Welocme to introdution to ROS

I hope all have installed Vritual box and and installed the ROSworkshop image which contain ROS open termial with shortcut

Ctrl+Alt+t

Let’s make our first ROS workspace

mkdir -p ROS_workspace/src

the above will create a ROS work workspace ROS_workspace repalce it with a name you are comfortable with names like below

• ROS_ws
• my_ws
• mypacks
• mypacks_ws

For this workshop the Drirectory name is ROSworksop

Now move to directory of ROSworksop and then to src folder using terminal commands this can be done in two methods

• first method

  cd ROSworksop
  cd src
  

• Second method

  cd ROSworksop/src

Creating a package

make sure you are in src

catkin_create_pkg package_name <depend1> <depend2> <...> etc

example

catkin_create_pkg ros_basics roscpp rospy std_msgs

go back to directory of ROSworksop from src folder

cd ..

Now final commands

• first

  catkin_make
  

• after that

  #to move from directory to home
  cd ..
  

• then to enable this package in ROS native packs you can do in 2 methods

  source ~/ROSworksop/devel/setup.sh
  # each time you need to do above command
  # when open termial if you did'nt added to .bashrc file
  # to avoid it
  echo "source ~/ROSworksop/devel/setup.sh" >> .bashrc
