BipedalLocomotion::Estimators::RobotDynamicsEstimator::AccelerometerMeasurementDynamics class
#include <BipedalLocomotion/RobotDynamicsEstimator/AccelerometerMeasurementDynamics.h>

The AccelerometerMeasurementDynamics class is a concrete implementation of the Dynamics.

Please use this element if you want to use the model dynamics of an accelerometer defined, using the kinematics, as the time derivative of the frame linear velocity:

\[ v = J \nu \]

The AccelerometerMeasurementDynamics represents the following equation in the continuous time:

\[ \dot{v}^{accelerometer} = \dot{J} \nu + J \dot{\nu} = \dot{J} \nu + J^{base} \dot{v}^{base} + J^{joints} \ddot{s} \]

where the joint acceleration is given by the forward dynamics equation.
