@k-okada with this PR, Fetch speaks who is running the app in time_signal, tweet and battery_speak apps.

Is this program running on Fetch15 or Fetch1075?
I cannot find /app_manager/running_user_name by rostopic list and by rosparam list...

[knorth55]

it is on fetch15.
can you run tweet app from rwt_app_chooser?
in that time, you are asked to fill your user name in rwt_app_chooser, and fetch15 will say something before starting tweet app.

detailed info: tork-a/visualization_rwt#95

Thank you! I understand.
I think this is very nice feature.

Could you add usage or documentation to README.md?

[knorth55]

what kind of readme do you want?
readme of rwt_app_chooser?
but if user uses rwt_app_chooser normally, they will be asked to fill user name.

Sorry, I think it is better to write below contents to jsk_fetch_startup/README.md (https://github.com/jsk-ros-pkg/jsk_robot/blob/master/jsk_fetch_robot/jsk_fetch_startup/README.md)

• First, we can register user name for app running.
• We can start apps with empty string, but /app_manager/running_user_name param will not be set.
• Then, we can run an app.
• By username, if one person is using fetch, others cannot use fetch.

@708yamaguchi I have a plan to add user_warning node, which the robot alert someone is moving the robot with no running_user_name next.
In that time, I will write down the documentation for JSK robot Personal Use app for PR2 and Fetch.

[708yamaguchi]

Thank you for your explanation.
I understand.
Sorry for late reply.
