Initial commit of Kuka robot based on Model KR210 step file.
The received step file was titled "KR150_180_210_240-2AV400", so these meshes might represent a family of robots, but for now specifically things are set up for the KR210.
There are STL's and dae's in the visual folder because the stl's are oriented "properly" with all z axes going in the world z axis direction, whereas the dae's are rotated 90 degrees. The dae's have color so those are included in the macro.xacro and the urdf with a pi/2 rotation to fix links 2-5 (links 0, 1, and 6 are ok).
Renamed link meshes to be lower-case.
Added subdirectory in meshes for specific type L150
renamed urdf/xacro files to have model and type
Cleanup - used git to remove files in old directory structure.
Corrected spelling error
change case and added model (L150 -> kr210l150) to follow convention
Fixed issues such as white space and capitalization and updated names within files.
Changed link names within macro.xacro to follow lower case and under score conventions.
Changed link 1 and 6 collision stl's to have correct origin.
Merge pull request #3 from gomezc/hydro-devel
