I tried to run hector_costmap with hector_slam but I don't see any obstacle information in the Rviz. What changes are required to make the hector_costmap detect obstacles?

Thanks

Hello! I have been trying to integrate pose estimate of robot obtained from apm flight controller using hector_pose_estimation with hector mapping. Whenever I run hector_slam launch file I get the error on terminal for hector_pose estimate (picture attached here ) . The pose can be visualized in Rviz without hector mapping but poses problem with it My TF tree is as shown here ) .

This is my hector_slam.launch file

<launch>

  <arg name="geotiff_map_file_path" default="$(find hector_geotiff)/maps"/>

  <param name="/use_sim_time" value="false"/>

  <node pkg="rviz" type="rviz" name="rviz"
    args="-d $(find hector_slam_launch)/rviz_cfg/mapping_demo.rviz"/>

  <!--<node pkg="tf" type="static_transform_publisher" name="map_basestabilized_broadcaster" args="0 0 0 0 0 0 map base_stabilized 100"/>-->    
  <include file="$(find hector_mapping)/launch/mapping_default.launch"/>

  <include file="$(find hector_geotiff)/launch/geotiff_mapper.launch">
    <arg name="trajectory_source_frame_name" value="scanmatcher_frame"/>
    <arg name="map_file_path" value="$(arg geotiff_map_file_path)"/>
  </include>

    <node pkg="tf" type="static_transform_publisher" name="map_baselink_broadcaster" args="0 0 0 0 0 0 laser map 100"/>
    <node pkg="tf" type="static_transform_publisher" name="baselink_laser_broadcaster" args="0 0 0 0 0 0 base_link laser 100"/>
</launch>

And here is the hector_pose_estimate.launch file

    <?xml version="1.0"?>
<launch>
    <param name="/use_sim_time" value="false"/>

    <node pkg="hector_pose_estimation" type="pose_estimation" name="hector_pose_estimation" /> 

  <!--node pkg="rviz" type="rviz" name="hector_pose_estimation_rviz" args="-d $(find hector_pose_estimation)/rviz_cfg/hector_pose_estimation.rviz" /-->
</launch>

Looking forward to a prompt solution.

Thanks

Regards,

what changes did you make and in which files?

Thanks for the help. Will check it out.

@enddl22 Hello! Which hector_slam packages did you use to achieve this 2.5D Map? I am working on it as well but I could only generate 2D map without pose estimation.

I have an RPLidar A1 and when I plug it in, it just keeps on rotating even when the rplidar node is not running. And, also I don't know its current frequency of rotation and I want to configure it, as it can vary from 5 Hz to 10 Hz, how to do that? What changes do I have to make in the launch file of rplidar in order to start the motor only when I run the rplidar launch file and stop it when the file is closed?

Thanks

I have an RPLidar, an apm flight controller and a sonar sensor(to measure height). I have implemented simple 2D slam using hector_slam package. My objective is to achieve autonomous indoor flight of my quadcopter. What I don't understand is how I can avoid obstacles using the map obtained from hector_slam implementation and navigate freely through the environment.

Any sort of help, a hint, a simple direction will be highly appreciated!

Thanks.

@MarkyMark2012 I have resolved the issue by adding a swap partition following steps given in this link .

@MarkyMark2012 I think I found the problem . I watched the memory using "watch -n 0.5 free -m" as the build process went on. Turns out that the memory is running out.here is the picture when memory almost runs out and rapsberry pi freezes. Any solution?

Sorry for that. I'll be careful next time. As I said before, the system is hanged! I cannot do anything and its just stuck. I am attaching an image here http://imgur.com/a/IM9ey .

I am running ROS kinetic on ubuntu mate 16.04 lts on Raspberry pi 3. I have 3 packages in my src file at the moment, beginner_tutorials, rplidar, hector_slam. The problem appears to be with hector_slam, but I have experienced it with rplidar as well. Whenever I do catkin_make, after a certain percentage(not fixed!) of make process the system (Raspberry Pi 3) gets hanged and there is no way to get around it except restarting. Need help asap please. Thanks

I have a Naza M Flight Controller which can give me the IMU readings (I don't know if I can extract this information by interfacing it with ROS, else I will have to use an external IMU). I also need suggestion for a sonar sensor (my application is for indoor environments) to integrate elevation data in hector_slam . Further, is it even possible to achieve autonomy with an RPLidar, IMU data and Sonar Data?

looking forward! Thanks
