Towards Agile Vision-Based Multi-UAV Flight: Revisiting State Estimation
Michal Pliska, Matouš Vrba, Ondřej Víta +3
Agile multi-UAV flight requires accurate and low-latency onboard estimation of the kinematic states of neighboring UAVs for collision avoidance, motion coordination, etc. Most visi…
Reflection-Based Relative Localization for Cooperative UAV Teams Using Active Markers
Tim Lakemann, Daniel Bonilla Licea, Viktor Walter +1
Reflections of active markers in the environment are a common source of ambiguity in onboard visual relative localization. This work presents a novel approach that exploits these t…
FIMD: Fast Isolated Marker Detection for UV-Based Visual Relative Localisation in Agile UAV Swarms
Vojtěch Vrba, Viktor Walter, Petr Štěpán +1
A novel approach for the fast onboard detection of isolated markers for visual relative localisation of multiple teammates in agile UAV swarms is introduced in this paper. As the d…
Distributed Lloyd-Based algorithm for uncertainty-aware multi-robot under-canopy flocking
Manuel Boldrer, Vit Kratky, Viktor Walter +1
In this letter, we present a distributed algorithm for flocking in complex environments that operates at constant altitude, without explicit communication, no a priori information…
Towards agile multi-robot systems in the real world: Fast onboard tracking of active blinking markers for relative localization
Tim Felix Lakemann, Daniel Bonilla Licea, Viktor Walter +2
A novel onboard tracking approach enabling vision-based relative localization and communication using Active blinking Marker Tracking (AMT) is introduced in this article. Active bl…
Fast Collective Evasion in Self-Localized Swarms of Unmanned Aerial Vehicles
Filip Novák, Viktor Walter, Pavel Petráček +2
A novel approach for achieving fast evasion in self-localized swarms of Unmanned Aerial Vehicles (UAVs) threatened by an intruding moving object is presented in this paper. Motivat…
MRS Drone: A Modular Platform for Real-World Deployment of Aerial Multi-Robot Systems
Daniel Hert, Tomas Baca, Pavel Petracek +18
This paper presents a modular autonomous Unmanned Aerial Vehicle (UAV) platform called the Multi-robot Systems (MRS) Drone that can be used in a large range of indoor and outdoor a…
Distributed UAV Formation Control Robust to Relative Pose Measurement Noise
Viktor Walter, Matouš Vrba, Daniel Bonilla Licea +2
A technique that allows a Formation-Enforcing Control (FEC) derived from graph rigidity theory to interface with a realistic relative localization system onboard lightweight Unmann…
Bio-Inspired Compact Swarms of Unmanned Aerial Vehicles without Communication and External Localization
Pavel Petracek, Viktor Walter, Tomas Baca +1
This article presents a unique framework for deploying decentralized and infrastructure-independent swarms of homogeneous aerial vehicles in the real world without explicit communi…
On Onboard LiDAR-based Flying Object Detection
Matouš Vrba, Viktor Walter, Václav Pritzl +5
A new robust and accurate approach for the detection and localization of flying objects with the purpose of highly dynamic aerial interception and agile multi-robot interaction is…
MRS Modular UAV Hardware Platforms for Supporting Research in Real-World Outdoor and Indoor Environments
Daniel Hert, Tomas Baca, Pavel Petracek +16
This paper presents a family of autonomous Unmanned Aerial Vehicles (UAVs) platforms designed for a diverse range of indoor and outdoor applications. The proposed UAV design is hig…
Design and Deployment of an Autonomous Unmanned Ground Vehicle for Urban Firefighting Scenarios
Kshitij Jindal, Anthony Wang, Dinesh Thakur +7
Autonomous mobile robots have the potential to solve missions that are either too complex or dangerous to be accomplished by humans. In this paper, we address the design and autono…
