How It Works

Three steps from unboxing to an autonomous AI robot

1

Teleoperate

Move the leader arm by hand — the follower mirrors your movements in real-time. No code needed.

python lerobot/scripts/control_robot.py \
  --robot.type=so100 \
  --control.type=teleoperate
2

Record & Train

Record 50 demonstrations of a task, then train an AI policy with one command.

python lerobot/scripts/train.py \
  --dataset.repo_id=you/data \
  --policy.type=act
3

Deploy

Watch your robot perform the task autonomously using the trained neural network.

python lerobot/scripts/control_robot.py \
  --robot.type=so100 \
  --control.type=replay

See It in Action

SO100 leader arm

Leader arm — move this by hand to control the follower

SO100 follower arm

Follower arm — mirrors movements and executes AI policies

SO100 quick assembly

Pre-assembled — ready in ~35 minutes from unboxing

SO100 URDF 3D model

Full URDF included for simulation in Gazebo/MuJoCo

Why Makers Choose SO100

No 3D Printer Needed

All structural parts come pre-printed and assembled. Skip the 30+ hours of printing and assembly.

100% Open Source

Hardware CAD files, firmware, software — everything is open. Modify, extend, and hack to your heart's content.

LeRobot Native

The #1 recommended hardware for HuggingFace's LeRobot framework. First-class support, no adapters needed.

Real AI, Not Toy AI

Train actual transformer-based policies using imitation learning. This is the same tech used in research labs.

Two Arms = More Fun

Leader-follower teleoperation out of the box. Most kits only ship one arm — SO100 gives you the complete system.
