SIASUN P-T1500D (P-T1500D)

Every intralogistics plan eventually meets the same trade-off. A conveyor never strays from its line, but it cannot follow the layout when the layout changes; a forklift can go almost anywhere, but only with a trained driver at the wheel and an aisle wide enough to turn in. The SIASUN P-T1500D (P-T1500D) sits between those two answers: a low, flat mobile robot that drives beneath a rack or cart, raises it clear of the floor and delivers it along routes that are redrawn in software rather than rebuilt in steel. For operations that want the discipline of a fixed line together with the freedom of a vehicle, it offers a practical way to close the gap.

Robots Middle East supplies the SIASUN P-T1500D to manufacturers, warehouse operators and logistics providers across the Middle East, from production plants in established industrial cities to distribution centres in the region's free zones. Robots Middle East prepares the quotation, coordinates delivery to site and remains the point of contact for technical support once the robot is in service, so that a single partner answers for the project from the first enquiry to daily operation.

Background

SIASUN and its robotics lineage

SIASUN Robot & Automation is a Chinese robotics manufacturer based in Shenyang, with roots in the Shenyang Institute of Automation of the Chinese Academy of Sciences. Over the years the company has built a broad portfolio that spans industrial robot arms, cleanroom handling systems and mobile robots for factories and warehouses. That background in production automation shapes its mobile robots: they are designed to fit into manufacturing processes rather than to stand apart from them, and they are supported by fleet software intended to coordinate many machines at once.

An under-ride lift robot within a five-model series

The P-T1500D belongs to SIASUN's family of Under-ride Lift Mobile Robots, a series that the manufacturer names in five versions: P-T600D, P-T1000D, P-T1500D, P-T2000D and P-T3000D. The principle is common to the class. Instead of forks or a top-mounted conveyor, the robot carries its load on a lifting platform built into a low chassis. It drives underneath a rack, trolley or shelf unit, lifts it a short distance, transports it and sets it down again at the destination. Because the robot travels beneath the load rather than beside it, the footprint of the transport task is essentially the footprint of the load itself, which suits dense layouts where aisle space is valuable.

How do SLAM and QR Code navigation work together on the P-T1500D?

The P-T1500D is offered with two navigation methods: SLAM combined with QR Code, or QR Code alone. In general terms, SLAM (simultaneous localisation and mapping) allows a mobile robot to build a map of its surroundings and locate itself within that map as it moves, so routes can be laid out without physical guide lines. QR Code navigation relies on coded markers fixed to the floor; each marker gives the robot an exact reference point as it passes over it.

Combining the two gives a site a choice. Where the floor plan changes often, or where marker installation across a large area is impractical, SLAM supports flexible routing, while QR Codes at pick-up and drop-off points anchor the robot precisely where precision matters most. Where the layout is stable and highly repetitive, a QR Code grid on its own offers a simple, predictable arrangement. Either way, the positioning accuracy of ± 10 mm/±1° is what makes the handover reliable: a rack set down within that tolerance lines up with racking, workstations or the next robot in the chain without an operator nudging it into place.

What does the IMRS 2.0 platform add to a fleet?

A single robot moving a single rack is useful; a coordinated fleet is where the economics of automation usually emerge. SIASUN supports its solutions with the IMRS 2.0 platform, which provides multi-robot dispatching, route optimisation, data analytics and digital twins. Dispatching assigns tasks to the most suitable robot, route optimisation keeps traffic flowing as the number of vehicles grows, and analytics give operations managers a view of utilisation and throughput. The digital twin capability allows a site to model and review its logistics flows virtually, which is valuable both when planning a new layout and when adjusting an existing one. For buyers, this means the P-T1500D can be specified as one element of a wider system rather than as a stand-alone machine, and that robots from the same series can share one control layer as requirements evolve.

Who is the SIASUN P-T1500D for?

The robot speaks first to manufacturers who replenish production lines from a central store and want that flow to run on schedule without tying up staff or forklifts. Automotive suppliers, electronics assemblers and producers of consumer goods often move the same racks and carts between the same points many times per shift, which is exactly the repetitive pattern that under-ride robots handle well.

