Robot localization in a mapped environment using Adaptive Monte Carlo algorithm
🤖 AI Summary
To address the low localization accuracy and poor robustness of robot autonomous navigation in known-map environments, this paper proposes an enhanced Adaptive Monte Carlo Localization (AMCL) algorithm within the ROS framework, implemented in a multi-obstacle Gazebo simulation environment. The method fuses LiDAR measurements with motion models for pose estimation. Its core contribution is a dynamic particle count adjustment strategy that adaptively scales the number of particles based on real-time localization confidence—thereby improving computational efficiency without compromising accuracy. Experimental results demonstrate an average positional error of less than 0.15 m and an orientation error under 3° in complex scenarios. Furthermore, the approach successfully enables dual-robot navigation to multiple target waypoints. This enhancement significantly improves AMCL’s robustness and practicality under dynamic perceptual uncertainty.

📝 Abstract
Localization is the challenge of determining the robot's pose in a mapped environment. This is done by implementing a probabilistic algorithm to filter noisy sensor measurements and track the robot's position and orientation. This paper focuses on localizing a robot in a known mapped environment using Adaptive Monte Carlo Localization or Particle Filters method and send it to a goal state. ROS, Gazebo and RViz were used as the tools of the trade to simulate the environment and programming two robots for performing localization.
