2013-08-01 23:59:54 -0500 asked a question does the gmapping package works on arm processor?

I managed to build and launch the gmapping package (ros-fuerte-slam-gmapping) successfully on one of my embedded system (intel processor). It seems that it works fine. However when I copied the package over to another embedded system (arm processor), I got lots of errors trying to build it. So can I actually run the gmapping package on the arm processor?

2013-07-25 00:59:18 -0500 asked a question SDL image error while building gmapping

While building the gmapping package in my embedded system (odroid-x), i got this error:

Building CXX object CMakeFiles/image_loader.dir/src/image_loader.o /home/linaro/ros/navigation/map_server/src/image_loader.cpp:43:27: fatal error: SDL/SDL_image.h: No such file or directory

It seems that I do not have the SDL_image.h file. If i download the file, where go i have to place it in? However it run just fine in my laptop. Can anyone tell me whats the problem? Thanks!

Alright thanks! I'll have to read more about the tf then! :)

2013-07-15 21:41:51 -0500 asked a question how does the odometry (imu+encoder) publish its data to gmapping?

I am able to get my odometry working (with IMU and encoders readings). But how do i actually publish the relevant data to gmapping? Is the gmapping file actually subscribing any data from the odometry?

2013-07-11 20:44:13 -0500 asked a question How does gmapping uses odometry data (from the encoder + IMU)

Hi everyone, I'm currently working on a robotics project which uses gmapping. If I'm not wrong, the gmapping uses information from odometry and laser to obtain more accurate results. But how does the IMU and encoder data is used in this case? Any help is appreciated :)
