openrave_models's Issues

Specify joints

Hi, thanks a lot.
I have my model in blender now, and I can even export it from .wrl to .dae!

But all my joints seems to be independent and when I export I get one solid mesh instead
of robot with dependent joints.

So my question is: how to prepare the model to be exported in to right .dae.
How to specify all joints and constraints?

All joints in my model are going to be rotational, there should be some limits,
but that is kind of optional.

Somehting wrong with my WRL 

In [2]: import openravepy
In [3]: a = openravepy.Environment()
In [4]: a.Load("hmmm.WRL")
Coin read error: Unable to read identifier after DEF keyword
	Occurred at line 2769 in /home/georgy/Downloads/hmmm.WRL
Coin read error: Invalid definition of R
	Occurred at line 2769 in /home/georgy/Downloads/hmmm.WRL
Coin read error: Couldn't read value for field "children" of VRMLTransform
	Occurred at line 2769 in /home/georgy/Downloads/hmmm.WRL

DATA_READ - Fatal error!
  Unacceptable input file type.
2017-07-05 22:15:21,345 openrave [WARN] [environment-core.h:492 Load] load failed on file hmmm.WRL
Out[4]: False

Got this error. Maybe I use some wrong wrl file?
Which version of blender should I use?

Importing and Creating your own model

Hello, here is log, which I got, calling 'python load_model.py Robot.dae' on my simple ".dae" file:

2017-07-04 01:12:14,936 openrave [ERROR] [colladareader.cpp:3788 ColladaReader::handleError] COLLADA error: Trying to load an invalid COLLADA version for this DOM build!

    robot = env.GetRobots()[0]
IndexError: list index out of range

I assume, that I made some wrong ".dae" and maybe you can share some tips how to make right model, which I will be able to use with openrave.
Or I better make urdf/xml?
