Hi, I am very interested in know if anyone knows how to run the floor collision map demo in the ucsb-ros-pkg as seen here in their google docs video. I have downloaded and ran all the other examples in the ucsb package and have even moded it to work with a wii Remote, but cannot find the floor mapping code in the package.

http://code.google.com/p/ucsb-ros-pkg/

Thanks, -Scott

Hi,

I'm the creator of that demo, so I should be able to help you out. I haven't uploaded the code to our public svn because it could do with a little updating to clean up the code, split off sections into functions, etc. It also doesn't compile under electric because it was developed under cturtle and I haven't updated it.

This demo was mostly created for me to learn PCL, so there are lots of ways to improve the code. For example, using kd trees instead of brute force collision detection, etc.

That said, here's the source code if you want to take a look.

//planar segmentation, with a collision detection function.
//Publishes several ros topics with intermediate data for debugging
//and illustrative purposes.
