A Comparison of Bayesian Prediction Techniques for Mobile Robot Trajectory Tracking
🤖 AI Summary
This study addresses the performance trade-offs among mainstream Bayesian prediction methods—specifically the Extended Kalman Filter, Unscented Kalman Filter, Particle Filter, and Gaussian Mixture Sigma-Point Particle Filter—in the context of mobile robot trajectory tracking, with respect to accuracy, computational cost, and robustness to non-Gaussian noise. Through comprehensive experiments conducted in real-world multi-robot trajectory tracking scenarios, the work quantitatively evaluates each algorithm’s predictive error, computational efficiency, and resilience under challenging noise conditions. The findings not only delineate the operational boundaries and relative strengths of these approaches but also offer clear, practical guidance for selecting appropriate Bayesian filters in real-world robotic applications, thereby delivering significant engineering value.

📝 Abstract
This paper presents a performance comparison of different estimation and prediction techniques applied to the problem of tracking multiple robots. The main performance criteria are the magnitude of the estimation or prediction error, the computational effort and the robustness of each method to non-Gaussian noise. Among the different techniques compared are the well known Kalman filters and their different variants (e.g. extended and unscented), and the more recent techniques relying on Sequential Monte Carlo Sampling methods, such as particle filters and Gaussian Mixture Sigma Point Particle Filter.
