fourth_robot.urdf.xacro が読めない

[MoriKen254]

取り急ぎ。

推定原因

確かxacroの文法がKineticで若干変更になったはず。Indigoに合わせて記述したfource_robotがそれに適合できていないと思われる。

コマンド

roslaunch fourth_robot_description fourth_robot_description.launch

それはそこに書かれている通りのコマンドを実行すれば解決します find . -iname "*.xacro" | xargs sed -i 's#<\([/]\?\)\(if\|unless\|include\|arg\|property\|macro\|insert_block\)#<\1xacro:\2#g'
