Write your own controller for a Unitree robot with SDK2

Quad, Hard

unitree_sdk2 is Unitree's C++ SDK for its current robots, with examples for high-level motion and low-level joint control.

View build on GitHub ↗Share on X

Build the SDK on Ubuntu (x86_64 or aarch64), run the examples over Ethernet to your robot, and script sport-mode moves or read the IMU and joints. A Python wrapper (unitree_sdk2_python) also exists.

Hardware & cost: A Unitree Go2, B2, G1 or H1. Ubuntu 20.04+ with CMake and GCC.

Difficulty: Hard. Always test low-level control with the robot hung or lying down.

Agent install prompt (paste into Claude Code, Cursor or Codex): "Clone https://github.com/unitreerobotics/unitree_sdk2, install CMake/GCC per the README, build it, and walk me through running a high-level sport-mode example over my robot's network interface."

How your agent drives it

Copied from the unitreerobotics/unitree_sdk2 README

C++ SDK

Shell
```
$ mkdir build
cd build
cmake ..
make
```

Any coding agent that can run a shell can run these. Read the README before you run anything on a robot that moves.

Ideas to try with it

Our ideas, not the builder's claims.

Write a tiny C++ program that makes the Go2 sit when you clap
Build a follow-me mode on top of the high-level motion examples
Log joint torques during a walk and plot them
