nav2d autonomous exploration

edit

@Sebastian Kasperski thanks a lot for answering. I have just edited first post with the current error.!

For the second part you need to make a tf tree. Take a look at this tutorial)

@Icehawk101 I have just fixed that error. Now the error is the next when I call rosservice StartExploration:

[ERROR] Exploration failed, could not get current position.

You should make a second edit to your question with the new information.

@Icehawk101 Done!!

In your launch file are 2 different mapping nodes and 2 different navigation nodes, this will not work.

I have just editted post! @Sebastian Kasperski

You also don't need amcl when using slam. Please check the nav2d tutorials. Does your robot move when you send something to cmd_vel? And check with rostopic echo if something is even send on this topic. With just "The robot doesn't move", nobody can help you.

@Sebastian Kasperski I have just eddited with more information!! thanks!!

@Sebastian Kasperski It gives me this error as well: LaserRangeFinder::Validate() - LocalizedRangeScan contains 672 range readings, expected 673

Your laser scans contain angle_min, angle_max and angle_increment, which should match the supplied number of readings. [num_readings = ((angle_max - angle_min) / angle_increment) + 1] Maybe your laser driver sets these values incorrectly.

It looks like the array holding the range data has a spot with a NULL value for some reason. What driver are you using for the laser?

@Sebastian Kasperski@Icehawk101 Hello my friends. I have just edited the post!!! Thanks again,
