Model conversion in RTM-ROS system

Conversion overview


rtmros_common provides functionality for converting VRML model files into COLLADA, Euslisp, and URDF model files.

- export-collada in the openhrp3 package performs VRML => COLLADA conversion.

- The euscollada package provides COLLADA => Euslisp conversion.

Converting VRML files to Euslisp files

Change directory into your catkin workspace source folder:

cd ~/catkin_ws/src

Create a new package for converting VRML files into Euslisp files. Our package will depend on the hrpsys_ros_bridge package:

catkin_create_pkg robot_model_converter hrpsys_ros_bridge

Create a models folder in our package to hold our robot model files:

cd robot_model_converter 
mkdir models

Copy your robot VRML file and YAML file into the models folder:

cp <robot VRML file> models/robot.wrl
cp <robot YAML file> models/MyRobot.yaml

Edit the CMakeList.txt to include the following line:

compile_openhrp_model(${PROJECT_SOURCE_DIR}/models/robot.wrl MyRobot)

Now we're ready to make the package:

cd ~/catkin_ws

If you inspect the model folder, you will find a set of files generated, including the myrobot.l Euslisp file converted from the VRML file.

The Euslisp file can then be loaded by executing:

cd ~/catkin_ws/src/robot_model_converter/models
rosrun roseus roseus myrobot.l
> myrobot
> objects *myrobot*