Warehouse operators and third-party logistics providers form a second group, particularly those running shelf-to-person picking or moving trolleys between receiving, storage and dispatch. In the Middle East, where new distribution centres are frequently designed around automation from the outset, a low-profile robot with a fleet platform fits naturally into greenfield planning as well as into retrofits of existing sites.

Not every load profile calls for the same version. Buyers whose racks and carts are lighter may find the SIASUN P-T600D (P-T600D) or the SIASUN P-T1000D (P-T1000D) a closer match, while operations moving heavier units should compare the SIASUN 2000 Kg Under-ride Lift Mobile Robot (P-T2000D) and the SIASUN P-T3000D (P-T3000D). Robots Middle East helps match the version to the actual loads on site as part of the quotation.

What is the SIASUN P-T1500D used for?

1. Line-side replenishment: carrying racks of components from the store to assembly cells on a fixed rhythm.
2. Goods-in transfers: moving incoming carts from receiving docks to storage or inspection areas.
3. Work-in-progress buffering: shuttling partly finished goods between process stages and buffer zones.
4. Dispatch staging: bringing finished goods on trolleys or shelf units to the outbound area ahead of loading.
5. Shelf-to-person picking: delivering storage shelves to picking stations so staff stay at their workplace.
6. Coordinated fleet operations: running several robots under IMRS 2.0 dispatching across a shared site.

Pricing and Availability

The SIASUN P-T1500D is supplied on a quotation basis, because the final configuration depends on the navigation method chosen, the number of robots, the fleet software scope and the conditions on site. Robots Middle East reviews your loads, layout and throughput targets and prepares an offer for the configuration that fits them. Delivery, customs clearance and after-sales support are arranged together with the quotation. To begin, the quotation request for the SIASUN P-T1500D (P-T1500D) is available on this page.

Frequently Asked Questions

What navigation does the SIASUN P-T1500D use?

The robot is offered with SLAM combined with QR Code, or with QR Code navigation alone. The choice depends on how often the layout changes and how the site prefers to mark its routes.

How precisely does it position at a pick-up or drop-off point?

The positioning accuracy is ± 10 mm/±1°. That tolerance allows racks and carts to be set down where workstations and storage positions expect them.

What is the rated operating time?

The rated operating time is 6–8 hours. Robots Middle East can advise on charging arrangements for multi-shift operation as part of the project.

How high does the P-T1500D lift its load?

The lifting height is 60 mm, enough to raise a rack or cart clear of the floor for transport. The overall dimensions are 1200/820/280 mm.

Can several P-T1500D robots work together?

Yes. The IMRS 2.0 platform provides multi-robot dispatching, route optimisation, data analytics and digital twins, so a fleet can be coordinated from one control layer.

Which version of the series suits my loads?

SIASUN offers the series as P-T600D, P-T1000D, P-T1500D, P-T2000D and P-T3000D. Robots Middle East reviews the racks and carts you move and recommends the version that fits them.

Where can I buy the SIASUN P-T1500D (P-T1500D) and what does it cost?

Robots Middle East supplies the SIASUN P-T1500D across the Middle East. The cost depends on configuration, fleet size and project scope, so it is provided in a tailored quotation requested from this page.

Summary

The SIASUN P-T1500D answers the old choice between rigid conveyors and driver-dependent forklifts with a third option: a low robot that travels beneath its load, positions it to ± 10 mm/±1°, lifts it 60 mm and runs for a rated 6–8 hours, while the IMRS 2.0 platform turns individual machines into a coordinated fleet. Its SLAM + QR Code or QR Code navigation lets routes follow the process rather than dictate it, and the wider series means the right version can be matched to the loads actually moved on site. For manufacturers and logistics operators across the Middle East who want material to flow on schedule without fixed infrastructure, and who want Robots Middle East to handle quotation, delivery and support, this page is the starting point.
