How to install ROS on ubuntu and verify it? [closed]
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, someone experienced can help me out here, i will be really obliged.
Your question is confusing. Are you having troubles installing ROS? If so, what errors are you encountering? Or, are you having difficulty figuring out how to accomplish this two-node demo that you are describing?
Yes i want to create two nodes on ROS, i don't think i have ROS installed on my linux, how am i suppose to know that it is installed and if it is how will i create those two nodes, sorry i am a beginner and would appreciate your help.
Well well. You need to follow the installation instructions. ROS doesn't ship with Ubuntu by default (if you are using ubuntu)
to check if ros is installed or not i've typed "source /opt/ros/<distro>/setup.bash" it says "unversioned" what does it mean?
