reBot Arm B601-DM Body Structure Kit

Seeed reBot Arm B601-DM Body Structure Kit

The reBot Arm B601-DM Body Structure Kit is the mechanical parts kit for the 6-DoF open-source robotic arm reBot Arm B601-DM by Seeed Studio - without gripper and without motors. It is intended for users who already own a matching set of DAMIAO motors (3 × 4310 and 3 × 4340P) and the corresponding control electronics, or who source them separately, and who want to assemble the arm themselves following the official documentation.

The reBot Arm B601 is a fully open-source project: hardware blueprints, sheet-metal and 3D-print source files, BOM down to the screw level, plus Python SDK and integrations for ROS 1/2, MoveIt, Pinocchio, Hugging Face LeRobot and NVIDIA Isaac Sim are freely available under Creative Commons (CC BY-NC-SA 4.0). The platform targets embodied AI research, teleoperation, imitation learning and reinforcement learning.

The main structure is CNC-machined from 5052 aluminium, while non-load-bearing and cosmetic components are produced in ABS and PLA via 3D printing. Compared to the raw GitHub BOM, the official Seeed kit includes several premium upgrades: laser-engraved anti-error markings, high-quality braided wiring harnesses, and several load-bearing brackets replaced by machined metal parts instead of 3D prints.

Note: This kit contains only the mechanical parts of the arm body. Motors, USB-CAN driver board, power board, XT30 cables and gripper are not included and must be obtained separately as the Body Motor Kit and Gripper Kit, or supplied by the user.
