Does anyone have an example of using a gyroscope (or other rotation sensor) to drive the estimation of a quaternion in the state? I understand that a quaternion has issues with the covariance due to …

Note to self:
Had to disable TMBad framework for easy access to "erf", but then mean estimation not supported, lacking support to newton::cfg. Disabled newton::cfg for both ekf and ukf.

Hello,
I like your UKF code
Are you using

to translate logic to C# ?
Could you provide som…

I don't know if there's more direct way to apply `em` algorithm for nonlinear cases, i.e. `UnscentedKalmanFilter` and `AdditiveUnscentedKalmanFilter`. Though, I think `filter` and `smoother` actually …

Research Extended Kalman Filter (EKF) and Unscented Kalman Filter (UKF).
-Implement either approach using the robot_localization package
