Hi,
I am specifically interested in predicting the next move of autonomous navigator of ROS.
What should be the packages, I need to look at. I have gone through this page ?
Many thanks for any kind of help.
for planning and navigation, ROS uses a node called move_base. Roughly, it divides the planning problem in two parts, the first creates a complete path from the start to the goal and is called global planner and another part creates local trajectories so the robot can follow the global path, and is called local planner. In the way this node is implemented, it allow you to use different local and global planners. By default, the global planner is called navfn, which implements Dijkstra's algorithm. For more info:
for more details, you can check here Writing A Global Path Planner As Plugin in ROS. If my response answered your question, pleas mark it as correct.

what do you mean by "predicting the next move of autonomous navigator" ?
By "Predicting the next move"; I want to say how the trajectories have been chosen+constructed+updated? and how these trajectories can be modified?
