CNOSolarROS2

Prerequisites

• A Linux-based operating system (e.g., Ubuntu)

• Administrative privileges (sudo access) on your system

Install ros2 humble Ubuntu(debian)

To install ros 2 follow this link, if you don't have too much storage in the machine is possible to install just the ROS-base version.

Add sourcing to your shell startup script [reference]

If you don’t want to have to source the setup file every time you open a new shell, then you can add the command to your shell startup script:

echo "source /opt/ros/humble/setup.bash" >> ~/.bashrc

to have access to colcon variables using tap you can also add this to the shell script

echo "source /usr/share/colcon_argcomplete/hook/colcon-argcomplete.bash" >> ~/.bashrc

Clone the git repository

Create a workspace folder (e.g, Cnosolar_ws) and clone the repository using:

git clone git@github.com:AngelDiaz03/CNOSolarROS2.git

Run the project

Inside the workspace folder, you need to build the project for that use:

colcon build --symlink-install 

Note: The "--symlink-install" flag is to make easier the working process whe you use it, there's no need to build agin every time you change a file.

Then source the insatll folder using:

source install/setup.bash

Is also recommendable to add the source of the install folder to the shell.

echo "source {$PATH}/install/setup.bash" >> ~/.bashrc

where $PATH is the global path to your workspace.

Finally to run the project just use the launch file:

ros2 launch meteorology_data meteorology.launch.xml

Main possible changes

• Meteorology data file:

  To change the data .csv file go to src/meteorology_data/resource and add the fille that you need.

  Then go to src/meteorology_data/meteorology_data/meteorology_node and change the "self.data_file" variable to access the new file.

• Configuration .json file

  To change the config .json file go to src/cnsolar/resource and add the fille that you need.

  Then go to src/meteorology_data/meteorology_data/solar_park_node and change the "self.json_str" path to match the name of the new file.

Future work

• Change meteorology node to get real data in real time.

• Cahnge bridge node to publish the data into a database.
