ros cant see the topic /ariac/joint_states

[Former user]

In the .bashrc file i have configured the lines

source /opt/ros/kinetic/setup.bash

export ROS_MASTER_URI=http://192.168.1.73:11311

export ROS_HOSTNAME=192.168.1.73

source /opt/ros/kinetic/setup.bash

source ~/ariac_ws/install/setup.bash

Then I use the next command line to start ROS

$roscore

To show you what package I have. I am using the command ls

~/ariac_ws/src$ ls

ariac CMakeLists.txt gazebo_ros_pkgs universal_robot

I am using the next command line to see if all is well, and not error was reported

~/ariac_ws$ catkin_make install

After that I run the next command line to see on gazebo the cell.

$rosrun osrf_gear gear.py -f catkin_find --share osrf_gear/config/sample.yaml

It open perfectly the cell

the problem that I have is when I want to move the arm, because I cant see the topic

/ariac/joint_states

I dont know which step is missing

Please if some one know how to show that topic.

I use this line recently to fix the error launch node; robot_state_publisher/robot_state_publisher using the next code line

~$ sudo apt-get install ros-kinetic-robot-state-publisher

but still some errors

[Netzahualcoyotl Guadarrama]

Ok the problem was solved using the next command line

~$ sudo apt-get install ros-kinetic-ros-controllers

Glad you were able to get it resolved. While this step is listed in the installation instructions, it's easy to miss. I moved it higher up for visibility.
