The Seeed Studio reBot Arm B601-RS Assembled Robotic Arm Kit & Gripper is a high-performance, open-source robotic arm platform designed for developers, researchers, educators and robotics enthusiasts exploring real-world robotic manipulation. With 6 degrees of freedom plus a gripper, a 754.7 mm working radius, 2.5 kg rated payload, and ±0.1 mm repeatability, it provides the precision and flexibility needed for a wide range of robotics experiments.
The B601-RS uses RobStride 00 and RobStride 06 motors with CAN Bus communication and operates from a 48V DC supply. Its pre-assembled configuration makes it easier to move from setup to programming and experimentation. One of its biggest advantages is the true open-source robotics ecosystem, with hardware blueprints, 3D-printable and machined-part files, detailed BOM documentation, Python SDK resources, and support for platforms such as ROS1/ROS2, MoveIt, LeRobot, Isaac Sim and Pinocchio.
Whether you are developing a robotic arm project, AI-powered manipulation system, physical AI application, robot control software or advanced STEM robotics setup, the reBot Arm B601-RS provides a flexible platform for moving from simulation and programming to real-world robotic applications.

Step-by-step lessons make robotics more accessible. With the reBot Arm B601-RS, you can rapidly and confidently transition from assembly to intelligent robot control.
Precision robotics for liquid handling, sample transfer, and laboratory processes. Designed for repeatability, delicacy, and quick experimentation.
Leading robotics frameworks such as LeRobot and Isaac Sim enable real-time control, data collecting, and simulation-to-real learning. A capable "hand" for embodied AI.
Precision is ±0.1 mm, with a payload capacity of up to 5 kg. The reBot Arm B601-RS allows for precise assembly, inspection, sorting, and material handling in industrial and warehouse applications. Compact and easily integrated into current production lines and workcells.
