Overview
Seven-axis force-controlled 'adaptive robot' arm from Flexiv (非夕科技), with a 4 kg payload, 876 mm reach, 20 kg arm weight and IP65 rating. Built-in force sensing gives 0.1 N force accuracy (0.03 N with the optional F/T sensor version), and the arm mounts at any angle. It is aimed at contact-rich work such as precision assembly, polishing and mobile workstations on AMR/AGV platforms, and is driven by the Hesper controller.
Will the Flexiv Rizon 4 do your task? Simulate it before you buy.
Four cobots on the same palletizing task, simulated before purchase.
We build your station in a simulator with the Flexiv Rizon 4 and one or two alternatives, and send you video plus cycle time, parts per shift, reach and payload check, and a payback estimate. Scoping is free, and every project is quoted individually.

| Contact | 2026-10-17 | Rizon 4 | Flexiv | No public price on the manufacturer page (contact / business inquiry only). A US reseller (roboticscenter.ai) lists one generic 'Flexiv Arms' product at US$55,000 without saying whether it is the Rizon 4 or Rizon 10, so it is not recorded as a Rizon 4 price. |

Key facts
- Rizon 4: 7 DoF, 4 kg payload, 20 kg, reach 876 mm, ISO 9283 repeatability +-0.05 mm, typical TCP speed 1.0 m/s, IP65, 0 to 45 C, 20-80% humidity non-condensing, noise under 70 dB. Source: flexiv.com/product/rizon, fetched 2026-10-17.
- Rizon 4 + F/T Sensor: 21 kg, reach 919 mm, force accuracy 0.03 N, max TCP force 150 N. Same page. The standard Rizon 4 has 0.1 N accuracy and 200 N max TCP force.
- Hesper controller: 12 kg, 500 W, 16 digital inputs and 16 digital outputs, Profinet and Modbus TCP/IP, IP20.
- Sibling models on the same page: Rizon 10 (10 kg, 38 kg, 941 mm). Rizon 4s (more advanced built-in sensors than Rizon 4) was introduced in Nov 2020 per Flexiv's own news release but is not on the current product page.
- Launch year of the Rizon 4 is not stated on the fetched official pages. Chinese press (jiemian.com) dates the first Rizon (拂晓) release to April 2019. year_available is left null.
- Software: Flexiv publishes the Robotic Development Kit (RDK) on GitHub, 'Supports C++ and Python. Compatible with Linux, macOS, Windows, and QNX' (github.com/flexivrobotics/flexiv_rdk), and a ROS 2 integration of the RDK (github.com/flexivrobotics/flexiv_ros2), both fetched 2026-10-17. The product page itself does not list them; joint limits are not on it either. open_source stays false because it refers to the robot software, which is not stated open.
