 # Unitree Go1
+
+Unitree Go1 is one of our legged robots. In this page, we provide the instructions
+that one needs to know to either teleoperate as well as controlling it using ROS.
+
+## Teleoperation with Remote
+
+1. Place battery in robot
+1. **Power on robot**: _Short press_ and then _long press_ the battery power button
+1. **Power remote**: _short press_ and then _long press_ power button
+1. Wait for robot to stand
+1. Follow instructions on remote
+1. **Sit**: 2x L2+A -> L2+B
+1. **Stand**: 2x L2+A -> SELECT
+1. **Power off robot**: Sit robot first and then repeat step 2.
+
+## Control using ROS
+
+A ROS package is available to control the robot using ROS velocity commands as well as receive data from robot. You can install it using the following command:
+
+```sh
+sudo apt install ros-<distro>-unitree-ros
+```
+
+!!! note
+
+ Only humble and iron are supported. For the foxy devel, please consult [package repo](https://github.com/snt-arg/unitree_ros?tab=readme-ov-file#%EF%B8%8F-installation-)
+
+<!-- TODO: Create repo and refer the url for unitree credentials -->
+
+Then, to control the robot, first connect to it's hotspot. The `SSID` should be the one containing **GO1** on it. For the password, refer to [here](). Once connected, run the following command:
+
+```sh
+ros2 launch unitree_ros unitree_driver_launch.py wifi:=true
+```
+
+In case you are connected to the robot via cable, no need to connect to WiFi. Simply run `ros2 launch unitree_ros unitree_driver_launch.py`
+
+!!! tip "More on the ROS package"
+
+ In case you desire to know more about what the package offers, please refer to it's [documentation](https://github.com/snt-arg/unitree_ros).
