reBot-DevArm: open-source Robotic Arm

🚀 100% Open Source · Embodied AI · Full Hardware + Software Stack

📦 Build your own robotic arm · 🧠 Learn robotics · 🏭 Deploy real applications

reBot-DevArm (reBot Arm B601 DM and reBot Arm B601 RS) is a robotic arm project dedicated to lowering the barrier to learning Embodied AI. We focus on "True Open Source" — not just the code, we unreservedly open source everything:

• 🦾 Two versions of the robotic arm: We will provide all open-source files for two versions of the robotic arm with the same appearance: Robostride and Damiao.

• 🛠️ Hardware Blueprints: Source files for sheet metal parts and 3D printed parts.

• 🔩 BOM List: Detailed down to the specifications and purchase links for every single screw.

• 💻 Software & Algorithms: Python SDK, ROS1/2, Isaac Sim, LeRobot, etc.

• We offer five kit options at Seeedstudio.com:

  • Arm Body Motor Kit: Includes only motors and wiring harnesses for the robotic arm.
  • Arm Body Structural Kit: Includes only mechanical structural components.
  • Gripper Complete Kit: Includes motors, wiring harnesses and structural components for the gripper.
  • Full Kit: Includes the complete set of the robotic arm body and gripper.
  • Pre‑assembled Robotic Arm: Fully assembled finished robotic arm.
