RotAxis and TransAxis support in PyKDL?

Hi,

I'm trying to create a parser which can create PyKDL chains out of urdf models.

I just stumbled with my first big issue, which is that PyKDL does not support RotAxis and TransAxis joints. Are there any plans to include support for those?

I can temporarily work around this issue by creating intermediate segments with tip frames with some of its main axes aligned with the joint axis, but this is not a very nice solution.

Best regards, Miguel.

RotAxis and TransAxis support in PyKDL?

I more or less completed the python support for most of the basic classes
(not the solvers yet), I pushed it on the master branch at
git.mech.kuleuven.be/robotics/orocos_kinematics_dynamics.git

It's not fully tested but I do not expect big problems. If there is still
stuff missing you would need. Do not hesitate to contact us again.

RotAxis and TransAxis support in PyKDL?

Hi Ruben,

I've finally managed to get enough time to implement the parser and so far
it looks like the RotAxis joint type is working great.

I'll now start playing around with IK algorithms and put it into greater
stress. If I find anything broken I'll let you know.

Thanks a lot for your help!

Miguel.
