Robotic Arm Kits

A robot arm kit ships as a complete set of parts that you assemble yourself using the included documentation and open-source guides. Star Arm 102 kits share the same 6+1 DoF design, 420mm reach, 12-bit encoders and LeRobot SDK support as the assembled units — the difference is whether it arrives ready to run or ready to build.

DIY Robot Arm Kit or Pre-Assembled Arm?

Whether you assemble it yourself or run it out of the box, a Star Arm 102 robot arm kit ships with every part included — brushless bus servos, structure, cables and fasteners — plus assembly documentation and the open-source LeRobot SDK.

What's Inside a Star Arm 102 Robot Arm Kit

Every kit contains the brushless bus servos, structural parts, cabling and fasteners you need, together with assembly documentation and links to the open-source LeRobot SDK. The LD kit includes 11 structural parts and 7 joint servos and assembles in about 1–2 hours using the printed brackets and the tools in the box.

• Brushless bus servos — matched to each configuration
• Structural parts — brackets and links for the arm assembly
• Cabling and fasteners — everything needed to complete the build
• Documentation — step-by-step assembly guide and the LeRobot SDK

Which Robot Arm Kit Fits Your Project

Robot arm kits come in leader and follower configurations. Leader arms are used for teaching, teleoperation and data collection; follower arms execute the motion a leader records. The LD and HD kits are leader arms, the FL kit is a follower, and the PiPER Mate kit is a compact leader arm. Every Star Arm 102 configuration shares the same 6+1 DoF architecture, 420mm reach and 12-bit encoders, so the choice comes down to control role and build time. Compare all Star Arm 102 options →
