Star Arm 102 FAQ
Answers about model selection, teleoperation, software and robot development.
What is the Star Arm 102?
Star Arm 102 is an open-source 6+1 DoF robot arm platform for teleoperation, teaching, robotics development and embodied AI. The series includes LD and HD Leader arms for motion input and the FL Follower arm for task execution.
Which Star Arm 102 model should I choose?
Choose the lightweight LD Leader for teaching and rapid data collection, the HD Leader for stable hover positioning and precise demonstrations, or the FL Follower for robotic manipulation, automation and physical AI deployment.
Can Star Arm 102 be used for teleoperation and data collection?
Yes. Pair an LD or HD Leader with an FL Follower for real-time master-slave teleoperation, trajectory recording and imitation-learning dataset collection. A Leader arm can also record demonstrations independently.
Which SDKs and robot development tools are supported?
Star Arm 102 supports browser-based control, the Python SDK, ROS2 Humble and LeRobot. The FL Follower also supports MoveIt2 motion planning and Gazebo simulation for robot development and testing.
Is Star Arm 102 compatible with LeRobot?
Yes. LD and HD can operate as LeRobot teleoperators, while FL serves as the execution robot. The workflow covers teleoperation, dataset collection, model training and deployment to the physical arm.
Are CAD files, 3D models and assembly resources available?
Yes. Star Arm 102 provides CAD drawings, STEP files, 3D-printable models, BOM information, assembly guidance, software examples and troubleshooting documentation for ready-built or self-assembled projects.
