"""
Odometry-based motion model (Probabilistic Robotics style)
Implements:
- motion_model_odometry(xp, x, u, alphas) -> likelihood p(x' | u, x)
- sample_motion_model_odometry(u, x, alphas, n) -> samples x' ~ p(x'|u,x)
- odom_from_poses(xp, x) -> (Δrot1, Δtrans, Δrot2) from two poses

modelo del sensor basado en haz de luz y likelihood field, tema 2.3
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
"""
Beam range sensor — Beam Model + Likelihood Field Model (LFM)
- First: show the simulated occupancy map and raycasting result (z_exp).
- Second: plot the BEAM model mixture components and total (continuous + stem at z_max).
- Third: implement and plot the Likelihood Field Model curve p(z | x, m) for the same beam.
(Also display the distance field heatmap for intuition).
