SIASUN HC-X4-B (HC-X4-B)

Every handover costs time. A part leaves a machine, waits for a trolley, waits for an operator, and only then reaches the next station. On a busy floor, these small pauses often become the real bottleneck. The SIASUN HC-X4-B (HC-X4-B) shortens that chain by combining transport and handling in one machine. It is a SIASUN DUCO mobile collaborative robot in which a self-developed mobile platform and a collaborative robot work as a single unit. It travels to where the work is, positions itself, and then picks, places, assembles or inspects without a second system having to take over.

Robots Middle East sells the SIASUN HC-X4-B and supplies it to manufacturers, system integrators, research institutions and logistics operators across the Middle East. Our team prepares each quotation around the application you describe. We coordinate delivery to your site and remain your point of contact for support once the robot is in service.

Background

SIASUN and the DUCO mobile cobot family

The HC-X4-B belongs to the DUCO line of mobile collaborative robots from SIASUN. The defining idea of the line is integration. Rather than pairing an arm from one supplier with a vehicle from another, SIASUN builds the platform and the collaborative robot to function together, and the mobile platform is its own development. The family can be equipped with SIASUN's self-developed vision systems, grippers and other execution units. As a result, the same base machine can be configured for material handling, assembly, inspection or precision processing.

The manufacturer offers the family in several versions: the HC-X2-B, HC-X3-B, HC-X4-B, HC-X6-B, HC-X2-L and HC-X2-T. This page concerns the HC-X4-B alone, and every figure quoted here belongs to that version.

Where the HC-X4-B sits: mobility with precision

Mobile manipulators answer a familiar dilemma in automation. An autonomous mobile robot can move goods but cannot work on them. A fixed collaborative robot can work on parts but cannot leave its station. Combining the two creates a new demand: once the base has driven to a station, the arm must still find its target reliably.

The HC-X4-B has an overall accuracy of ±0.3mm. Navigation combines SLAM with QR code positioning. The robot runs on a wheel system designed specifically for the mobile collaborative robot, offering greater stability and reliability. An integrated teaching pendant brings the platform and the arm onto a single screen for visual interaction and debugging, which allows faster deployment.

Technical Specifications

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

SIASUN has not published several details for this version: the total weight, battery capacity, running time and charging time, the cobot arm model supplied, the IP rating, the noise level and what is in the box. Robots Middle East confirms each of these at quotation.

How does the HC-X4-B combine navigation with precise manipulation?

A mobile collaborative robot is only as useful as its arrival at each station. The HC-X4-B uses a combined SLAM and QR code navigation method.

In general terms, SLAM (simultaneous localisation and mapping) lets a vehicle build and update a map of its surroundings as it moves. This suits facilities where layouts change and routes need to be reconfigured. QR code markers provide fixed, unambiguous reference points on the floor, which helps at locations where repeatable positioning matters most. Using both gives a planner flexibility on open routes and firm references at the points where the arm has to work.

The figure that ties travel to task is the overall accuracy of ±0.3mm, which applies to the HC-X4-B as a whole rather than to the arm alone. For buyers planning assembly, inspection or precision processing, this is the specification to hold against the tolerances of the parts involved.

Commissioning also benefits from the integrated teaching pendant. Because the mobile platform and the collaborative arm are programmed and debugged from the same screen, engineers do not need to switch between separate interfaces. This single interface allows faster deployment.

How does the HC-X4-B keep people safe and keep working?

A robot that moves through shared space has to protect people at floor level and at the height where its arm works. The HC-X4-B offers ground and airspace safety with real-time protection, enabling safe human-robot collaboration. In practice, the robot can share aisles, cells and benches with staff rather than needing to be fenced off. Every installation should still be assessed against the specific site and task.

Continuity of work depends on energy. The HC-X4-B supports contact-based, wireless and automatic charging, and these methods support short-term, real-time and 24/7 operation. A site can therefore choose a charging strategy that fits its shift pattern, from opportunity charging between tasks to round-the-clock duty.

Who is the SIASUN HC-X4-B for?

The HC-X4-B is aimed at operations where the same robot must both move material and do something with it.

• Manufacturers of electronics, components and precision parts. They can use its overall accuracy and range of execution units for assembly and inspection at several workstations, rather than dedicating one cobot to each.
• Production engineers responsible for machine tending and intralogistics. Its 120kg Max platform load and compact 800*600*700mm vehicle dimensions suit shuttling work between machines.
• Research laboratories and universities. These users often value a single integrated platform for mobile manipulation, programmed from one pendant.
• System integrators across the region. They can build the HC-X4-B into larger cells, combining it with customer systems, vision and grippers.

The DUCO family also includes the SIASUN HC-X2-B (HC-X2-B), the SIASUN HC-X3-B (HC-X3-B), the SIASUN HC-X6-B (HC-X6-B), the SIASUN HC-X2-L (HC-X2-L) and the SIASUN HC-X2-T (HC-X2-T). Figures for those versions are not set out on this page. If your application sits close to the limits of the HC-X4-B's load or footprint, Robots Middle East will compare the versions against your requirements as part of the quotation.

What is the SIASUN HC-X4-B used for?

1. Material handling: collecting trays, parts and fixtures and delivering them between stations without a separate transport vehicle.
2. Machine loading: driving to machine tools or test rigs, then loading and unloading workpieces with the collaborative arm.
3. Assembly: carrying out assembly steps at several workstations with self-developed grippers and execution units.
4. Inspection: moving a vision system from point to point to check parts, products or equipment on the line.
5. Precision processing: performing fine operations at stations where the overall accuracy of ±0.3mm suits the tolerance.
6. Continuous intralogistics: running extended or 24/7 duty cycles supported by automatic, contact-based or wireless charging.

Summary

The pauses between machines, trolleys and operators are where much of a factory's time disappears. The SIASUN HC-X4-B closes those gaps by letting one integrated machine carry the work and perform it.

Its figures define the job it is built for: a 120kg Max platform load, ±0.3mm overall accuracy and SLAM & QR CODE navigation in an 800*600*700mm vehicle. It adds ground and airspace safety, a dedicated wheel system, a single teaching pendant for arm and platform, and flexible charging for round-the-clock duty.
