SO-ARM101 Advanced Dual Camera Kit - Unassembled (EU)
Description
SO-ARM101 Open-Source 6-Axis Robotic Arm, native support for Hugging Face LeRobot, High-Torque Bus Servo, Photosensitive resin 3D-printed parts
Simultaneously updated with the official Hugging Face project

To lower the entry barrier for beginners, some of our kits include the parts such as high-definition cameras, USB hubs, and metal desk-mount arms for cameras. After unboxing and assembly, you can run the official examples without any additional hardware

the robotic arm moves more flexibly and freely with 6-DoF spatial motion, easily performing complex tasks such as grasping and handling

High precision and strong grip
The SO-ARM100 series is equipped with bus servos rated at 19.5 kg·cm @ 7.4V torque, while the SO-ARM101 series uses bus servos rated at 30 kg·cm @ 12V torque. Both series feature 12-bit magnetic encoders for joint angle feedback, offering higher precision and improved load capacity
3D-printed structural parts are made from photosensitive resin instead of normal PLA. They offer durability, smooth surfaces, and fine details, combining excellent performance with a premium appearance
Wider Data Collection Coverage
The CAM Kit and Jetson Orin Nano Kit equipped with dual cameras, providing a wider field of view and enhanced perception capabilities to help you effortlessly capture environmental details
The CAM Kit and Jetson Orin Nano Kit equipped with USB hub, allows seamless switching between dual hosts for model training and experiment testing, without repeatedly plugging and unplugging the robotic arm or camera devices, significantly boosting efficiency

Kit Selection Guide

Step 1: Choose the series based on the arm torque
- Higher grip force / higher torque → Choose the SO-ARM101 series (the sub robotic arm uses bus servos rated at 30 kg·cm @ 12V torque)
- Standard teaching / project practice → Choose the SO-ARM100 series (the sub robotic arm bus servos rated at 19.5 kg·cm @ 7.4V torque)
Step 2: If you choose the SO-ARM101 series, and select the teaching feel
- Prioritizing teaching efficiency and a smooth, low-resistance guiding arm → select the packages with the “(SE)” suffix (guiding arm uses virtual servos, better suited for long-duration teaching)
Step 3: No 3D structural parts required? Choose the kit without 3D parts
- You can print 3D structural parts yourself, saving the cost of pre-printed 3D components
Step 4: Need visual and multi-angle data acquisition? Choose the dual-camera kit version [Recommended]
- Vision-ready: Equipped with dual cameras for more comprehensive coverage and more efficient data acquisition
- Flexible with your own main controller: The package includes all necessary accessories except the main board, allowing use with a PC or your existing Jetson Orin Nano board
- High cost-effectiveness: Retains the full feature experience while further lowering the entry cost for robotic arm applications, making development easier and more flexible
Step 5: Need an all-in-one solution? Choose the Jetson Orin Nano kit version
- Paired with the Jetson Orin Nano Super (Waveshare basic kit 8GB version), it enables low-latency, high-throughput AI computing
- The Jetson Orin Nano platform delivers rich interfaces and powerful computing capabilities, enabling robotic arms to perform more effectively in visual recognition, path planning, and real-time feedback. Significantly enhancing the overall scalability and intelligence of the system
- Combined with LeRobot pre-trained and teaching data, you can quickly complete the full workflow from data to strategy to deployment
