ROS Setup

How to install ROS.

Robot Operating System (ROS) is robotics middleware. Although it is not an operating system, it provides services designed for a heterogeneous computer cluster such as hardware abstraction, low-level device control, implementation of commonly used functionality, message-passing between processes, and package management.

curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -

# installation
sudo apt update
sudo apt install ros-noetic-desktop-full

#initialize rosdep
sudo apt install python3-rosdep #if you have not yet installed rosdep,run this line otherwise skip
sudo rosdep init
rosdep update

# setup environment
echo "source /opt/ros/noetic/setup.bash" >> ~/.bashrc
source ~/.bashrc

# fulfill dependencies
sudo apt install python3-rosdep python3-rosinstall python3-rosinstall-generator python3-wstool build-essential  ```
