Cobot Series
Collaborative robotics. Built by Han’s.
Robotics for the Real Factory.
Twenty years of motor and motion-control engineering applied to the next generation of factory automation.
A Family of Arms. One Engineering Standard.
The Cobot Series isn’t one robot. It’s five product families, each engineered for a specific class of work—but all built on the same self-developed motors, drives, encoders, and force sensors. The result is consistency: choose the arm that fits the job, and get the same precision, the same reliability, the same software, and the same integration logic.
Elfin Series. The Workhorse.
Six-axis collaborative arms with payloads from 3kg to 15kg and reach up to 1800mm. Dual-joint module design improves reach flexibility in confined spaces, allowing operation around obstacles in compact production layouts. Used for assembly, picking, welding, grinding, spraying and line tending.
Elfin-Pro. AI Built In.
The arm sees what it's working on, recognises parts, reads QR codes, and adjusts pressure as it moves — no third-party cameras or sensors to integrate. The thinking version of the working arm.
Elfin-Ex. Built for Hazardous Work.
National explosion-proof certification. Leak-compensated positive-pressure architecture. IP66 sealing. Designed for petrochemical, painting, and any environment where combustible gases or dust make conventional automation a non-starter. The robot that goes where humans shouldn’t.
S Heavy Payload Series. Lifting at Scale.
Payloads from 20kg to 50kg. Reach to 2000mm. Built for machine loading, palletising, and heavy assembly work that smaller cobots can’t touch. Advanced vibration-suppression algorithms keep the arm smooth at full load and full speed—where the operational economics actually matter.
Plug, Play, and Build.
A complete partner ecosystem of grippers, vision systems and force sensors—including Robotiq, OnRobot, Schunk, SMC, Cognex, Keyence, Mech-Mind and ATI—integrates via standard IO and communication interfaces. Supports loading, assembly, testing, screw-driving, gluing, grinding and spraying on a single robotic platform.
Unrivalled Results.
