Improvements:

  • Re-organized launch files:
    • IMU related launch files were shifted to launch/imu
    • minimal.launch is now used for running the robot without laser driver
    • launching of laser driver on navigate and slam launch files was shifted to bringup.launch (for simulation purposes)
    • created include folder so as to only expose 4 major launch files
