OYMOTION

OpenArm

Embodied dual-arm robot with Dexterous Robotic Hand

A dual-arm platform for teleoperation, motion data collection and embodied AI research, combining 7-DoF arms with dexterous hands and force feedback.

Description:

The OYMotion Embodiod Dual-Arm Robot is a dedicated sottwaro-hardwaro system built on the OpenArm open-source master-slave dual-arm robot tor action data acquisitiom Featuring dual 7-DOF humanoid arms With quasi-direct drive motors and master-slavo bidirectional torco toodback, it captures real-time, high-precision full-dimensional motion and torce data trom human upper limbs and hands, enabling accurate motion mapping and standardized data aggregation.

36 DoF — Degree of Freedom

660 mm — Arm Reach

6 kg — Peak payload per arm

7 kg — Weight per arm
