The robot will not directly measure X unfortunately, but the robot may observe portions of X through it's sensors. this portion is labeled Z, where the relationship between the State and measurement is given by the mixing matrix, C.
Creditly both X and Z contain noise even in this model.
State X is noisy because the linear model does not capture all
Physical interactions.
Observation Z are noisy because sensors contain noise in their measurements.
