navlie: A Python Package for State Estimation on Lie Groups
Charles Champagne Cossette, Mitchell Cohen, Vassili Korotkine +3
The ability to rapidly test a variety of algorithms for an arbitrary state estimation task is valuable in the prototyping phase of navigation systems. Lie group theory is now mains…
IMU Preintegration for Multi-Robot Systems in the Presence of Bias and Communication Constraints
Mohammed Ayman Shalaby, Charles Champagne Cossette, Jerome Le Ny +1
This document is in supplement to the paper titled "Multi-Robot Relative Pose Estimation and IMU Preintegration Using Passive UWB Transceivers", available at [1]. The purpose of th…
STAR-loc: Dataset for STereo And Range-based localization
Frederike Dümbgen, Mohammed A. Shalaby, Connor Holmes +4
This document contains a detailed description of the STAR-loc dataset. For a quick starting guide please refer to the associated Github repository (https://github.com/utiasASRL/sta…
Magnetic Navigation using Attitude-Invariant Magnetic Field Information for Loop Closure Detection
Natalia Pavlasek, Charles Champagne Cossette, David Roy-Guay +1
Indoor magnetic fields are a combination of Earth's magnetic field and disruptions induced by ferromagnetic objects, such as steel structural components in buildings. As a result o…
Decentralized State Estimation: An Approach using Pseudomeasurements and Preintegration
Charles Champagne Cossette, Mohammed Ayman Shalaby, David Saussié +1
This paper addresses the problem of decentralized, collaborative state estimation in robotic teams. In particular, this paper considers problems where individual robots estimate si…
Multi-Robot Relative Pose Estimation and IMU Preintegration Using Passive UWB Transceivers
Mohammed Ayman Shalaby, Charles Champagne Cossette, Jerome Le Ny +1
Ultra-wideband (UWB) systems are becoming increasingly popular as a means of inter-robot ranging and communication. A major constraint associated with UWB is that only one pair of…
