Seeed Studio reBot Arm B601-DM Body Motor Kit is the official body motor kit for the Seeed Studio reBot Arm B601-DM open-source robotic arm platform. This Seeed Studio motor kit is intended for developers who want the official drive system of the reBot Arm B601-DM while keeping flexibility over the structural parts, mechanical design, and custom robotic arm integration. If you also need the matching mechanical frame, see the reBot Arm B601-DM Body Structure Kit.
According to the official Seeed documentation, the reBot Arm B601-DM Body Motor Kit includes only the motors and wiring harnesses needed for the robotic arm. This makes it a practical choice for developers machining their own structural parts, reproducing the official arm with open-source files, or building a custom robotic arm around the official Damiao motor system.

Hardware Overview
Other Content
Built for custom structure development
The Seeed Studio reBot Arm B601-DM Body Motor Kit is intended for users who do not need the full assembled robotic arm and instead want the official body motor kit to pair with their own structural parts. This is particularly useful for custom mechanical layouts, experimental robotic arm builds, and engineering projects that require more flexibility than a fixed assembled kit.
Open-source robotics ecosystem
The wider Seeed Studio reBot Arm B601-DM ecosystem is built around true open source. Hardware blueprints, BOM files, Python SDK support, and compatibility with LeRobot, ROS, Pinocchio, and Isaac Sim make this motor kit relevant for both mechanical assembly and embodied AI development.
Modular purchasing structure
The reBot Arm B601-DM family is intentionally modular. Developers can choose the Body Motor Kit , Body Structure Kit , Gripper Kit , or a complete assembled version depending on how much of the mechanical build they want to control themselves.
