== Technical overview ==
* LeRobot is a robot development framework by Hugging Face that provides models, datasets, and toolchains under the PyTorch ecosystem for real-world robotics tasks.
* It supports imitation learning and reinforcement learning using algorithms such as ACT and Diffusion Policy.
* The system enables data collection, model training, and autonomous capture via the “manual leader arm + automatic follower arm” configuration.
* SO-ARM100 uses bus servos at 7.4 V with a stall torque of 19.5 kg·cm; suitable for teaching with lower load.
* SO-ARM101 uses bus servos at 12 V with a stall torque of 30 kg·cm; suitable for higher-load applications.
* The SO-ARM100 series offers four package options: no 3D-printed parts, with 3D-printed parts, camera kit, and Jetson Orin Nano kit.
* The SO-ARM101 series offers five package options: no 3D-printed parts (SE), with 3D-printed parts, with 3D-printed parts (SE), camera kit (SE), and Jetson Orin Nano kit (SE).
* Both series provide STEP models for 3D-printing the mechanical components.

== Notes and version constraints ==
* More detailed installation, calibration, or remote-control steps are not included in this source; they are found in separate tutorials (e.g., setting up the LeRobot environment, setting servo IDs, assembly, calibration, dataset recording).
* Package labels such as “(SE)” may indicate regional or distribution variants; their exact meaning should be clarified before purchase.
* The voltage values (7.4 V vs. 12 V) apply to the respective servo configurations; the actual power supply must be selected accordingly.
* Before operation, all 3D-printed parts should be checked for fit and the servo IDs must be set correctly.
