Velocity Motion Model

Odometry Motion Model, Motion Model With Maps

The velocity motion model assumes that the robot is controlled through 2 velocities: rotational and translational velocity:

ut=(vt ωt)

A sampling algorithm generates a random pose according to the distribution p(xt|ut,xt1), and perturbs it with the noise, drawn from the error parameters of the kinematic motion model.

(v^ ω^)=(v ω)+(εα1|v|+α2|ω| εα3|v|+α4|ω|)
