/camera/rgb/image_raw missing

Course Support Deep Learning for Robotics

When executing rosrun get_images get_image_camera.py the program starts and stays idle after loading the CNN model. I could not find the topic to which the class subscribes to. see below:

$user:~/catkin_ws$ source devel/setup.bash
$user:~/catkin_ws$ rostopic list
/clock
/cmd_vel
/gazebo/link_states
/gazebo/model_states
/gazebo/parameter_descriptions
/gazebo/parameter_updates
/gazebo/set_link_state
/gazebo/set_model_state
/imu
/joint_states
/odom
/rosout
/rosout_agg
/scan
/tf
/tf_static
$user:~/catkin_ws$ ros2 topic list
/parameter_events
/rosout

I suspect that since the topic is not being published, the code just stays idle waiting for a callback which never arrives.

Any ideas on how to get to receive messages from the /camera/rgb/image_raw topic?

Hi,

It seems there is an issue in the simulations camera. We will see into it and fix it asap.
Sorry for the inconvenience

Thank you very much, please notify us when that is done.

For now, should I skip the exercise and go to the final project, or will that not work either?

I’m afraid that the only camera working is the over the top camera, the one in the robot is not working. This course needs an urgent remake, Hope to have it done asap

Sorry for the inconvenience
