The highest-DOF option in the Robot Arms & Manipulators family is the ROBOTIS AI Worker FFW-SG2, with 25 degrees of freedom — a semi-humanoid mobile manipulator with dual 7-DOF arms on a swerve-drive base, built around DYNAMIXEL actuators and an onboard NVIDIA Jetson AGX Orin 32GB . Note that 6 of the 18 products in this family have no DOF value listed in the catalog, so the ranking covers the 12 that do . robotis.com +2robotis.com ↗“robot.degrees_of_freedom=25”robotis.com ↗“dual 7-DOF arms on a swerve-drive mobile base”robotis.com ↗“12 of 18 products in scope have a value”

A few considerations for your use case:
- If you need mobile bimanual manipulation, the FFW-SG2 (25 DOF) and TIAGo Pro (23 DOF) both pair dual 7-DOF arms with an omnidirectional base; the FFW-SG2 has the higher DOF count and the higher payload (6 kg vs 3 kg) . robotis.com +1robotis.com ↗“robot.payload_kg=6 kg”pal-robotics.com ↗“robot.payload_kg=3 kg”
- For a stationary dual-arm bench setup, the FFW-BG2 (19 DOF) offers the same dual 7-DOF arm configuration without the mobile base.
- For low-cost imitation-learning / LeRobot workflows, the Waveshare RoArm-M3 kits are leader-follower 5+1 DOF dual-arm kits with Hugging Face LeRobot support — far fewer DOF (6 total) but purpose-built for bimanual data collection; they can be bundled with a Jetson Orin Nano Super or Orin NX Super board as the main controller . waveshare... +1waveshare.com ↗“Leader-follower 5+1 DOF dual robotic arm kit from Waveshare supporting Hugging Face LeRobot”waveshare.com ↗“robot.degrees_of_freedom=6”
If a mobile, high-DOF dual-arm platform is the priority, the ROBOTIS AI Worker FFW-SG2 is the top pick; if a longer reach (2,360 mm) and a lifting torso matter more, the TIAGo Pro is the close second.
