Hello Everyone,
I am completely new to ROS and programming in C++, I am looking for a program to move the turtlebot forward and found a tutorial named sending simple goals to navigation stack. However, I tried the tutorial (http://wiki.ros.org/navigation/Tutorials/SendingSimpleGoals) to move the robot forward by 1 meter. I have followed the tutorial in the exact way but unable to execute the program and it shows an error message:
asun@asun-Latitude-E6400:~$ rosrun simple_navigation_goals simple_navigation_goals
[rosrun] Couldn't find executable named simple_navigation_goals below /home/asun/catkin_ws/src/simple_navigation_goals
[rosrun] Found the following, but they're either not files,
[rosrun] or not executable:
[rosrun] /home/asun/catkin_ws/src/simple_navigation_goals
[rosrun] /home/asun/catkin_ws/src/simple_navigation_goals/include/simple_navigation_goals
I can see the executable file under this folder:
home/asun/catkin_ws/src/simple_navigation_goals/include/simple_navigation_goals
Please help me with the solution. I am using ROS-Hydro and Ubuntu 12.04 LTS precise.
Also, I am completely new to this. Please help me with any tutorial in C++ or python to move the robot forward or backward in the simulator as well as the turtlebot itself using code but not teleop.
Any help will be much appreciated.
I have built the code using catkin_make and it produced the following result:

Then i have executed the program using command
rosrun simple_navigation_goals simple_navigation_goals
but this time it shows a new error which doesnt make sense, as i have created a package myself as per the tutorial.
asun@asun-Latitude-E6400:~/catkin_ws$ rosrun simple_navigation_goals simple_navigation_goals
[rospack] Error: stack/package simple_navigation_goals not found
