What is OpenArm 2.0?
OpenArm is an open-source bimanual robot developed by Enactic, Inc. The official site is openarm.dev; Libertron builds, sells, further develops, upgrades, and supports it in Korea. 2.0 is the current generation: two 7-DOF arms, about 633 mm of reach, DAMIAO actuators, and CAN-FD / ROS 2 / Python control. It's used for teleoperation, imitation and reinforcement learning, manipulation research, data collection, and education. The earlier OpenArm 1.1 series is still offered, and both models ship with open CAD and BOM.

Frequently asked questions
How is OpenArm 1.1 different from 2.0?+
2.0 and the earlier generation (1.0 and 1.1) share the same arm structure, motors, and electronics. 2.0 changes the gripper to a compact one with an in-hand camera and replaceable fingers, swaps the J5 bracket, and adds KER and Cell to the lineup. 1.1 owners don't need a complete 2.0 unit: an upgrade kit converts the arm to the 2.0 gripper setup. Libertron plans to supply the upgrade kit starting in 2027. The 1.1 series is still available — see the OpenArm 1.1 page for its full spec and configurations.
What is KER?+
KER is the leader arm used for leader–follower teleoperation. You move KER by hand and OpenArm (the follower) mirrors it, recording the trajectory as training data. It's used for remote operation and demonstration-based data collection.
How much does OpenArm cost?+
Pricing is quoted per configuration. Add the arm, cameras, KER, and other options in the store and request a quote. Prices exclude shipping and taxes/duties; FedEx shipping is quoted with your order. Installation and demos are available in Korea.
How do you teach the robot?+
You're not locked into one teaching method. Use leader–follower teleoperation with KER, kinesthetic teaching by moving the arm by hand, or direct control through the ROS 2, Python, and CAN-FD APIs. From a first encounter with physical AI to full development, every option stays open.
Can it run a real production process?+
OpenArm is a platform for learning, teleoperation, and data collection. For work that needs validated process performance, we pair it with an RB20-class industrial arm so the platform matches the job.
How open is it?+
The CAD, BOM, and control software are public, so you can extend the hardware and integrate the software yourself.
