I am really beating my head hard over this, excuse me while I ask a silly question.

I'm building my own robot using HCSR04 as range sensors and a MPU925 as an IMU, while going through the navigation package, I got really confused with the difference between data/imu and nav_msg/Odometry. How are the related and what do I need to go to get localization working?

Can you be more specific? What does confuse you? And what does the range sensor have to do with odometry in this context?

How are you connecting your IMU to your roscore ? There is github with relevant code if you are using a raspberry/beaglebone: https://github.com/vmayoral/bb_mpu9150

If you are using an arduino, then use rosserial and get the data with ROS from there: http://wiki.ros.org/rosserial_arduino...
