ROS General Query: Dealing with codes
I have been working on ROS for the last 2-3 months. I followed the official ROS tutorials and the book "mastering Ros....". I have worked on the bilt in examples of Rviz,Gazebo,Navigation Stack,Waypoint navigation and Moveit! Now , i need to deal with the core part of ROS and its working.
Ex: let i have implemented Arduino based ultrasonic sensor with ROS and have built its out on the plot, but now i want to get the ultrasonic data which my ROS is dealing with before displaying it on the plot. This probably takes dealing with the python code.
Also, let i have inplemented the 2D NAV Goal option in Rviz, but now i require to process the raw data which my ROS is implementing to make the bot move to the given goal position.
I need several such tasks to do and do not have any much concrete idea of how to start with this.
Kindly help me in this regard. Do i need to be very good with python for this? Or is thete any such specific det of tools of ROS to perform such action??
Regards
