What is the primary reason why the agent robot gets lost its pose when making map?
Hello, I'm using ROS kinetic with Ubuntu 16.04.
I have to get pose data of the agent robot in order to get a navigation path plan.
amcl_node can provide the needed data, but because 'amcl_node' includes so many particles
to calculate the agent's pose, it does not come in time for the certain algorithm process I made.
I had also tried hector_slam and saw a few teams did localization or other things in an unknown environment using hector_slam.
In my case, however, when the agent robot gets faster or detects an unknow place (in other words, when the robot just goes somewhere.), the pose data also goes wrong; suddenly being changed its cartesian coordinates.)
How can I get the robot pose with more and more robustness? I would have thought that unless the robot gets a rather fast velocity, it would not lose its robustness; And I was wrong.
If someone who has ever used hector_slam or is familiar with localization packages is here, would you please give me helpful advice?
(And just so you know, I've also launched amcl_node only just in order to designate a goal point with a simple mouse-clicking, when I run the hector_slam. Does this have something to do with the problem?)
Thanks in advance. :)
