ok,thank you very much for everything

okk,thanks. I only want to probe a file that makes that turtlebot turn on groovy but I don't know it (the file is for electric and subcribes to turtlebot_node)

Hello, I'm working with Groovy on Turtlebot (create base).

How could I add the dependency turtlebot_node to my package? I have done the following:

CMakeLists.txt of my package:

cmake_minimum_required(VERSION 2.8.3)   
project(beginner_tutorials)

## Find catkin macros and libraries
## if COMPONENTS list like find_package (catkin REQUIRED COMPONENTS xyz)
## is used, also find other catkin packages
find_package(catkin REQUIRED COMPONENTS roscpp rospy std_msgs turtlebot_node)

Package.xml of my package :

<build_depend>turtlebot_node</build_depend>
<run_depend>turtlebot_node</run_depend>

However when I execute catkin_make in my catkin_ws,I have the following error:

turtlebot@turtlebot:~$ cd ~/catkin_ws/

turtlebot@turtlebot:~/catkin_ws$ catkin_make

Base path: /home/turtlebot/catkin_ws

Could not find a configuration file for package turtlebot_node.

Set turtlebot_node_DIR to the directory containing a CMake configuration file for turtlebot_node. The file will have one of the following names:

turtlebot_nodeConfig.cmake
turtlebot_node-config.cmake

Call Stack (most recent call first): prueba/CMakeLists.txt:7 (find_package)

-- Configuring incomplete, errors occurred! make: * [cmake_check_build_system] Error 1 Invoking "make cmake_check_build_system" failed

Can anyone help me please? I have no idea what is wrong with it.

I would appreciate any feedback.

Thanks in advance.

Hello, I run the following commands in my terminal to create the executable "gira":

mkdir -p ~/catkin_ws/src

cd ~/catkin_ws/src

catkin_init_workspace

cd ~/catkin_ws

catkin_make

source devel/setup.bash

cd ~/catkin_ws/src

catkin_create_pkg beginner_tutorials geometry_msgs image_transport nav_msgs roscpp sensor_msgs std_msgs

I copy gira.cpp in beginner_tutorials/src and I add to CMakeList.txt:

add_executable(gira src/gira.cpp) and target_link_libraries(gira ${catkin_LIBRARIES})

cd ~/catkin_ws

catkin_make

source devel/setup.bash

my ROS_PACKAGE_PATH is: /home/turtlebot/catkin_ws/src/beginner_tutorials:/opt/ros/groovy/share:/opt/ros/groovy/stacks

rosrun beginner_tutorials gira

And does not find the executable, what am I doing wrong? Thanks for help

Solved, I forgot to add target_link_libraries (gira $ {catkin_LIBRARIES}) to CMakeList.txt. Thanks

No, I deleted turtlebot_node dependency because I do not use

when I execute catkin_make in my catkin_ws,I have the following error:

turtlebot@turtlebot:~$ cd ~/catkin_ws/

anyone know to fix it?thanks you for your help

I've only added to CMakeLists.txt add_executable(gira src/gira.cpp). Do I have to change something else in the CMakeLists.txt or package.xml?

hello, when I run catkin_make I get the following errors:

Scanning dependencies of target gira
[100%] Building CXX object prueba/CMakeFiles/gira.dir/src/gira.cpp.o

any idea what could be the mistake? thanks

the executable gira.cpp:

#include "ros/ros.h"   
#include "geometry_msgs/Twist.h"  

int main(int argc, char **argv)
{

ros::init(argc, argv, "gira");   

    ros::NodeHandle n;

    ros::Publisher vel_pub_=n.advertise<geometry_msgs::Twist>("cmd_vel", 1);   

    geometry_msgs::Twist vel;

    ros::Rate loop_rate(10);   

    while (ros::ok())   
    {
        vel.linear.x = 0.1;   //velocidad de avance
        vel.angular.z = 0.3;   //velocidad de giro

        vel_pub_.publish(vel);

        loop_rate.sleep();
    }

    return 0;
}

the CMakeLists.txt (catkin specific configuration and built) :

cmake_minimum_required(VERSION 2.8.3) project(prueba)

find_package(catkin REQUIRED COMPONENTS geometry_msgs image_transport nav_msgs roscpp sensor_msgs std_msgs )

catkin_package( INCLUDE_DIRS include # LIBRARIES prueba # CATKIN_DEPENDS geometry_msgs image_transport nav_msgs roscpp sensor_msgs std_msgs turtlebot_node # DEPENDS system_lib ) ## Specify additional locations of header files ## Your package locations should be listed before other locations include_directories(include ${catkin_INCLUDE_DIRS} )

## Declare a cpp library # add_library(prueba # src/${PROJECT_NAME}/prueba.cpp # )

## Declare a cpp executable # add_executable(prueba_node src/prueba_node.cpp) add_executable(gira src/gira.cpp)

## Add cmake target dependencies of the executable/library ## as an example, message headers may need to be generated before nodes # add_dependencies(prueba_node prueba_generate_messages_cpp)

## Specify libraries to link a library or executable target against # target_link_libraries(prueba_node # ${catkin_LIBRARIES} # )

I have the same problem, this is my .bashrc, any suggestions? export ROS_MASTER_URI=http://192.168.187.116:11311 export ROS_HOSTNAME=192.168.187.116 export TURTLEBOT_BASE=create export TURTLEBOT_STACKS=circles export TURTLEBOT_3D_SENSOR=kinect source /opt/ros/groovy/setup.bash

hello, I have the following error and can not find the way to solve:

/input ports : Stale /kobuki :Stale /Sensors : Stale

any ideas? Thank you very much for your help

I run the dashboard and I get the following errors:

/ kobuki: Stale / input ports: Stale / sensors: Stale

I can not put the full mode turtlebot due to these errors. Any suggestions? (the communication between the workstation and the PC turtlebot working properly)

thank you very much for your help
