-Nicer demos:
-
-
-circle.bag: flat circle in Z plane, IMU NOT biased
-
-circleXYZ.bag: bended circle with sinusoidal deviation in 3 directions, IMU NOT biased
-
-everything: alike circleXYZ with orientation changes and IMU noise, IMU biased on all axis
-
-everythingBiasedX: alike everything with orientation changes and IMU noise, IMU biased on X axis
