SIASUN Collaborative Robot Arm with 917mm Reach, 5kg Max Payload, 6 DOFs (GCR5-910)

Most workshops meet the same dilemma when they automate a manual station. A fenced industrial robot is fast but takes floor space and isolates the operator, while a slow, gentle arm keeps people close but rarely keeps pace with production. The SIASUN Collaborative Robot Arm with 917mm Reach, 5kg Max Payload, 6 DOFs (GCR5-910) is built to narrow that gap. It offers a maximum TCP speed of 3.6m/s and repeatability of ±0.02mm, and it carries 16 TUV-certified safety features so that it can share a workbench with the people beside it.

Robots Europa, based in Dublin, supplies the GCR5-910 to integrators, manufacturers and research groups throughout the European Union and the DACH region. Robots Europa prepares each quotation, arranges delivery to your site and remains your point of contact for support once the arm is in service.

Background

SIASUN and the GCR series

SIASUN is a robotics manufacturer whose catalogue covers several classes of machine. These include heavy industrial arms, palletising robots and the GCR family of collaborative robots. The manufacturer describes the GCR5-910 as a high-end, general-purpose collaborative robot within the GCR series. The sources name further versions alongside it: the GCR5-910-W, the GCR3-618 and the GCR3-618-W. Every value on this page refers to the GCR5-910 alone. Buyers who need the larger industrial machines from the same manufacturer will find them in our Robot Arms category.

Positioning: perception and simplicity in one arm

The GCR5-910 combines 2D/3D vision depth fusion with high-sensitivity force perception and control. In practice, the arm can be set up to locate parts, respond to contact and adjust its behaviour accordingly. These are the abilities that separate a collaborative cell from a fixed, blind routine. SIASUN pairs this sensing with drag-and-drop teach programming, which lowers the threshold for operation: staff can guide the arm by hand to teach a path rather than writing every move as code. Scenario-specific software packages, multiple external interfaces, cloud-based robot data monitoring and remote OTA upgrades complete the platform.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation.

The manufacturer has not published the specific communication interfaces, the contents of the box, the operating noise, the robot cable length or a joint-by-joint speed table; these details are confirmed at quotation.

How do speed and precision sit together in a collaborative robot?

Collaborative robots are often assumed to trade performance for safety. The GCR5-910 puts that assumption to the test. A maximum TCP speed of 3.6m/s gives the arm quick repositioning between tasks. A maximum straight-line speed of 1.5m/s describes how it moves when it follows a linear path, for example along a weld seam or a bead of adhesive. Repeatability of ±0.02mm means that the arm returns to a taught point with the consistency that screw fastening, assembly and inspection demand.

Safety comes from the 16 TUV-certified safety features designed for human-machine collaboration, supported by force perception. A cobot works safely beside people because it senses contact and limits its behaviour when someone is in the workspace, and this does not prevent it from moving quickly when it can. As with every collaborative installation, the actual speeds permitted in a given cell depend on the risk assessment for that application. Robots Europa can discuss this with your integrator when preparing the quotation.

The 917mm reach and 5kg payload place the arm in the middle of the collaborative class. It covers a typical workbench or machine door and carries a gripper, a screwdriver, a camera or a light spindle together with the workpiece. The IP54/IP65 classification indicates protection against dust and water, which matters in grinding, polishing and oiling cells.

What does the software layer add to the GCR5-910?

Hardware sets the limits, but software decides how quickly a cell earns its keep. SIASUN supplies the GCR5-910 with a variety of scenario-specific software packages, so common tasks such as picking, welding or gluing begin from a prepared framework rather than a blank program. Drag-and-drop teaching makes later adjustments practical for production staff, which helps when product variants change frequently.

Cloud-based robot data monitoring lets engineers follow the condition and activity of the robot without standing beside it. Remote OTA upgrades allow the control software to be updated without a site visit. For companies running several cells, or for integrators maintaining installations on behalf of clients, these functions reduce the effort of keeping a fleet current. Multiple external interfaces support connection to peripherals and plant systems, and Robots Europa can check them against your existing equipment when preparing your proposal.

Who is the GCR5-910 for?

The arm suits manufacturers automating a manual station for the first time. In that setting, drag-and-drop teaching and collaborative safety lower the barrier to entry, and the arm can often join an existing line without major rebuilding. It also suits system integrators who need a general-purpose cobot that they can configure for picking, welding, assembly or finishing with the help of SIASUN's software packages.

Quality and laboratory teams form a third group. The combination of 2D/3D vision depth fusion and force perception supports inspection and contact-sensitive tasks, while ±0.02mm repeatability keeps measurements consistent. Universities and research institutes may value the same sensing and the cloud monitoring for experiments in human-robot collaboration.

The sources list further versions of the GCR series, the GCR5-910-W, GCR3-618 and GCR3-618-W, and Robots Europa can compare them with the GCR5-910 on request. Projects that need far heavier payloads or palletising are better served by the industrial machines in our Factory Robots category.

What is the GCR5-910 used for?

1. Intelligent picking – vision depth fusion helps the arm locate and pick parts that are not presented in fixed positions.
2. Welding – controlled straight-line motion supports consistent paths along seams.
3. Loading and unloading – the arm tends machines and fixtures, freeing operators for higher-value work.
4. Assembly and screw fastening – repeatability and force perception support accurate placement and controlled tightening.
5. Polishing and grinding – force control maintains contact with the surface, protected by the IP54/IP65 classification.
6. Quality inspection – combined 2D/3D vision and precise positioning give repeatable inspection of parts, alongside related tasks such as gluing and oiling.
