Introducing OpenArm 2.0: A Versatile Open-Source 7-DOF Robot Arm

OpenArm 2.0 Overview

Developed by Tokyo-based Enactic, the OpenArm 2.0 is a cutting-edge open-source robot arm featuring seven degrees of freedom (7-DOF). This robotic arm is specifically designed to facilitate physical AI research, teleoperation, and extensive data collection in contact-rich environments.

Key Features

Equipped with quasi-direct-drive (QDD) backdrivable joints, the OpenArm 2.0 supports compliant motion and bilateral force-feedback control. It can handle a nominal payload of 4.1 kg and a peak payload of 6 kg, making it suitable for a variety of applications. The arm also boasts a compact parallel gripper that includes an in-hand camera and interchangeable fingers, enhancing its versatility.

Applications and Ecosystem

The OpenArm ecosystem features the OpenArm Cell for standardized evaluations and the OpenArm KER, a motorless replica for data collection and teleoperation. With support for open-source CAD, firmware, and various robotic software tools, this platform is ideal for applications ranging from imitation learning to robotic manipulation.
