Robust state estimation is critical for enabling reliable autonomous robot operations in challenging environments. To estimate the state, heterogeneous sensor fusion is commonly employed to enhance the reliability against perceptual failure. However, most known methods for sensor-fusion are brittle to dynamic perceptual condition changes due to the use of hand-tuned and time-constant error models. This paper introduces ROSE, a Robust Online-adaptive State Estimator, capable of adapting uncertainty statistics for individual multi-modal estimates in real-time to perform reliable sensor-fusion for robot state estimation. The proposed method leverages theory from adaptive Kalman filtering and extends it to optimization-based methods, to improve estimation accuracy while enabling integration of delayed heterogeneous sensor inputs. ROSE has been thoroughly evaluated by simulation studies and real-world demonstrations using a high-speed off-road vehicle navigating complex unstructured terrains and performing aggressive motions.
