ND013 M4 L3 02 L Localization Posterior
Formal Definition of Variables
z_{1:t} represents the observation vector from time 0 to t (range measurements, bearing, images, etc.).
u_{1:t} represents the control vector from time 0 to t (yaw/pitch/roll rates and velocities).
m represents the map (grid maps, feature maps, landmarks)
x_t represents the pose (position (x,y) + orientation \theta )
