### 1.1 Mujoco Simulator
Please use **C++ Simulation** in this [Mujoco Simulation](https://github.com/legubiao/unitree_mujoco) for more robot
models and contact sensor.
* **Python Simulation** is also supported, but you still need to
install [unitree_sdk2](https://github.com/unitreerobotics/unitree_sdk2)
### 1.1 Mujoco Simulator or Real Unitree Robot
> **Warning:** CycloneDDS ROS2 RMW may conflict with unitree_sdk2. If you cannot launch unitree mujoco simulation
> without `sudo`, then you cannot used `unitree_mujoco_hardware`. This conflict could be solved by one of below two
> methods:
> 1. Uninstall CycloneDDS ROS2 RMW, or
> 1. Uninstall CycloneDDS ROS2 RMW, used another ROS2 RMW, such as FastDDS **[Recommended]**.
> 2. Follow the guide in [unitree_ros2](https://github.com/unitreerobotics/unitree_ros2) to configure the ROS2 RMW by
compiling cyclone dds.

> * Don't forget to disable the **Official Locomotion Controller** in the robot before the test
