Hello, I am begginer in ROS and I want to implement a project. My goal is to simulate a robot which is capable of following a path from an initial position to the goal position, back to initial and so on...Also 4 different types of algorithms for obstacle avoidance should be import to the project. I have made the mapping procedure and the navigation to a goal position with moveback package and DWAplanner, which i think uses Dijkstra's algorithms. I dont know the nafv and DWA what kind of algorithm for obstacles avoidance use. Searching for those problems i found carrot planner, baseglobal and TEB but I dont know if those are the solutions.I also use kinetic and turtlebot3. Every information is very important to me. Thank you
