I've maybe found an example but he is not working :
rostopic pub /submarine/thrusters/0/thrust_wrench geometry/WrenchStamped "header:
seq: 0
stamp:
secs: 0
nsecs: 0
frame_id=''
wrench:
force:
x: value
y: value
z: value
torque:
x: value
y: value
z: value"
But this error appears :
/opt/melodic/lib/python2.7/dist-packages/rostopic/init.py:1782: TAMLLoad Warning: calling yaml.load() without Loader=... is deprecated, as the default to Loader is unsafe. Please read https://msg.pyyaml.org/load for full details. pub_args.append(yaml.load(arg)) publishing and latching message.
https://github.com/yaml/pyyaml/wiki/PyYAML-yaml.load(input)-Deprecation
A solution is available on this link, but doesn't work on my machine ...
Is my example wrong ? Or there is a bug ?
If not, apparently, you should specify the Loader argument into the load() function like this :
yaml.load(input, Loader=yaml.FullLoader)
(More details are on the link)
EDIT :
You have to change the file where the error occurs, in my case I had to change the init.py file, I just converted the function yaml.load() by yaml.safe_load() and after it is possible to publish into the topic ROBOT_NAMESPACE>/thruster_manager/input but the submarine is still not moving ...
I am also confused by the end of this tutorial, have you made any progress? Thanks!
Hello @EmmaShou, I've find a solution, you can check my project https://github.com/TheGreatLebowski/submarine, I've write a simple documentation (Still in progress) where I've put some of the problem I got ! If you don't find what is your problem send me a message, maybe I can help you !
Hi Alexandre,
Thank you -- that's really helpful! Can I ask you another question? Have you been able to make your submarine either follow way-points or move according to a function? There are UUV simulator tutorials about this but I'm having a difficult time getting those tutorials to work.
Thanks a ton, Emma

Hi Emma ! No I am currently working on it, when I will find a solution I will add it in my github project, but if you find something please let me know !
Thanks Alexandre!

@TheGreatLebowski Nice, could you, please create a PR with your new documentation? It would be very helpful to have your colaboration!
Thanks!
Hello,
In the section Configuring the thruster manager of the tutorial, it is written at the end
Can you add an example ? And also I don't understand where I should put the command ...
Thank you for your help !
