Can't launch rqt_robot_steering

edit

Hey ROS-Community

I want to controll my Robot in Gazebo and launched Gazebo with the command

gazebo

Everything launched fine and I can place my robot in the world at the panel Insert with the command in the .bashrc file:

export GAZEBO_MODEL_PATH=$GAZEBO_MODEL_PATH:/home/joni/dev_ws/src/basic_mobile_robot/models/

So everything went fine and I can set my robot into the enviroment with Insert. See here:

I opend a new Terminal and wanted to launch rqt_robot_steering and tipped in:

rqt_robot_steering

and the Error output was :

rqt_robot_steering: command not found

The rqt pkg is installed with the command:

 sudo apt-get install ros-humble-rqt

The output was:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
ros-humble-rqt is already the newest version (1.1.4-1jammy.20220909.020555).
0 upgraded, 0 newly installed, 0 to remove and 27 not upgraded.

So i gues the pkg is installed? My enviroment is sourced with the .bashrcfile lines:

source /opt/ros/humble/setup.bash
export ROS_DOMAIN_ID=1
source /usr/share/colcon_cd/function/colcon_cd.sh
export _colcon_cd_root=/opt/ros/humble/

So what´s wrong? If you want to test or see smth in my enviroment please ask.

Thanks for helping!
