Odom and IMU
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?
