I try to run google cartographer demo and get this follwoing error

[ERROR] [1613722041.399069111, 1588377398.223712458]: PluginlibFactory: The plugin for class 'Submaps' failed to load. Error: Failed to load library /opt/ros/noetic/lib//libcartographer_rviz.so. Make sure that you are calling the PLUGINLIB_EXPORT_CLASS macro in the library code, and that names are consistent between this macro and your XML.

Seem like the PluginlibFactory loads

/opt/ros/noetic/lib//libcartographer_rviz.so

instead of

/opt/ros/noetic/lib/libcartographer_rviz.so

This is should be trivial but I don't know where to apply the solution. This is the submap source code.

I just forget to compile the rviz plugin and its dependency (abseil-cpp) using same C++ standard. After compiling all of

I want to design walking quadruped robot with sprawling configuraion using Dynamixel servo. The navigation use SLAM with XV-LiDAR 11 input. I look on the internet and found towr and Moveit! packages seems can handle the kinematic but I am afraid both will overkill because my robot is should be optimized to walk on even surface in a maze. Maybe package with seamless integration with navigation stack, kinematic, and gait will be much better.

For general leg locomotion gait please check towr package.

Usually I use method of both tf function that only accept source_frame and target_frame. Recently I discover from amcl source code that there is another function overloading that accepts more argumentd like fixed_frame, source_time, target_time. I have read the documentation and still don't understand what is these function and its argument do.

Even more the code from amcl sets target_frame and source_frame value with same frame that is base_frame_id, why?

  // wait a little for the latest tf to become available
  tf_->waitForTransform(base_frame_id_, msg.header.stamp,
                       base_frame_id_, now,
                       odom_frame_id_, ros::Duration(0.5));
  tf_->lookupTransform(base_frame_id_, msg.header.stamp,
                       base_frame_id_, now,
                       odom_frame_id_, tx_odom);
