Miscellaneus to-do list #12

@jlblancoc in mvsim/definitions/imu.sensor.xml, including noise on the random walk of the imu (similar to how hector_gazebo_plugins does via params accelDrift and rateDrift) would be a good feature to add for a future release. The revised params in imu.sensor.xml could be revised to:

<angular_velocity_white_noise_std_noise> ... </angular_velocity_white_noise_std_noise>
<linear_acceleration_white_noise_std_noise> ... </linear_acceleration_white_noise_std_noise>
<angular_velocity_random_walk_std_noise> ... </angular_velocity_random_walk_std_noise>
<linear_acceleration_random_walk__std_noise> ... </linear_acceleration_random_walk__std_noise>

Simulations can then represent the IMU model presented in:

Thanks for the pointer @adthoms .

Sure, the current IMU is just a very basic type without realistic noise. I had the seminar paper in the radar for another project but didn't have at hand a reference plugin implementation, so it's welcome!

It will be even more useful when adding drones (future wish list...) ;-) (cc: @FranciscoJManasAlvarez )
