reBot-DevArm: An Open-Source Robotic Arm

reBot-DevArm is an open-source robotic arm project aimed at lowering the barrier to Embodied AI learning. It aims to open not just code but hardware, structural parts, BOM, and the software stack as well.

The scope of the release is as follows.

• Two versions: the Robostride and Damiao versions, which share the same exterior
• Hardware blueprints: source files for sheet-metal parts and 3D-printed parts
• BOM: a detailed list including screw specifications and purchase links
• Software/algorithms: Python SDK, ROS1/2, Isaac Sim, LeRobot, and more

Purchase options are also presented. On Seeedstudio, you can choose from the Arm Body Motor Kit, Arm Body Structural Kit, Gripper Complete Kit, Full Kit, and Pre-assembled Robotic Arm, and a Leader Arm is also sold separately.

The roadmap discloses support status separately for the reBot Arm B601 DM and B601 RS.

• B601 DM: Basic motor control, new STEP structural files and BOM, performance testing, assembly video, Pinocchio, and LeRobot are complete
• B601 DM: ROS2 (Humble) and Isaac Sim are in progress, scheduled for 2026.04.20
• B601 RS: Basic motor use is complete; the remaining structural files/BOM, assembly video, ROS2, LeRobot, Pinocchio, and Isaac Sim are targeted for 2026.05

The project also states that it aims to be more than just a product—it aspires to be a learning community. It says it will provide free tutorials for a full-stack robotics ecosystem connecting edge computing boards such as Jetson, Raspberry Pi, and XIAO with sensors, motors, and servos.
