Flexiv · Industrial · 2019
The Flexiv Rizon 4 is the world's first adaptive robot — unveiled at Hannover Messe in April 2019 — and the founding model of Flexiv's Rizon series. Unlike position-controlled cobots, the Rizon 4 is built around force control: torque sensors in all seven axes give it whole-body force sensitivity (0.1 N sensing accuracy, up to 200 N TCP force), letting it perform contact-rich tasks like polishing, insertion and assembly while tolerating positional uncertainty that would defeat conventional arms. Its human-arm-inspired 7-DoF kinematics (4 kg payload, 876 mm reach, ±0.05 mm ISO 9283 repeatability, 20 kg mass) keep an optimised force-control posture through the workspace, and the IP65 body mounts at any angle including on AMR/AGV platforms. Built to ISO 13849 PL=d with dual-channel redundancy and CE & ETL certified, it runs from the compact Hesper controller and is programmed via Flexiv Elements drag-and-drop primitives or the C++/Python RDK. Founded by Stanford robotics researchers, Flexiv positioned the Rizon 4 as a third robot category beyond industrial and collaborative arms.
