sdf转urdf

GitHub - andreasBihlmaier/pysdf: Python library to parse SDF into class hierarchy and export URDF
目前执行成功的是ubuntu18.04 python2

mkdir -p catkin_ws/src
cd catkin_ws/src
git clone https://github.com/andreasBihlmaier/pysdf
pip install .
mkdir build && cmake .. && sudo make install
cd ../../
catkin_make

执行成功效果：

/pysdf/scripts$ python sdf2urdf.py [-p plotfile.png] model.sdf model.urdf

检查urdf合法性：?

sudo apt-get install liburdfdom-tools
check_urdf model.rudf
