QUESTION ABOUT NAVIGATION

[dineshrboson]

IS YOUR VEHICLE CREATES A MAP AND LOCALIZES IN IT AND THEN NAVIGATE IN IT OR IT WILL NAVIGATE IN REAL TIME AND STORES MAP? IS IT SELF DRIVING OR USES ROS NAVIGATION STACK? I WANT TO USE REAL TIME NAVIGATION WITHOUT CREATION OF MAP BUT NOT SELF DRIVING JUST TO FOLLOW A TARGET OBJECT IT NEEDS TO TAKE A PATH AVOIDING OBSTACLES WITH ONBOARD SENSORS AND USING PATH PLANNING ALGORITHMS BUT I DON'T WANT TO CREATE A MAP INITIALLY TO USE AMCL. AND ONE MORE IMPORTANT THING YOU GUYS DIDN'T WRITE HARDWARE INTERFACE NODE THEN HOW THE NAVIGATION STACK IS WORKING HOW THE VELOCITY IS TRANSFERRED AND RVIZ IS UPDATING THE CURRENT POSE OF VEHICLE
