-sudo add-apt-repository "deb http://realsense-hw-public.s3.amazonaws.com/Debian/apt-repo xenial main"

-sudo apt-get install librealsense2-dkms # enter a key for installing driver when asked (in my case the pw was realsense2019bt)
-sudo apt-get install librealsense2-utils
-
-Check if drivers were installed sucessfully:
-modinfo uvcvideo | grep "version:" # -> this should report the realsense camera driver
-
-
-# Installing the ROS package (assuming ros base is installed):
-Install dependencies:
-sudo apt-get install ros-kinetic-cv-bridge -y
-sudo apt-get install ros-kinetic-image-transport
-sudo apt-get install ros-kinetic-tf -y
-sudo apt-get install ros-kinetic-diagnostic-updater -y

-# clone github repo:
-git clone https://github.com/IntelRealSense/realsense-ros.git
-cd realsense-ros/

-catkin_make install
-echo "source ~/realsense_catkin_ws/devel/setup.bash" >> ~/.bashrc
-source ~/.bashrc
-
-Test with:
-roslaunch realsense2_camera rs_camera.launch
-
-Possible issue:
-The camera requires a USB 3 port to provide full resolution streams

-Creating ros package with catkin and adding custom messages:
-############################################################
-1. Create a workspace:
-----------------------
-$ mkdir catkin_ws
-$ cd catkin_ws
-$ mkdir src
-$ catkin_make
-$ source devel/setup.bash
-
-2. Create the package:
-----------------------
-$ cd catkin_ws/src
-$ catkin_create_pkg <package_name> std_msgs rospy roscpp
-$ cd ..
-$ catkin_make # this build the package
-
-3. Create the custom messages:
-------------------------------
-$ cd catkin_ws/src/<package_name>
-$ mkdir msg
-$ cd msg
-$ echo "int64 num" > Num.msg
-Then edit the package.xml file and add the following:
-  <build_depend>message_generation</build_depend>
-  <exec_depend>message_runtime</exec_depend>
-
-Also edit CMakeLists.txt and to the find_package() function add:
- message_generation
-and to the catkin_package() add:
- CATKIN_DEPENDS message_runtime
-
-Then, find add_message_files() (uncomment if necessary) and change it to the following:
-add_message_files(
-  FILES
-  Num.msg
-)
-
-Finally, uncomment the generate_messages() function such that it reads:
- generate_messages(
-   DEPENDENCIES
-   std_msgs
- )
-
-To build the new messages do the following:
-$ cd catkin_ws
-$ catkin_make # builds the new messages
-$ catkin_make install
-
-As the last step, source the setup.bash:
-$ . install/setup.bash
-
-Now the new messages should be available and you can find them with
-$ rosmsg list
-
-Don't forget to source the setup.bash everytime you want to use the messages!
