The Seeed Studio SO-ARM100 Low-Cost AI Arm 3D Printed Skeleton is an open-source robotic arm kit designed for education, research, and AI-driven applications. Featuring a 6-degree-of-freedom design, it utilizes high-torque STS3215 bus servos and a 12-bit magnetic encoder for precise angle sensing. The arm communicates via UART and is compatible with the LeRobot framework, enabling tasks like data collection, simulation, training, and deployment. Optimized for integration with NVIDIA Jetson devices, including Seeed Studios reComputer J4012 mini PC with Jetson Orin NX, it supports real-time processing and model training.

Feature

• Open-source and low-cost: It is an open-source, low-cost robotic arm solution fromTheRobotStudio.
• Integration with LeRobot: Designed for integration withLeRobot platformwhich offers PyTorch models, datasets and tools for reinforcement learning and imitation learning for real-world robotics applications (including data collection, simulation, training and deployment).
• Abundant learning resources: Provides comprehensive open-source learning resources like assembly and calibration guides, and tutorials for testing, data collection, training and deployment to assist users in quickly getting started and developing robotic applications.
• Compatible with Nvidia: Deploy this arm kit with reComputer J4012 Orin NX 16 GB.

Specification

Application

Imitation learning and Reinforcement learning

The LeRobot framework is compatible with the SO-ARM100 robotic arm. It provides complete data collection, training, and deployment for teaching the robotic arm, and also has a comprehensive simulation platform. On the Nvidia Jetson edge device, it’s easy and quick to train a customized robotic arm to complete grasping and placing tasks. For detailed tutorials, please refer to:LeRobot – NVIDIA Jetson AI Lab
