SIASUN Collaborative Robot (GCR20-1400)

Most factories meet the same dilemma sooner or later: the small bench cobot that suits a shared workspace cannot lift the gripper, the part and the fixture together, while the industrial arm that can lift them needs a fence, a guarded cell and a safety concept of its own. The SIASUN Collaborative Robot (GCR20-1400) is built for that middle ground. It is a high-end, general-purpose collaborative robot that carries a heavier load across a long reach, yet is designed to work beside people rather than behind a barrier.

Robots Europa, based in Dublin, supplies the GCR20-1400 to manufacturers, integrators and research facilities across the European Union and the DACH region. Robots Europa prepares each quotation, arranges delivery to the installation site and provides support for the robot after commissioning, so that a single point of contact handles the project from the first enquiry onwards.

Background

SIASUN and the GCR series

SIASUN is a Chinese manufacturer of robotics and automation equipment whose range spans industrial robots, mobile robots, logistics systems and collaborative arms. The GCR series is its line of collaborative robots, offered in several payload and reach classes so that a buyer can match the arm to the cell instead of designing the cell around the arm. Within that line, the GCR20-1400 is described by the manufacturer as a high-end, general-purpose model. The sources name two versions, the GCR20-1400 and the GCR20-1400-EX; the figures on this page are those published for the GCR20-1400.

Sensing, safety and ease of use

The robot integrates 2D/3D vision depth fusion together with highly sensitive force detection and control. In practice, this combination lets an application see where a part lies and feel how it is being handled, which matters for tasks such as fitting, insertion or surface finishing. Safety for human-robot collaboration rests on 16 TÜV-certified safety features. Programming is by drag-and-drop teaching, which lowers the threshold for operators who are not robot specialists. Scenario-specific software packages, support for multiple external interfaces, cloud-based monitoring of robot data and OTA remote updates complete the software side.

Technical Specifications

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

The manufacturer has not published the contents of the box, the controller dimensions, details of the teach pendant, the noise level, the service life or the software compatibility; these are confirmed at quotation.

What sets the GCR20-1400 apart from a lighter bench cobot?

The first difference is load. With a maximum payload of 20kg, the arm can carry an end effector and a substantial workpiece at the same time, whereas a smaller cobot often spends most of its capacity on the gripper alone. The second is reach: 1400mm lets one robot serve two machines, a conveyor and a pallet, or a wide fixture, without a linear axis beneath it. The third is that this capacity does not come at the expense of precision, since the published repeatability is ±0.05 mm.

What keeps the robot in the collaborative category is the safety concept rather than the size. The 16 TÜV-certified safety features are aimed squarely at human-robot collaboration, and the force sensing that supports them also serves the process itself, for example when a part has to be pressed home with a controlled force. The IP54/IP65 rating and an operating temperature range of -10°C-50°C mean the arm is not confined to a clean, climate-controlled hall.

How does the GCR20-1400 fit into an existing production line?

Integration starts at the tool flange, which follows GB/T 14468.1-50-4-M6 and corresponds to ISO 9409-1, so grippers and tools built to the ISO pattern can be fitted. Two digital I/O at the tool end, at 24V and 0.6A, allow simple grippers and sensors to be driven directly from the wrist. On the controller side, Tcp/Ip, Modbus/Tcp, Profinet and Ethernet/Ip cover the protocols most European lines already run, which makes it straightforward to connect the robot to an existing PLC.

Installation in any orientation gives designers freedom to mount the arm on the floor, on a wall or overhead, wherever it blocks the least space. The power supply accepts 220-240VAC at 10A or 100-200VAC at 16A, with a typical consumption of 600W. Once the robot is running, cloud-based data monitoring and OTA remote updates help maintenance teams follow its condition and keep the software current without a site visit for every release.

Who is the GCR20-1400 for?

The GCR20-1400 suits manufacturers who want to automate handling that is too heavy for a light cobot, yet who need people to keep working in the same area: machine shops loading CNC machines, electronics and appliance producers assembling larger housings, and packaging operations moving cases to the end of the line. System integrators will value the standard flange, the fieldbus support and the drag-and-drop teaching, which shorten commissioning and make hand-over to the customer's staff easier. Research institutes and training centres can use the vision and force capabilities as a platform for developing new applications.

Where a cell calls for a different combination of payload and reach, the other members of the range are worth comparing, such as the SIASUN Collaborative Robot (GCR25-1800) or the SIASUN Collaborative Robot (GCR16-2000); the full line-up is shown in the SIASUN GCR Series Cobots category. Buyers interested in the GCR20-1400-EX version should ask Robots Europa for its specification, as its distinguishing figures are confirmed at quotation.

What is the GCR20-1400 used for?

1. Machine tending — loading and unloading CNC machines, presses and injection moulding machines beside the operator.
2. Palletising and case handling — moving cartons and trays at the end of a packaging line.
3. Assembly — fitting, insertion and screwdriving where force control keeps each joint consistent.
4. Surface finishing — grinding, polishing and sanding with controlled contact force along the part.
5. Vision-guided picking — locating and picking parts from trays or bins using 2D/3D vision.
6. Inspection and testing — presenting parts to cameras or test stations with repeatable positioning.

Frequently Asked Questions

What payload and reach does the GCR20-1400 offer?

The robot has a maximum payload of 20kg and a reach of 1400mm, with six degrees of freedom.

Is the GCR20-1400 safe to work alongside people?

It is designed for human-robot collaboration and has 16 TÜV-certified safety features. A risk assessment of the complete application is still required before it enters service.

Which industrial networks does it support?

The published communication interfaces are Tcp/Ip, Modbus/Tcp, Profinet and Ethernet/Ip.

Can I use my existing grippers?

The tool flange follows GB/T 14468.1-50-4-M6, equivalent to ISO 9409-1, so tools built to that pattern can be mounted. Two digital I/O at 24V and 0.6A are available at the tool end.

Does programming require a robotics specialist?

No: the robot is programmed by drag-and-drop teaching, which is intended to make operation easier for staff without specialist training. Scenario-specific software packages are also available.

Can the robot be mounted on a wall or ceiling?

Yes, the manufacturer states that it can be installed in any orientation.

Where can I buy the SIASUN Collaborative Robot (GCR20-1400) and what does it cost?

Robots Europa supplies the GCR20-1400 across the EU and the DACH region. The cost depends on the version and configuration and is set out in a quotation, which you can request on this page.

Summary

The GCR20-1400 closes the gap between the cobot that is safe but light and the industrial arm that is strong but fenced off. It combines a 20kg payload and a 1400mm reach with ±0.05 mm repeatability, vision and force sensing, 16 TÜV-certified safety features and the interfaces a European line expects, all programmed by hand-guided teaching. Robots Europa quotes, delivers and supports the robot across the EU and the DACH region.
