KD-RIEKF: Kinodynamic Right-Invariant EKF for Legged Robot State Estimation

Qi Yang, Bin Lan, Bingjie Chen, Jingjing Wang et autres

We present KD-RIEKF, a novel state estimation framework that incorporates kinodynamic constraints into the Right-Invariant Extended Kalman Filter (RIEKF). Our framework integrates generalized momentum-based contact estimation, centroidal dynamics, and a noise-adaptive module, improving state estimation accuracy by probabilistically adjusting propagation noise to …
