Star Arm 102 Assembly Guide

Note

The assembly instructions in the GitHub repository are still being improved. This page first collects the pre-assembly preparations, resource links, and general checks so they can be used before the complete illustrated assembly guide is released.

Assembly Resources

• GitHub Hardware Directory: view the parts list, CAD directory, and source files for assembly materials.
• Local Drawings and Model Downloads: view the PDF, DWG, and MakerWorld model entries organized in this wiki.
• MakerWorld Model Page: obtain 3D printing model resources.

Before Assembly

Hardware and Parts

• Confirm that the number of 3D-printed structural parts is complete and that there are no obvious cracks, warping, or blocked holes.
• Confirm that the servo models match their joint positions. The LD and FL models use different servo configurations, so use Product Specifications as the reference.
• Confirm that accessories such as the UC-01, servo cables, power adapter cable, USB-A to USB-C cable, screw kit, woodworking clamps, and threadlocker are complete.
• Confirm that the power supply specification matches the model: LD can use 12V2A / XT30, and FL can use 12V10A / XT30.

Recommended Tools

• Phillips screwdriver and hex keys.
• Tweezers or needle-nose pliers for arranging cables and fixing small screws.
• Woodworking clamps for helping secure the base or structural parts.
• A small amount of threadlocker for positions that need anti-loosening treatment.

Assembly Checks

1. Install the structural parts in the order of the robotic arm joints, and avoid reversing left/right or front/back directions.
2. Leave enough cable slack for joint movement, and avoid tension or pinching at the limit angles.
3. Before fixing each servo, confirm its ID, model, and installation direction to reduce rework.
4. Before powering on, gently rotate the joints by hand to check for obvious interference, binding, or cable pulling.
5. After the first power-on, run low-speed, small-angle tests first. Do not directly run large-range trajectories.

Follow-Up Configuration

• Use Python SDK to verify Leader and Follower serial port recognition and basic teleoperation.
• Use ROS2 to verify MoveIt2, Gazebo, the real robotic arm driver, and teaching trajectories.
• If connection or motion issues occur, check FAQ first.
