$6,500 assembled pair (WowRobo)WowRobo, an Enactic-certified manufacturer, sells a factory-assembled left and right arm system for $6,500, or $7,300 with a ZED top stereo camera (checked October 2026). Enactic gives the bill of materials as $6,500. RT Corporation sells assembled units in Japan by quote. The motorless OpenArm KER leader is $2,599 at WowRobo, and a 1.0-to-2.0 upgrade kit is $1,080.

Weeks+Shipping: ~4–6 wks (built to order). WowRobo builds each pair to order in Shenzhen with a 20–30 day lead time (Enactic's buying page says 20–40 days), then ships by DHL, UPS or FedEx. Its sample US rates are $480 express air with duties extra, or $800 with duties included. Fixed arms are exempt from the FCC's 2026 robot rule. WowRobo ↗

Remote control: Connects to a Linux PC with SocketCAN through a USB-to-CAN-FD adapter. The openarm_can library (C++, experimental Python) and the ROS 2 packages run there. macOS has no SocketCAN, so a Mac needs a separate Linux machine.

Overview

An open-source, human-scale pair of 7-DOF arms built for collecting teleoperation data and testing robot-learning policies. Two-way force feedback between a leader and a follower lets the operator feel contact, and 2.0 adds a compact gripper with a built-in camera. It suits labs that want an open alternative to ALOHA 2-style kits with a much higher payload. The catch is $6,500 for a built pair, a Linux CAN setup, no published repeatability, and a KER leader that Enactic still calls forthcoming.

Specifications

Category	Robot arms · Research & collaborative arms
Released	2026
Country	Japan
Availability	Available
DIY build plans	OpenArm · complete system $6,500 · difficulty 5/5
Programmability	Open source (hardware + software)
Built-in autonomy	None / scripted · Moves only when controlled, or plays preset motions
LLM support	Possible via SDK · No LLM tools from Enactic. Its tutorials train ACT imitation policies through LeRobot and serve them over a policy-server interface, and the C++/Python CAN library and ROS 2 packages could be driven by an LLM on the host PC. OpenArm docs (training) ↗
MuJoCo simulation	Official model · Enactic's openarm_mujoco ships a v2 bimanual MJCF (v2/openarm_bimanual.xml) plus the Cell, and openarm_mjlab adds mjlab integration. openarm_mujoco ↗
NVIDIA Isaac simulation	Official model · Isaac Lab ships openarm.py with one-arm and two-arm configs, and Enactic publishes RL tasks in openarm_isaac_lab. The Isaac model may be the 1.0 arm (unconfirmed). Isaac Lab openarm.py ↗
