I have deleted __init__.pyc file and reinstalled the python-catkin-pkg and the templates aren't found yet. The content directory is still the same: /usr/lib/pymodules/python2.7/catkin_pkg/__init__.pyc

The version of the catkin_pkg is 0.1.20

I have created the workspace following the tutorial of creating a catkin workspace and I have set up the shell environment properly, but the templates aren't found.

I'm trying to create a new package in my workspace with catkin_create_pkg and I get this error:

afgonzalez@afgonzalez-desktop:~/ros_workspace/src$ catkin_create_pkg 
  Traceback (most recent call last):

  from catkin_pkg.package_templates import create_package_files, PackageTemplate

  ImportError: No module named catkin_pkg.package_templates</div>

I have reinstalled ros-groovy-catkin and python-catkin-pkg package but the error still there.

Until now we have been doing speech synthesis via festival. The main reason of buying a Verbio licence is that we need some language that Festival doesn't support.

2013-06-14 00:52:27 -0600 answered a question Communication problems with a server

The ros node is very simple, because firstly I only want to test the testdemo in ros environment. The first sentences of the node are those:

if (argc>1)
text = argv[1];
if (argc>2)
vox_setparm(-1, VXGB_DEFSERVER, argv[2]);

ros::init(argc, argv, "tekniker_tts");

printf("Inicializando ... \n");

vox_tts_init(0, "es");

After vox_tts_init call the software stucks on.

I have linked the SDK library to the node adding to the CMakeList.txt file those lines:

rosbuild_add_executable(tekniker_tts src/tekniker_tts.cpp)

target_link_libraries(tekniker_tts voxlib)

Thanks

Dear all,

I need to communicate with a server that is running on my local machine. It is a Verbio TTS server and I have a SDK library which includes all the required functionalities.

When I generate a C++ application where the communication with the server is established and some operation are made, it works well; however, when I create a ROS node with the same code, it compiles well but at runtime the software crashes upon initiating communication.

The ROS node is very simple, because I only want to test the testdemo in a ROS environment. Here are the first few lines of the node:

if (argc>1)

  text = argv[1];

if (argc>2)

  vox_setparm(-1, VXGB_DEFSERVER, argv[2]);

ros::init(argc, argv, "tekniker_tts");

printf("Initializing... \n");

vox_tts_init(0, "es");

After the vox_tts_init call the software crashes.

I have linked the SDK library to the node by adding these lines to the CMakeList.txt file:

rosbuild_add_executable(tekniker_tts src/tekniker_tts.cpp)

target_link_libraries(tekniker_tts voxlib)

Does anyone know how I can solve this problem?

The communication between client and server is established through ports 8764 and 8765. Could it be a problem on ROS environment?

Thanks in advance

2013-04-02 00:16:44 -0600 asked a question Trajectory execution and environment monitoring

Dear all,

We are working in Electric with arm-navigation stack and we would like to know if once the planned trajectory has been sent to execution, an environment monitoring is made. We are worried as the robot surrounding is highly dynamic (the environment changes) and a collision can happen as new objects appear in the planned path. Does the environment server (or any other module of arm-navigation) check for possible collisions during path execution? Or must we check the collision map to detect those possible situations?

On the other hand, we have read that MoveIt! in Groovy implements this path execution checking. Is it a new addition to the arm navigation module?

Thanks in advance,

Ane Fernandez

2012-12-10 00:10:49 -0600 asked a question Move arm: cannot get accurate joint position in simulation

Hello,

We are working using a Robotnik modular arm. We have defined the model of the robot using URDF files but we are having problems in simulation using Gazebo:

-We cannot get accurate joint position in one of the joints, specifically on the second one (error of 0.01 while in the rest the error is of 0.001 or less). -When we use Move_arm in the real robot we get errors of 0.001 or less, acceptable for our needs. -Initially we thought that the problem comes from the joint trajectory controller as it is which sends the control messages to each joint but we have tested it with PR2 and it reaches the desired positions accurately. -We have tried to solve the problem tunning the parameters of the PID but we don't know if it is the problem and how to tune them.

Has anyone had this problem?

Thanks

2012-11-29 01:54:20 -0600 asked a question make_plan service call fail

Hi everyone,

When I call to make_plan service of move_base node I get this error:

move_base must be in an inactive state to make a plan for an external user

I've checked that when I execute call() function, move_base is in Active mode. After that the action that is being executed is canceled, it passes to the preempted state. I suppose at that state it could be possible to make a call so I wait calling periodically to exists() service method to check if the service is both advertised and available.

I don't get it working well, so I would like to know what I'm doing wrong or if there is another way to check service's availability.

Thanks
