To: Ruben Smits <Ruben Smits [..] >

Hi Ruben,
great job with orocos and kdl in particular.
One quick question: I'm able to compile kdl 1.0.2 with python bindings
on my mac, and a PyKDL.dylib is created inside the usual site-packages
folder.
However, when I do an import PyKDL, it cannot find the library. Click below to read the rest of this post.

Hey,

Below is my question about the ChainIkSolverPos_NR class. I'm not sure if
it's clear....if not I'll try to explain it again more clearly.

In my chain I have segments A,B,C,D,E. (I'm using CartToJnt (const JntArray
&q_init, const Frame &p_in, JntArray &q_out))

I want to be able to solve for an IK solution for a pose of 'E' in frame 'A'
and allow the solver to search for a solution but without using joint 'A'. I
want it to search for a solution by just changing the joint angles
corresponding to B,C,D,E in q_init. Click below to read the rest of this post.

Given it's a beta, and some major features are lacking, it's still great stuff.
Until now, development of the 2.0 mainline had two major focusses: API
usability and providing an upgrade path for existing users. The first one
required major API changes, the second one conversion scripts.

This beta release allows you to check most 'C++' and 'scripting' aspects of
2.0 and allows you to grasp a first 'look-and-feel' of what RTT 2.0 offers.
Following beta releases (1.99.x) will expose the improved CORBA transport and
data type generation. Click below to read the rest of this post.

In a discussion on the LWR mailing list, an issue related to the fosi.h file using Xenomai came up, see the messages below. Does anyone have an idea what might be going wrong?

Hi Wilm.

I installed eigen ($ rosmake eigen), and still could not compile the kdl-1.0 package. Click below to read the rest of this post.

Hi,

I'm trying to compile RTT for a Linux-rt preempt kernel and want to
point the build-system to the right linux-headers, but cmake seems to
not pick up my LINUX_SOURCE_DIR definition:

I execute cmake as follows:

cd rtt-svn/build && cmake -DCMAKE_INSTALL_PREFIX=`rospack find
rtt-1.10`/rtt/ -DOROCOS_TARGET=gnulinux -DCMAKE_PREFIX_PATH=
-DCMAKE_BUILD_TYPE="RTT" -DCORBA_IMPLEMENTATION="OMNIORB"
-DENABLE_CORBA=ON
-DLINUX_SOURCE_DIR=/usr/src/linux-headers-2.6.28-3-rt ..

but make VERBOSE does not show the include path to my kernel headers:

Hi Falks,

The app I am developing is fully dependent on StateMachine
implementation: my root state machine controls the autonomous mission of
my robot, executing sub state machines depending on my robot's state.

The pb I encounters is that I have to define all my state machines (root
and subs) on the same osd file, while it would be really great for me to
define sub machines in independent files (usefull for unit testing and
of course reusability).

As anyone an idea on how to do that we the current 1.10 Orocos scripting
service?

Could this feature be added to the next (... Click below to read the rest of this post.

I used successfully in my components a couple of Methods that return user
defined types. Click below to read the rest of this post.

Hi,

we are upgrading our server where the orocos bugzilla is installed.
Expect some downtime anywhere between tonight and tomorrow night :-)

Best regards,

I try to extend the std::array type but i can't compile.

With my others structs i haven't the problem.

I tried to read the sources of rtt for std::vectors, but i can't find the solution.

I join a simple file that reproduce the problem.

Could you help me to understand what happens please ?

The Orocos development team is pleased to announce the second bug fix release of the Kinematics and Dynamics library v1.0, a C++ library for 6D geometry calculations, building kinematics and dynamic models and doing inverse and forward calculations in a real-time context.

A lot of bugs have been reported and fixed. Upgrading is recommended if you use the python-bindings, cmake 2.8 and the inverse velocity solvers.
