2013-11-26 03:19:24 -0500 asked a question Navigation with groovy and catkin, where to start ?

Hi,

I have a task to do : I want to move my robot from one position to another position.

I have a real robot, but I want to try it first with the simulated one. I launch is with this command "rosrun stage stageros /robot/underground.world". I also have the map, and I launch the map server with this command "rosrun map_server map_server /robot/underground.yaml". I want to move it from its current position to a known position in the map.

I want to use the navigation stack. I've been reading tutorials about it which led me to others tutorials, which led me to example packages using this navigation stack. But I haven't find any package working with catkin. They all use rosmake. In fact I don't event want to use a package someone made, I just want to understand the navigation stack and use it my way. But I got lost in these endless self referring tutorials and ... I'd like to see some light :)

That's why I came here. Does anyone know how to do this task : setting up the navigation stack for the simulated robot, send the robot a nav goal by rviz, and see the robot actually go to that position ? (I know how to use rviz, and later i'll just publish in the topic instead of using rviz to send the nav goal, i'll be programming in c++)

Thank you for your help !

Pauline

thank you for your help, it worked by doing 'sudo apt-get install ros-groovy-slam-gmapping' instead of following the tutorial. (see the answer below for more details) :)

It's catkin, see the line : find_package(catkin REQUIRED nav_msgs openslam_gmapping roscpp rostest tf)

How do I check that ?

Thanks for your quick answer :)

I have ros groovy. To download the package I followed the instructions of the ros wiki tutorial at this address :

http:// wiki.ros.org/ catkin/
Tutorials/ using_rosbuild_with_catkin

Here are the command I executed :

$ cd ~/rosbuild_ws
$ wstool set gmapping --git https:// github.com/ ros-perception/ slam_gmapping.git
$ rosws update gmapping
$ source setup.bash

Here you can see that the package sources are on github.

Hi,

I'm programming in c++ and I use catkin. I wanted to work with amcl node. But since it's not catkinised yet, I had to use the gmapping node. I followed the tutorial from here:

http:// wiki.ros.org/ catkin/ Tutorials/ using_rosbuild_with_catkin

to get this node. I did each step. Now I want to run the node with the command

$ rosrun gmapping slam_gmapping scan:=base_scan

but it doesn't work, see the error message :

[rosrun] Couldn't find executable named slam_gmapping below /home/pauline/ros_ws/gmapping/gmapping

(I found the command to run it in here http:// wiki.ros.org/ gmapping)

I don't understand because I did

$ rosmake gmapping

and it was successfull. Am I missing something here ??

Thanks for your help
