Multi-Robot Bearing-only Pose Estimation via Angle Rigidity
J. Francisco Presenza, Leonardo J. Colombo, Ignacio Mas +1
This letter proposes a novel distributed bearing-based pose estimator for time-varying multi-robot systems. The method uses angles computed from body-frame bearings to estimate the…
Angle-based Localization and Rigidity Maintenance Control for Multi-Robot Networks
J. Francisco Presenza, Leonardo J. Colombo, Juan I. Giribet +1
In this work, we study angle-based localization and rigidity maintenance control for multi-robot networks. First, we establish the relationship between angle rigidity and bearing r…
Adaptive Multirobot Virtual Structure Control using Dual Quaternions
Juan I. Giribet, Alejandro S. Ghersin, Ignacio Mas +3
This paper presents a control strategy based on dual quaternions for the coordinated formation flying of small UAV groups. A virtual structure is employed to define the desired for…
Subframework-based Bearing Rigidity Maintenance Control in Multirobot Networks
J. Francisco Presenza, Ignacio Mas, J. Ignacio Alvarez-Hamelin +1
This work presents a novel approach for \textit{bearing rigidity} analysis and control in multi-robot networks with sensing constraints and dynamic topology. By decomposing the sys…
Efficient Endangered Deer Species Monitoring with UAV Aerial Imagery and Deep Learning
AgustÃn Roca, Gabriel Torre, Juan I. Giribet +4
This paper examines the use of Unmanned Aerial Vehicles (UAVs) and deep learning for detecting endangered deer species in their natural habitats. As traditional identification proc…
Detection of Endangered Deer Species Using UAV Imagery: A Comparative Study Between Efficient Deep Learning Approaches
AgustÃn Roca, Gastón Castro, Gabriel Torre +4
This study compares the performance of state-of-the-art neural networks including variants of the YOLOv11 and RT-DETR models for detecting marsh deer in UAV imagery, in scenarios w…
