xacro issue: unexpected EOF while parsing #47

Closed xwavex closed 8 years ago

xwavex commented 8 years ago

Hi folks, I am trying to launch the latest version of the simulation example: roslaunch --ros-args single_lwr_launch single_lwr.launch Unfortunately, this gives me the following error while parsing the utils.xacro file... unexpected EOF while parsing (<string>, line 1) when evaluating expression 'mass * (3 * radius * radius + length * length) / 12)'

Any ideas how to solve this issue?

Below you can find the full log: Traditional processing is deprecated. Switch to --inorder processing! To check for compatibility of your document, use option --check-order.

In the file utils.xacro are too many closing brackets making this file invalid.
