Aerial Localization and Navigation for Surveillance of Large, Featureless, GNSS‐Denied Maritime Environments

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT In this study, we tackle the problem of surveilling a large area over the sea without access to the global navigation satellite system (GNSS) while searching for the known target vessel. The system utilizes an unmanned aerial vehicle (UAV) equipped with long‐range radio frequency (LoRa) localization and an RGB camera to detect the target ...

Phylogenomics of African Melastomateae (Melastomataceae): Revisiting generic relationships, placement of three enigmatic taxa and description of two new genera

open access: yesTAXON, EarlyView.
Abstract Evolutionary relationships within the Melastomateae, a diverse tribe within the Melastomataceae, are not yet completely resolved, and some putatively paleoendemic taxa that might alter relationships are still unsampled. This study employs a phylogenomic approach, utilizing target capture data, to revisit generic relationships and shed light on

Design of a Marker‐Based Human–Robot Following Motion Control Strategy

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT To address the challenges of jerky movements and poor tracking performance in outdoor environments for a following‐type mobile robot, a novel marker‐based human–machine following‐motion control strategy is explored. This strategy decouples the control of linear velocity and angular velocity, handling them separately.
