on representative models), optional IP54/IP65 protection, and a broad range of payloads and reaches in a single platform family.
