View guide →Unitree's official C++ SDK v2 for programming its robots, with CMake examples and installable library.
unitree_sdk2 is an open-source dev tools project by unitreerobotics (unitreerobotics/unitree_sdk2 on GitHub). It has 1,392 GitHub stars and 393 forks, is released under the BSD-3-Clause license, and was last updated on GitHub on 21 September 2026.
Confirm you have a supported setup: Ubuntu 20.04, a compatible CPU architecture, and access to a Unitree robot or its network.
Clone the repository and install the documented build dependencies with apt.
Build the bundled examples with CMake and Make to verify the toolchain works.
Install the SDK to the system or a custom prefix, then import it into your own CMake project following the included sample.
The supported C++ interface for building applications on Unitree robots, maintained by the manufacturer.
Example programs in the repository demonstrate SDK usage and can be built together with CMake.
Install to the system directory or a custom location such as /opt/unitree_robotics, with find_package integration for your own projects.
A single apt command installs the required CMake, compiler, and library dependencies on Ubuntu 20.04.
An example/cmake_sample project shows exactly how to import the installed SDK into an external application.
The README directs developers to Unitree's official documentation centre for deeper API reference.
Get the source and examples locally.
git clone https://github.com/unitreerobotics/unitree_sdk2.git
cd unitree_sdk2Install the documented packages, then configure and build.
apt-get update && apt-get install -y cmake g++ build-essential libyaml-cpp-dev libeigen3-dev libboost-all-dev libfmt-dev
mkdir build && cd build && cmake .. && makeInstall to the default prefix used by Unitree's samples.
cmake .. -DCMAKE_INSTALL_PREFIX=/opt/unitree_robotics
sudo make installIt is maintained by Unitree Robotics, the robot manufacturer.
Yes, it is BSD-3-Clause licensed and free to use with attribution; the robots themselves are commercial hardware.
No API key is needed; the SDK runs locally and talks to your robot over your own network.
Third-party Python wrappers trade performance and official support for convenience; this is the manufacturer's own C++ SDK that those wrappers typically build on.
Clone the repo, install the listed apt dependencies, build the examples with cmake and make, then install the SDK and copy the cmake_sample pattern.
