Hi, i am new to ROS and want to learn about it, i am facing difficulties in installing ROS, i want to create two nodes on ROS, and want them to communicate and analyze the robot's local and global reference frames. To be precise i want to examine the position of the robot in x, y and theta coordinates, then send this result to another node which will convert it to global reference frame and then send it to another node. The thing is i am unable to install ROS, can someone experienced help me out here, i will be really obliged.

Check in /opt and see if there is a directory called "ros". Alternatively, try "source /opt/ros/<distro>/setup.bash" where DISTRO is the distribution you think you've installed (indigo, jade, etc.). If neither works, you don't have ROS

Did you type in "<distro>" specifically? You need to replace "<distro>" with something like "hydro" or "indigo" or "jade"
