SIASUN GCR3-618 (GCR3-618)

Most automation projects begin with a compromise: either the machine is fenced off and fast, or it shares the bench and does little. The SIASUN GCR3-618 (GCR3-618) is built to avoid that compromise. It is a small six-axis arm intended to stand where an operator stands, take over the repetitive part of a task and repeat it with ±0.02mm repeatability, without asking the workshop to be rebuilt around it. For a production manager weighing up a first cobot, or a laboratory looking for a precise arm that people can work next to, the question is less whether such a robot exists than whether this one fits the cell, the team and the process.

Robots Europa, based in Dublin, supplies the SIASUN GCR3-618 (GCR3-618) to customers across the European Union and the DACH region. We prepare quotations, coordinate delivery into the EU and provide the point of contact for support after installation, so that integrators, manufacturers and research institutions can source the arm from a single European partner.

Background

SIASUN and the DUCO sub-brand

SIASUN is a robotics manufacturer with a broad portfolio that extends from collaborative arms to heavy-duty mobile platforms and complete automation solutions. Its collaborative work is carried by SIASUN DUCO, a sub-brand focused on intelligent robotics. The manufacturer states that SIASUN DUCO has broken foreign technology monopolies in several fields and that all of its core components are developed in-house. For a buyer, in-house development of the core components matters in practical ways: the drive, the sensing and the control software come from the same engineering organisation, which tends to simplify questions of compatibility and long-term support.

Positioning within the GCR series

The GCR3-618 is described by SIASUN as a high-end, general-purpose collaborative robot in the GCR series. The sources name several versions in this family, including the GCR3-618, the GCR3-618-W, the GCR5-910 and the GCR7-910, and the wider range of SIASUN GCR series cobots covers a span of sizes. The GCR3-618 sits at the light-payload end of that family. Its position is not that of a stripped-down entry model: it carries the same emphasis on vision, force perception, certified collaborative safety and cloud-connected software that defines the series, in a format suited to compact workstations.

Technical Specifications

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

The manufacturer has not published the net weight, the power supply and consumption, the specific communication interfaces, the package contents or the model of the controller and teach pendant; these details are confirmed with your quotation.

What sets the GCR3-618 apart among compact cobots?

Small collaborative arms are often chosen because they are easy to place, and then found wanting because they cannot perceive what they are handling. The GCR3-618 addresses that gap by combining 2D/3D vision depth fusion with high-sensitivity force perception and control. In practice, this combination allows an application to locate a part visually and then handle it with controlled contact, which is the difference between a robot that merely moves to coordinates and one that can cope with the small variations found on a real bench.

Safety is the second distinguishing point. SIASUN specifies 16 TUV-certified safety features for human-machine collaboration. Certified safety functions do not replace the risk assessment that every European installation requires under the Machinery Directive and CE marking obligations, but they give the integrator a documented foundation on which to build that assessment. A collaborative cell still has to be evaluated as a whole, including the gripper, the workpiece and the surrounding equipment.

The third point is the operating environment. With an IP class of IP54/IP65, the arm is specified for settings where dust and splashing are part of daily work, which widens its use beyond the clean assembly bench.

How does the GCR3-618 fit into an existing workflow?

A cobot earns its place when the people around it can use it without a specialist on call. SIASUN equips the GCR3-618 with drag-and-drop teach programming, intended to lower the threshold for use and make operation easier. An operator can guide the arm through a movement by hand and record it, which shortens the path from an idea on the shop floor to a running task, and makes redeployment between stations a routine matter rather than a project.

Beyond teaching, the software side is designed for continuity. Scenario-specific software packages provide starting points for common tasks, and support for multiple external interfaces allows the arm to work with grippers, sensors and line equipment. Cloud-based robot data monitoring gives maintenance and production teams visibility of how the robot is running, while remote OTA upgrades allow the software to be updated without a site visit. For organisations with several cells, or with limited on-site engineering capacity, these functions reduce the effort of keeping a fleet consistent.

Who is the SIASUN GCR3-618 (GCR3-618) for?

The arm suits manufacturers automating light, repetitive work at compact stations, particularly small and medium-sized enterprises introducing their first collaborative robot and wanting a model their own staff can teach. System integrators building cells for electronics, consumer goods or precision components will find the combination of vision, force sensing and certified safety functions a useful base for customer projects. Universities, technical colleges and research laboratories may value the arm as a platform for teaching robotics, human-robot interaction and sensor-guided manipulation.

Where a task demands more payload or a longer reach than this compact arm provides, buyers should compare other members of the family, such as the SIASUN GCR5-910 Collaborative Robot Arm or the SIASUN GCR10-1300 Collaborative Robot Arm. Robots Europa can advise on which model matches the workpiece, cycle and workspace.

What is the SIASUN GCR3-618 (GCR3-618) used for?

1. Small-part assembly: inserting, fitting and joining light components at a shared workbench.
2. Quality inspection: presenting parts to cameras or using vision to check features before they move on.
3. Screwdriving and fastening: repeating controlled tightening tasks where force feedback helps consistency.
4. Pick-and-place and machine tending: loading and unloading light parts to keep a machine running.
5. Polishing and surface finishing: applying controlled contact to surfaces where force perception is essential.
6. Education and research: teaching robotics and exploring vision- and force-guided manipulation in the laboratory.

Frequently Asked Questions

What payload and reach does the GCR3-618 offer?

The GCR3-618 has a maximum payload of 3kg and a reach of 618mm. Remember that the gripper or tool counts towards the payload.

Can the GCR3-618 work safely alongside people?

How is the arm programmed?

The GCR3-618 uses drag-and-drop teach programming, which allows operators to guide the arm by hand and record movements. Scenario-specific software packages offer further starting points for common tasks.

Is the GCR3-618 suitable for dusty or wet environments?

The manufacturer gives an IP class of IP54/IP65 for the arm. Please describe your operating environment in your enquiry so that we can advise on the right configuration.

Does the robot support vision and force sensing?

Yes. The arm integrates 2D/3D vision depth fusion with high-sensitivity force perception and control.

Which controller and communication interfaces does it use?
