2019-10-15 02:10:44 -0500 | marked best answer | sequence of goals on rviz for robot navigation Hi every one, I want my TurtleBot robot to navigate on environment map autonomous. I found that it is using amcl, which allow to give a goal to the robot in rviz then robot will move to it, but this is not so great. I found that there is exploration I still try to run it.
:
now I want to know 1- If I can give the robot a sequence of goals instead of one goal on rviz to work as if it explore all the environment not just move to one place on it ?! 2- If I can link each goal with specific action for example to do object recognition at specific point on the map ?! Thanks, |

2014-04-20 06:53:40 -0500 | marked best answer | `Message No map received` in Rviz Hi, I try to build a map in Rviz using turtlebot simulation in gazebo. First I create a package and write a launch file which open GAZEBO world and turtlebot in that environment ... That is the Launch file <launch>
<node name="gazebo" pkg="gazebo" type="gazebo" args="-u $(find gazebo_worlds)/worlds/simple_office.world"/>
<param name="/use_sim_time" value="true"/>
<node name="gazebo_gui" pkg="gazebo" type="gui"/>
<include file="$(find turtlebot_gazebo)/launch/robot.launch"/>
<include file="$(find turtlebot_teleop)/keyboard_teleop.launch"/>
</launch>
Then I run rosrun gmapping slam_gmapping scan:=base_scan _odom_frame:=odom_combined Then open Rviz with rosrun rviz rviz -d 'rospack find turtlebot_navigation' /nav_rviz.vcg , this command does not open plugins required for gmapping as it can not locate nav_rviz.vcg, so finally I open rviz from launch file <launch>
<node pkg="rviz" type="rviz" name="$(anon rviz)" args="-d $(find turtlebot_navigation)/nav_rviz.vcg"> </node>
</launch>
It work well at lest it run all requirements for gmapping .... The problem now that when I move robot in gazebo, robot move in rviz too but does not make a map, and I find that massage in rviz : Message No map received Edit
I write this command amal@amal-HP-G62-Notebook-PC:~$ rosrun gmapping slam_gmapping scan:=base_scan _odom_frame:=odom_combined
and nothing else in is written in terminal
see warning All nodes that run and topics Edit2 That is the map
but I think it will not accurate if there is more details in the environment and It seems to be footprints !! Edit3 Hi, I have a problem now, when I open RVIZ it seem there is a problem in laser scan, map, robot model, and tf here is do not know which file I have to check gyro in !!
That is the error any suggestion ,

Now I set up RoboEarth from this rosinstall ~/fuerte_workspace /opt/ros/fuerte 'http://www.ros.org/wiki/roboearth?action=AttachFile&do=get&target=roboearth.rosinstall'
so it is in fuerte_workspace and also on home since previous set up. I have this when run rosmake roboearth , so why does not go in directory of fuerte_workspace ?! amal@amal-HP-G62-Notebook-PC:~$ cd ~/fuerte_workspace
amal@amal-HP-G62-Notebook-PC:~/fuerte_workspace$ rosmake roboearth

2014-04-20 06:52:20 -0500 | marked best answer | I have a Problem in parsing OWL to Prolog Triples Hi all, (((1)))I do not have more experience in KnowRob, so I now try to run command and see its effects and so on
I was trying to parse Owl file into Prolog so I use this command owl_parse('home/amal/pizza.owl', false, false, true).
I get this error bash: syntax error near unexpected token `'home/amal/pizza.owl','
1- What is the Problem 2- I do not Understand Why false false true in the command ?! (((2))) It always give me false, I flow this tutorial (Reasoning about objects at knowrob wiki) and also get false, so what is the problem Terminal: amal@amal-HP-G62-Notebook-PC:~$ roscd knowrob_tutorial
amal@amal-HP-G62-Notebook-PC:~/ros/pkgs/tum-ros-pkg/knowledge/knowrob_tutorial$ rosrun rosprolog rosprolog knowrob_tutorial
