Cart (Without Casters)
Jig (Fixed Mount)ROBOTType 1: Jig Method
Transports by placing the cart onto a dedicated jig (mount)
Can be used even if the cart itself does not have casters (wheels).

A compact mobility module designed to overcome space constraints in tight manufacturing environments and ensure stable material transport.
Key Features
- Customized mount (jig) tailored to the specifications of the customer's LIFT cart
- VDA5050-based external system (WMS/MES) integration
- Up to 7 hours of continuous operation on a single charge
Payload Capacity125kg
Operating Time per Charge12 Hours
Under-cart Entry Width750 mm
Min. Aisle Width67 cm

Entry Width 750 mmEntry Height
550 mmROBOTType 2: Under-Lift (Direct Transport) Method
Without a jig, the robot drives underneath
the cart to lift and transport the cart directly
The cart must have casters (wheels), and sufficient clearance width
between the cart legs is required for the robot to enter.
Where It's Used
M2-LL shares the same driving unit, navigation, and safety systems already proven across manufacturing sites worldwide.
Factory Automation & Light-Load Transport
Automates manual material handling on shop floors that previously avoided automation due to space constraints and high cost.
Inter-Process Sample Transport
Specializes in safely transporting samples between material processing lines and quality inspection/analysis labs.
Small Parts Feeding to Assembly Lines
Receives parts handed off from large AGVs and distributes detailed parts to individual assembly line workers.
Narrow-Aisle Navigation, No Facility Changes
Navigates aisles as narrow as 67cm, so it can be deployed without modifying or removing existing factory infrastructure.
How to Connect & Get Started
Simple integration with your existing equipment and software
QR Marker Docking
Achieves docking precision under 10mm just by attaching a QR marker no complex custom software required.
E84 (PIO Sensor) Equipment Integration
A wireless PIO sensor compliant with the semiconductor industry's E84 standard senses equipment load status in real time for fully unmanned transport full integration takes an average of 2 days.
Buffer Station Integration
Dedicated buffer stations can be supplied together for smooth material charging and docking.
Nepler Web Control & Mobile App
Monitor robot routes and equipment status remotely via the Nepler dashboard, freely integrated and customized with your existing ERP, MES, and WMS. A dedicated tablet app also lets on-site workers create or edit maps directly.

Polaris3D Real Industrial Site and M2 Operation Video
M2 Platform Track Record
Korea — Gumi Plant
Following successful deployment at a leading Korean conglomerate's Gumi plant, the M2 platform now runs in stable shift-based operation across 9 global subsidiaries.
Rapid Large-Scale Deployment
At a 33,000 m² (10,000-pyeong) logistics facility, a 10-robot automation system was built in just 3 weeks, together with 100 matching buffer stations delivered simultaneously.
Hungary — SMD Process
Distributes small parts unloaded by large AGVs to workers across detailed sub-processes on the production line.
Indonesia — Mobile Phone SMD Process
Covers up to 200m round-trip distances to supply parts, eliminating wasted operator movement.
Brazil & Vietnam — SMD Manufacturing
Handles sample transport and inter-process material delivery smoothly even on highly variable, narrow-aisle production lines.
Built for Safety & Reliability
- Active obstacle-avoidance driving — automatically detects obstacles like people ahead and reroutes intelligently, unlike legacy AGVs that simply stop.
- Industrial safety certified — PL-B rated LiDAR and a 180° pressure-sensing bumper fully satisfy ISO 13849-1 machinery safety standards.
- Fire-safe, swappable LFP battery — a removable lithium iron phosphate battery removes fire/overheating risk and enables instant swaps for uninterrupted shift changes.
- Rugged sheet-metal housing — galvanized steel (EGI) housing withstands harsh factory conditions in a compact 310mm low-profile chassis.
- Certified reliability — fully passed ISO 9001, UN 38.3, IEC 62619, and EMS immunity testing.
