A High-Precision Odometry Calibration Method for Mecanum-Wheeled Mobile Robots Based on ZUPT and Closed-Loop Pose Estimation
This study presents a two-level closed-loop calibration framework that combines L2-norm displacement feedback, normalized angular increment integration, relay control with a tolerance deadband, and zero-velocity-based adaptive covariance switching that can reduce both motion-dependent odometry scale errors and stationa...
