opencog / blender_api_msgs

ROS node for blender_api

blender_api_msgs

ROS interface controlling the head+body blender_api rig.

Design goals

• Avoids adding ROS code to the blender_api python module
• Eliminates the need for other ROS nodes from having to import the blender_api python module.

Installation

$ cd your_catkin_workspace/src
$ git clone https://github.com/opencog/blender_api_msgs.git
$ pip3 install -t ../devel/lib/python2.7/dist-packages/ ./blender_api_msgs
$ cd ../
$ catkin build

The the above uses several hacks which may be painful to discover and diagnose. These are:

• Neither catkin_make nor catkin build currently support entry_points in setup.py. To be more precise, it is actually catkin_pkg.python_setup that does not support entry_points, and thus ordinary python setup is used, instead of the catkinized version.

• Next, pip3 install defaults to an install path in the root file system. To work around this, an explicit install path must be specified with the -t flag.

• You might think that the correct catkin install path would be in python3.4 not python2.7 but you would be wrong: when sourcing devel/setup.sh, only the 2.7 path is added to PYTHONPATH.

Usage

Start blender from the /blender_api project. If this package was installed with pip or setuptools, blender_api should discover it automatically.

Blender can be started with the autostart script:

blender -y Sophia.blend -P autostart.py

or it can be started manually, by pressing the Start Command Listener button.
