how to omit the step of setup.bash every time?
I am new in ROS. I have a question.
When I use ROS, I have to do like this every time I start new window of Terminal.
$ source ~/catkin_ws/devel/setup.bash
and this step enable me to use "roscd".
Do I have to do this step every time? Or does anyone know how to skip this step? If there is a website about this, please let me know.
