DogLegs: Robust Proprioceptive State Estimation for Legged Robots Using Multiple Leg-Mounted IMUs

IROS 2025

Robust and accurate proprioceptive state estimation of the main body is crucial for legged robots to execute tasks in extreme environments where exteroceptive sensors, such as LiDARs and cameras, may become unreliable. In this paper, we propose DogLegs, a state estimation system for legged robots th

MR-ULINS: A Tightly-Coupled UWB-LiDAR-Inertial Estimator With Multi-Epoch Outlier Rejection

RA-L 2024

The LiDAR-inertial odometry (LIO) and the ultra-wideband (UWB) have been integrated to achieve driftless positioning in global navigation satellite system (GNSS)-denied environments. However, the UWB may be affected by systematic range errors (such as the clock drift and the antenna phase center off

FF-LINS: A Consistent Frame-to-Frame Solid-State-LiDAR-Inertial State Estimator

RA-L 2023

Most of the existing LiDAR-inertial navigation systems are based on frame-to-map registrations, leading to inconsistency in state estimation. The newest solid-state LiDAR with a non-repetitive scanning pattern makes it possible to achieve a consistent LiDAR-inertial estimator by employing a frame-to

IC-GVINS: A Robust, Real-Time, INS-Centric GNSS-Visual-Inertial Navigation System

RA-L 2023

Visual navigation systems are susceptible to complex environments, while inertial navigation systems (INS) are not affected by external factors. Hence, we present IC-GVINS, a robust, real-time, INS-centric global navigation satellite system (GNSS)-visual-inertial navigation system to fully utilize t

Wheel-SLAM: Simultaneous Localization and Terrain Mapping Using One Wheel-Mounted IMU

RA-L 2023

A reliable pose estimator robust to environmental disturbances is desirable for mobile robots. To this end, inertial measurement units (IMUs) play an important role because they can perceive the full motion state of the vehicle independently. However, it suffers from accumulative error due to inhere
