Oct 26th update:

Problems: 1. odometry orientation does not changes. 2. warning messages when running dual_ekf_navsat_example.launch

commands that I run on the master (laptop):

roscore

roslaunch turtlebot3_navigation turtlebot3_navigation.launch map_file:=/home/yuxiang/Desktop/Robot/empty_map.yaml
roslaunch robot_localization dual_ekf_navsat_example.launch predict_to_current_time_:=true

commands that I run on the turtlebot3 (remote):

roslaunch turtlebot3_bringup turtlebot3_robot.launch
roslaunch ros_imu_bno055 imu.launch serial_port:=/dev/ttyUSB1 operation_mode:=NDOF_FMC_OFF use_magnetometer:=True
rosrun nmea_navsat_driver nmea_serial_driver _port:=/dev/ttyUSB2 _baud:=9600

I have also modified the turtlebot controller code where I disabled its original IMU: https://github.com/AutoPlow/TurtleBot...

Your suggestions would be much appreciated!
