BOEM-SLAM: A Block Online EM Algorithm for the Visual-Inertial SLAM Backend

IROS 2022poster

In this paper we present BOEM-SLAM, a backend for visual-inertial SLAM systems capable of creating a globally consistent trajectory and map without retaining the entire history of data. By leveraging the hidden Markov model structure, BOEM-SLAM can summarize historical data into sufficient statistic…

Unsupervised Monocular Depth Learning with Integrated Intrinsics and Spatio-Temporal Constraints

IROS 2021poster

Monocular depth inference has gained tremendous attention from researchers in recent years and remains as a promising replacement for expensive time-of-flight sensors, but issues with scale acquisition and implementation overhead still plague these systems. To this end, this work presents an unsuper…

Path Planning Under MIMO Network Constraints for Throughput Enhancement in Multi-robot Data Aggregation Tasks

IROS 2020poster

Under line-of-sight (LOS) network conditions, multi-input multi-output (MIMO) wireless communications can increase the channel capacity between a team of robots and a multi-antenna array at a stationary base station. This increased capacity can result in greater data throughput, shortening the time…
