Ros Noetic

NOTE: Use this code below if you want to automatize all the process of installation

Run in your terminal:

sh -c "$(curl -fsSL https://raw.githubusercontent.com/Insper/404/master/scripts_robotica/install_ros_noetic.sh)"

To do step by step:

To install opencv4+, use this commands below:

sudo apt update 
sudo apt install libopencv-dev python3-opencv
sudo apt install python3-pip
pip3 install --user opencv-contrib-python

Test if worked:

python3 -c "import cv2; print(cv2.__version__)"

Install Ros Noetic

Setup your sources.list

It's always a good idea to backup a configuration file like sources.list before you edit it. To do so, issue the following command:

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

By editing these files from the command line, we can add, remove, or temporarily disable software repositories.

Adding the Universe and Multiverse Repositories

You may use the add-apt-repository command. If your release is 'saucy':

sudo add-apt-repository "deb http://us.archive.ubuntu.com/ubuntu/ saucy universe multiverse"
sudo add-apt-repository "deb http://us.archive.ubuntu.com/ubuntu/ saucy-updates universe multiverse"you may use the add-apt-repository command. If your release is 'saucy':

Setup your sources.list

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'

Set up your keys

sudo apt install curl # if you haven't already installed curl
curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -

Don't forget to retrieve the updated package lists:

sudo apt update
