I switched from ubuntu 14.04 to ubuntu 16.04 and try to completely remove ros indigo and install ros kinetic and gazebo9 I followed a guide to install . This is a lists of my command on terminal:

cd ~/catkin_ws/src

1) git clone https://github.com/ROBOTIS-GIT/turtle...

2) git clone https://github.com/ROBOTIS-GIT/turtle...

3) git clone https://github.com/ROBOTIS-GIT/turtle...

4) cd ~/catkin_ws && catkin_make && source ~/catkin_ws/devel/setup.bash

cd ..

catkin_make

This is the last part of output

Suggestions? I'm a newbie on ROS

Hi, i tried to develop in C++ with success (basically i'm still a beginner with ROS development) a way for autonomous exploration of n turtlebot3 in an unknown environment (like turtlebot3 house for example). The algorithm is too much "simple",basically i check the laserscan distance from an obstacle and if obstacle distance is less than 0.5 meter robots turn left by 90 degrees.

What i'm looking for now is a more sophisticated algorithm to implement in C++ and an algorithm that "turn aroung" fixed and mobile obstacles (like walking human for example)

I found the relaxed A* algorithm on github but it's useless for me cause it's based on well known map and find the optimal path from a start to a goal point. Suggestions?

@PeterBlackerThe3rd could you link me doc about how to setup map?

when you talking about threshold do you intend ,for example: <param name="resampleThreshold" value="0.5"/> insi

Could you explain what is it for vector <int> RAstarPlannerROS::findFreeNeighborCell (int CellID) Why it has 2

maybe you need to source your setup.bash file I did it the same package without problem

Ok I solved. I made several errors : 1)I didn't generate map with gmapping node 2)Error of localization , in the amcl.la

map_server can't load map I have this launch file in order to use nagigation stack. I follower a tutorial on robotignite

edit: updated original post

Just an updated because @davidportugal asked me to show the files

this is my amcl.launch.xml that i call inside turtlebot3_navigation_path_planning_1.launch <launch> <arg na

i tried,no output ,map doesn't crash but if i run : rospitc /list i only have: 1)rosout 2)rosout_agg
