Hi all!

I've finished my project in University, and now I want to do some tests.

For example, in each iteration of the component, I want to know what the running time exactly (the period is 0.01 seconds, but the running time should be less).

Is there any function within the Orocos library to measure that time? Can I use clock() function in c++, or is there another more accurate?

Thank you very much.

Jose

PS: Soon I will upload a video of my parallel robot 3DOF PRS with all the control implemented by Orocos (with Xenomai).

Hey,

I am seeing strange behaviour of the Reporter component. Click below to read the rest of this post.

Hi all,

I'm trying to using complex data types with Corba but till now it doesn't work.

I tried to use typegen. It seams work and it generates a typekit folder with some cpp files, the corba IDL, and so on. Click below to read the rest of this post.

Based on the Orocos Toolchain v2.4.0, this release fixes the 'type mismatch' issue for Ubuntu Lucid users. Also other small fixes for the Orocos-ROS integration have been applied, such as a cmake problem when generating typekits and generating a correct header file name in the typekit/ subdirectory. This project is available on http://www.ros.org/wiki/orocos_toolchain_ros

Hi,

I just wanted to compile my own soem drivers but I get an error when compiling. The drivers worked before and I did not change anything to the drivers. Click below to read the rest of this post.

Hey,

I have two (related) problems, two things that used to work fine: When I start the Reporter to report a specific port that contains an existing ros-msg, I get the following error continuously:

15.569 [ ERROR  ][Master] Failed to build 'Property</geometry_msgs/Vector3> Theta' from given DataSourceBase. Returning default.
15.569 [ ERROR  ][Master] Failed to build 'Property<float64> x' from given DataSourceBase. Returning default.
15.569 [ ERROR  ][Master] Failed to build 'Property<float64> y' from given DataSourceBase. Click below to read the rest of this post.

Hello!

I am having a problem with my deployer. Every time I start it (even without loading any component) and I type ls, the deployer crashes with a segmentation fault.

Here is the output of the terminal when I start the deployer:

ferraraf@ferraraf-desktop:/home$ deployer-gnulinux -linfo
0.000 [ Info   ][Logger] Real-time memory: 14096 bytes free of 20480 allocated.

Hey,

I am having trouble when streaming an OrocosPort to ROS. Very often I get the following message:

Deployer [S]> 7.884 [ ERROR ][Master] A channel of port Joint_pos_port has been invalidated during write(), it will be removed

After this, the associated rostopic is still there but rostopic echo or rxplot doesn't do anything anymore. Click below to read the rest of this post.

Hi all,

I'm working with the exercise 5 and I'm trying to define the provided and required services in two classes which implement the interfaces Service and ServiceRequester.

I also defined two components that implement the my own classes.

Now the problem is that when I launch the application I can not see the services in the task browser. Both, the hello and the world components have no services. Click below to read the rest of this post.

since I updated to the latest orocos-toolchain I can no more load components which are linked against opencv. Do you know what this issue may cause?
