KUKA LBR iisy 3

Our Verdict: German engineering meets collaborative simplicity. The torque sensing and iiQKA OS make it a joy to work with.

The KUKA LBR iisy 3 is a sensitive collaborative robot engineered in Germany with integrated torque sensors for gentle, force-controlled tasks. KUKA’s “iisy” philosophy means ease of use, and it delivers with a hand-guided teaching mode and intuitive iiQKA operating system.

The iisy 3’s torque sensing enables applications requiring precise force control, such as polishing, inserting flexible parts, and contact-based quality testing. Its compact footprint and low weight make it easy to deploy and redeploy as production needs change, ideal for high-mix, low-volume manufacturing.
