Hector Exploration Launch file
Hi,
I am trying to launch hector exploration with my turtlebot with just an RPLidar A2 sensor. I am unsure what is required in the launch file to get hector exploration to work and also not sure what I should key in for the hector_exploration_planner node in the launch file (I keep getting this error:- ERROR: cannot launch node of type [hector_exploration_planner/hector_exploration_base_global_planner_plugin ]: can't locate node [hector_exploration_base_global_planner_plugin ] in package [hector_exploration_planner] ).
Any idea how to go about doing it? Any sample launch files that are available for viewing?
I am using the Hector Navigation stack from this link:
https://github.com/tu-darmstadt-ros-pkg/hector_navigation
Thanks in advance!

It is assured that these parameters are loaded before the start of the nodes presents in the same launch file?

Use param for remapping in launch file
Hello,
I have several nodes with common parameters so I tought it would be nice for debugging to have all of them just in one file and not in all of them. This is working fine but the problem is that remapping it is not able to retrieve this parameters. Is there any way for doing this? Either using the ROS API either scripting?

Best tutorial on Hector Slam implementation, trying to resolve TF issues
I have been working on this for about a week, I have run up against the normal issues and I am looking for a tutorial to help me through the next phase. Here is what I have done thus far:
I have ros(kinetic) master installed communicating with a remote ros(indigo) machine that publishes data via rosserial from an rplidarA2 mounted on a differential drive mobile arduino controlled bot( no wheel encoders).
Hector slam package is installed and functions when playing back the tutorials bagfile. If I attempt to switch to live data I can see the data, so I know it is present,but, I cant seem to get the live data and hector slam to play well together and publish the odom data.
Current list of ongoing TASKS:
**Implement Hector Slam with live data from RPLidar A2 Unit.**
1. **Implement Hector Slam with live data from RPLidar A2 Unit.**
2. Finish Differential Drive arduino code.
3. Install ros navigation stack, and tie the differential drive, lidar, and odom data together.
4. Begin working with MoveIt for Trajectory planning.
I need the Hector-Slam to work before, I can progress much further, I have attempted to work through all the tutorials I have found and have scoured this forum for applicable suggestions, specifically the correct way to launch RViz with live data from lidar.
I am not asking for a handout, just a hand up, if you respond with--- go read the ros hector slam wiki, it is not helpful been there done that have like 15 t-shirts.....
I do thank you for reading this far and all who have helped me make it thus far. This forum is full of experience, knowledge
and great people.
Looking forward to your suggestions,
Best regards,

Using prebuilt Map with AMCL launch file- how to execute with RVIZ
I currently have made my map using Hector Slam and saved the map as .yaml file and .pgm .
I have downloaded the Navigation stack as well using git source: https://github.com/ros-planning/navigation.git . Also ran catkin_make afterwards.
Now, I am trying to implement AMCL by placing my robot( irobot create 2) onto the map and do autonomous mapping.
After researching online, I have come to know about creating my own launch file. However, the github website came with a amcl_diff launch file and I am not sure how to properly execute it with my robot and LIDAR instrument.
Please find below code for amcl_diff.

Ros nodes not starting from a launch file
'm trying to create a launch file for starting all the nodes. But for some reason, running the launch file doesn't run the node. The topic in which the node publishes is listed when I run rostopic list, but when I try to echo, nothing is displayed.
On the other hand if I just do a rosrun, it all works perfectly fine.
This is my launch file:

Issues launching ROS on startup
ROS: groovy
OS: ubuntu 12.04
What we are trying to do is have roscore start upon boot (have this working now) and then execute a launch file.
I am not a linux person, so I feel I am really not approaching this the right way. Currently, this is what I have attempted:
1) roscore is launched via a script in /etc/init.d. This is fine.
2) I want to launch my launch file on boot. Manually, I do it like this: roslaunch rover.launch. It works great.
3) I would like this to start on boot, so I tried the following:
inside new script (boot.sh) - note i disabled password prompt for sudo:
sudo su - roboops
/home/roboops/groovycat/scripts/bootRoverLaunch.sh
bootRoverLaunch.sh:
cd /home/roboops/groovycat/
source devel/setup.sh
sleep 5
roslaunch rover.launch > /home/roboops/groovycat/scripts/startup.log
4) I went to "startup applications" and added "bash /home/roboops/groovycat/scripts/boot.sh"
5) Tried rebooting. Roscore starts, and the launch files executes. However, the nodes malfunction and don't work correctly (They work fine when started using the launch file directly in a terminal window. Oddly, it also works fine if I log out and back in once)
More specifically, here is the problem when using the above script to launch:
I am trying to run two nodes:
-joystick node (publishes joy topic)
-motor control node (listens to joy topic and outputs commands to motor controllers via serial)
Joystick node starts successfully and If I do rostopic echo joy, I can see the values.
Motor control node is listed as running but if I run roswtf it says:
Found 3 error(s).
ERROR Could not contact the following nodes:
* /Drivetrain
ERROR The following nodes should be connected but aren't:
* /Drivetrain->/rosout (/rosout)
ERROR Errors connecting to the following services:
* service [/Drivetrain/get_loggers] appears to be malfunctioning: Unable to communicate with service [/Drivetrain/get_loggers], address [rosrpc://Rover:58631]
* service [/Drivetrain/set_logger_level] appears to be malfunctioning: Unable to communicate with service [/Drivetrain/set_logger_level], address [rosrpc://Rover:58631]
The idea is, I need everything to automatically start on power-up. There will be no input devices/monitor connected to it when it is in use.

Launching hector_pose_estimation error
Hello ROS peeps,
I am a newbie to ROS, I am trying to run hector_localization package i followed the hector tutorial from [here](https://github.com/tu-darmstadt-ros-pkg/hector_localization)
**How to run the code**
> $ cd catkin_ws git clone>$ git@github.com:tu-darmstadt-ros-pkg/hector_localization.git>$ catkin_make --source hector_localization roslaunch>$ hector_pose_estimation hector_pose_estimation.launch
after I launch the hector_pose_estimation.launch i got the following error.
From the previous question, I just clone the geographic_info in my catkin_ws so i can build/make the hector_localization successfully.
I am not sure why I got the error like this
Any configuration I need to set up?
Thanks in advance!
