As it is essential to get octomap for navigation and path planning but I am not able to do that I have followed the answer also but it isnt helping. https://answers.ros.org/question/9712...

There is also error while opening pcd files from the rgbdslam_v2 GUI. The error of opening of pcd file is this:

[ERROR] [1506803049.883978384]: Cloud has "flat" dimensions: 1 x 14585991

I am using roslaunch rgbdslam rgbdslam.launch

and then play my rosbag file and the GUI is building 3D map but not octomap. Once the process is over I try to save the octomap but the only output I am getting is this(this is map.ot file generated from save octomap):

Octomap OcTree file

(feel free to add / change comments, but leave the first line as it is!)

# id ColorOcTree size 0 res 0.05 data

I am noob at slam but I know bit of ros I have gone through every answer on the ros answers but it isnt helping me can anyone help me with this I would be pleased and can you tell me how to view octomap i have installed octavis.

can you tell me how are you controlling the motors I have written the following code in arduino but its not efficient ca

Where is the function set_speed and how are you writing it in arduino can you give me example of that?

I know the algorithms of the SLAM but I want to implement my own code without using gmapping I know how SLAM is implemented but don't know how to integrate it with ROS. Is their any guide I also know how to publish nodes in Ros but what I have to do to create a map from laser data without using gmapping or any ROS commands. Can anyone help?

Thanks for the above answer the return true thing worked I got binary octomap

Hey Felix!!! Can you expand more on point 1 and yaa I am also getting empty file through GUI. What to do

I am running rosrun depthimage_to_laserscan depthimage_to_laserscan and the scan topic is published and when I rosbag record -o /scan /tf the scan topic is not been recorded and the map is not created. I am new to ros and also read thewiki page bit didn't understand how to do that any suggestion. I want to make a 2D map to implement localization.

For basic go with ROS TUTORIALS and Programming Robots with ROS O'Rielly and then go for Mastering ROS by Lentin Joseph

Thanks this will surely help can u give your email id if I get stuck some where I can mail you. Thanks in advance

Hey I am also trying to implement autonomous navigation for my project I have learned the theory but I am not able to i

Problem in implementing SLAM in ROS I know the algorithms of the SLAM but I want to implement my own code without using

bash: source/opt/ros/indigo/setup.bash: No such file or directory I am getting this problem. And the path is also correct. And I installed all the things thrice but still the same problem. while I am able to open gedit .bashrc. can somebody help.....

yeah i have done this to and followed each and every step thats why i got the map from gazebo but when i am trying to do this p3dx on actual ground its not working. Have i made any mistake in tf orsomething

I recorded the data in rosbag file of /tf and /scan topics and when i run the gmapping and playback the recorded data from rosbag file nothing changes. And the error is 100% messages dropped.Do i have to record different topic and do i need to do something in the tf topic or not. The scan noe is created by depthimage_to_laserscan and the /scan node is working but the map is not building whats the error. I have implemented same method in gazebo and its working but with p3dx its not working. I have followed from the book programming robots with ros.
