fail to launch node icubsrv && icub-head on yarpmanager cluster inside the docker

[jimingda]

The prompt message asked me to type icub@icubsrv's password: && icub@icub-head's password: after i launch selected nodes(icubsrv && icub-head) on cluster of yarpmanager, i typed "icub" as password, but it failed, did I type the wrong password?

While i go back outside the docker, directly launch yarpserver, yarpmanager and yarpmotorgui on terminal of ubuntu, it works well.

Hi @jimingda

Simply put, the docker-based system we provide for training is not suitable for being used together with the robot.

Instead, you ought to be using the physical systems connected to the robot made up of the icubsrv machines and the robot itself (i.e., icub-head).

Thanks ugo, and another question is that if i want implement the tutorial_joint-interface in real icub, which part do i need to configure, maybe change optJoint.put("remote","/icubSim/left_arm"); to optJoint.put("remote","/icub/left_arm") is not enough

Actually, that's sufficient to connect to the real robot.
To this aim, remember to leave aside the docker container and build the tutorial on the robot PC.

Thanks, now there is another problem even i change optJoint.put("remote","/icubSim/left_arm"); to optJoint.put("remote","/icub/left_arm") ;
after i build the tutorial, that the Host of Tutorial_on_Joint_Interface_App and Tutorial_on_Joint_Interface_System shows on YARP module manager is still 'localhost', not the icubsrv or icub-head, someplace didn't configure well ?

Hi @jimingda

Probably, you should be learning first the use of yarpmanager.

At any rate, you can always run the executable from the terminal bypassing the manager, which is a thing I suggest you do in the meanwhile.
