📖 Introduction

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.

Build Your Own reBot Arm

  • We offer five kit options:
    • 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.

You may purchase the remaining parts from the SeeedStudio Store based on the components you already have (expected availability: April 15, 2026).

You can leave your information here, and we will send you the limited pre-order link in advance.
