I had the same problem. I have delete the class UnizarRoboEarthInterface.java After that, the re_comm package compiles. Best Regards Florian

Hi folks,

I want to create an action recipe with the aid of the KnowRob Recipe Editor and upload them to the RoboEarthd database. If I try to push the button: “Save recipe to RoboEarth” I get the following Prolog exception:

jpl.PrologException: PrologException: error(existence_error(procedure, /(re_submit_action_recipe, 4)),
context(:(system, /(call, 1)), _2015))

I am using ROS-fuerte, Ubuntu 12.04, SWI-Prolog version 5.10.4, the latest KnowRob Stack as well as the newest KnowRob_gui stack.

Thanks for every helping hand :)

HI,

do you have a solution for the problem? I have the problem as well. By building the stack knowrob_gui the following error occurs:

stacks/knowrob_gui/src/jp/atr/unr/pf/gui/KnowRobGuiApplet.java:276: cannot find symbol symbol : method getController() location: class controlP5.ControlEvent if(theEvent.getController().getName().equals("save recipe to roboearth"))

stacks/knowrob_gui/src/jp/atr/unr/pf/gui/KnowRobGuiApplet.java:300: cannot find symbol symbol : method getController() location: class controlP5.ControlEvent if(theEvent.getController().getName().equals("save recipe to file")) {

stacks/knowrob_gui/src/jp/atr/unr/pf/gui/KnowRobGuiApplet.java:379: void cannot be dereferenced .setUpdateMode(ControlWindow.NORMAL)

stacks/knowrob_gui/src/jp/atr/unr/pf/gui/KnowRobGuiApplet.java:383: cannot find symbol symbol : method getController(java.lang.String) location: class controlP5.ControlP5 if(controlP5.getController("notification")==null) 100 errors

Thanks for help.

Hi folk,

I am using the current Nao-ROS stack (fuerte). I want to control the Nao in an abstract way. Now, I am trying to send commands to the nao_controller to move the left arm from the Nao. I found only one option to do this. Namely to create a JointTrajectory message for the left arm and this message as goal to the ActionServer of the nao_controller. This message requires to define 6 radians for each joint of the left arm: (LShoulderPitch,LShoulderRoll,LElbowYaw,LElbowRoll,LWristYaw2,LHand2)

But, I don`t want to control the joints seperately. I want to say: moveLeftArmToPosition (x,y,z) So, do I have to solve this mapping on my own, or, has the nao_driver this task already done?

I want to ask as well, if the nao_driver provides a node to start face detection. I havn`t found it in the documentation. Thanks a lot.

Best Regards

Florian

Hi everybody,

my name is Florian from the HAW Hamburg. I am still writing my Masterthesis about knowledge sharing for robots....especially for the NAO robot from Aldebaran robotics. So...my thesis deals with the connection between RoboEarth and NAO. The target is, that serveral NAO`s can exchange executable action recipes among eachother to improve their learning mechanism. Also...i am now developing an interface between NAO and RoboEarth via the ROS-Middleware. My problem is that, i can´t translate any CRAM-action-recipes into physical low-level routines from the NAO robot. So i can´t execute the CRAM-action-receipe on the NAO. In the paper "RoboEarth Action Recipe Execution" i have read, that i can access the robot hardware routines over process modules and actionlib libary from ROS. So....what should i do to handle that problem...to execute CRAM-action recipes on the NAO robot? Must i implement my own process modules for the NAO?

Thanks :)

Kind regards
