SEER Robotics SPK-M50J-ZQ (SPK-M50J-ZQ)

Most warehouse robots carry a load from one place to another and then wait for a person to unload it. The SEER Robotics SPK-M50J-ZQ (SPK-M50J-ZQ) takes a different view of the job: it drives to the shelf, grabs the bin with its own gripper, and stacks it on a multi-layer tray on its back. The walking and the handling belong to one machine.

The product is available through this page, by quotation.

Background

SEER Robotics and the carton transfer line

SEER Robotics builds autonomous mobile robots for factories, warehouses and logistics centers. Its range spans very different machines, from counterbalanced forklifts and pallet trucks to smaller robots for bins and cartons. The SPK-M50J-ZQ belongs to the SEER CartonTransfer Robot series, the part of the range aimed at moving cartons and material bins rather than whole pallets.

The idea behind this family is simple. In many facilities the heavy pallet flow is already organized, but the last stretch, where individual bins are pulled from racks and delivered to stations, still depends on people walking long distances with carts. A robot that can both travel and pick takes that walking out of the day.

Positioning and key technology

The SPK-M50J-ZQ is a Laser SLAM Multi-layer Carton Transfer Autonomous Robot. Its navigation type is Laser SLAM combined with QR code navigation, and the robot supports four navigation methods in all: SLAM, QR code, reflector and NFL. That gives a project team a choice of how to guide the robot through a building, instead of forcing one method on every site.

Picking is done by grabbing with a gripper, with 2D vision correction. The vision step matters because bins are never placed on a shelf in exactly the same spot twice; the camera corrects the gripper before it closes. Behind it all sits the SRC controller, which brings walking and goods pick-and-place together in one unified control system, so the driving and the handling are not two separate programs to be coordinated.

How does the SPK-M50J-ZQ pick and carry bins?

The working cycle starts with navigation. The robot localizes itself with its laser SLAM, with QR codes where a site uses them, and it can also work with reflectors or NFL. Position accuracy is ±5 mm and angle accuracy is ±0.5°, which is the precision needed to line up a gripper with a bin on a rack.

At the shelf, the gripper grabs the bin and 2D vision corrects its position. The robot then places the bin on one of the layers of its back tray. The tray has 3 to 6 layers, so one trip can collect several bins instead of one. A single bin may weigh up to 50 kg, and the robot as a whole may carry up to 300 kg. The listed bin sizes are 400 x 300 x 280 mm, 600 x 400 x 280 mm and 800 x 600 x 280 mm, so the common sizes of plastic totes in a warehouse are covered by the list.

Travel speed is up to 1.5 m/s, and the maximum lifting speed is 0.6 m/s. Since the controller handles both walking and pick-and-place, the robot can plan its movement and its handling together.

What does the robot need from the building?

Space and environment are the first questions on any site visit. The robot comes with two sets of outer dimensions, 1700 x 1000 mm and 2000 x 1200 mm, and two minimum aisle widths, 1110 mm and 1310 mm. Your layout should be checked against both sets of figures.

The robot weighs 500 kg with its battery. The operating range is 0°C to 45°C with relative humidity from 10% to 90%, without compression and without condensation. That suits indoor spaces such as distribution rooms and production halls.

For safety, the robot has built-in front and rear dual laser radars, safety edge sensors and hardware self-checks. It carries one H1 and one C2 lidar. The 48 V / 46 Ah lithium iron phosphate battery gives a comprehensive battery life of at least 8 hours, and charging from 10% to 80% takes no more than 1.5 hours, so a shift pattern with short charging stops is realistic.

Who is the SPK-M50J-ZQ for?

The robot suits operators of bin-based storage: e-commerce and retail distribution centers, spare parts stores, component warehouses next to production lines, and third-party logistics providers who pick from racks into totes. It is most useful where people spend much of their shift walking between shelves and stations rather than handling goods.

It also suits manufacturers who feed lines with bins from a central store and want that run automated without rebuilding the building. Because it supports four navigation methods, it can fit both modern sites and older ones where reflectors or QR codes are already in place.

If your goods move on pallets rather than in bins, a different machine will serve you better; see the SEER Robotics 3 Ton Autonomous Pallet Truck (SFL-CBD30) or the SEER Robotics 2000 Kg Counterbalanced Autonomous Forklift (SFL-CPD20-Y).

What is the SPK-M50J-ZQ used for?

1. Rack-to-station bin delivery: the robot collects bins from storage racks and brings them to packing or workstations.
2. Multi-bin collection runs: the layers of the back tray let one trip carry several bins at once.
3. Line-side replenishment: bins of components are moved from the store to production lines on a repeatable route.
4. Returns and sorting flows: bins are shuttled between receiving, inspection and put-away areas.
5. Narrow-aisle bin handling: the stated minimum aisle widths allow work between racks where space is limited.
6. Extended shift operation: a battery life of at least 8 hours and quick charging keep the robot working through a shift.

It supports four: SLAM, QR code, reflector and NFL. Its navigation type is listed as Laser SLAM+QR code navigation.

How many bins can it carry at once?

The back tray has 3 to 6 layers. The maximum load is 50 kg per material bin and 300 kg for the robot.

Which bin sizes does it handle?

The suitable bin dimensions are 400 x 300 x 280 mm, 600 x 400 x 280 mm and 800 x 600 x 280 mm.

How does the robot pick a bin?

It grabs the bin with a gripper, and 2D vision corrects the position before the grab.

How long does the battery last, and how fast does it charge?

The comprehensive battery life is at least 8 hours. Charging from 10% to 80% takes no more than 1.5 hours.

What operating temperature and humidity does it allow?

Where can I buy the SPK-M50J-ZQ and what does it cost?

You can request it through this page, by quotation. The cost depends on your project and is given in the offer, not printed here.

Summary

The SPK-M50J-ZQ answers a simple question: why should a robot only carry when it can also pick? With laser SLAM and QR code navigation, a gripper with 2D vision correction, a back tray of 3 to 6 layers and an SRC controller that unifies driving and handling, it takes the walking out of bin work. If that matches your warehouse or production line, this page is the starting point.
