Monte Carlo Localization for Mobile Robots
This paper presents a method for mobile robot localization using particle filters (Monte Carlo), which is more flexible and accurate than previous methods like the extended Kalman filter.
The algorithm samples from the robot's state distribution and updates particle weights based on sensor measurements (e.g., laser or camera), estimating the robot's position probabilistically.
The particle filter can handle multi‑modal distributions and outperforms the Kalman filter in real‑world environments with sensor noise.
Computational cost increases with the number of particles; it may diverge in the absence of reliable measurements and requires optimization for large environments.
Monte Carlo Localization (MCL) is used in many service robot and autonomous vehicle navigation systems. In the humanoid service robot project, MCL can accurately estimate the robot's position in home or office environments, aiding path planning.
