Beat-based synchronization and steering for groups of fixed-wing flying robots

Jean-Christophe Zufferey, Dario Floreano, Sabine Hauert, Severin Leven

Groups of fixed-wing robots can benefit from moving in synchrony to share sensing and communication capabilities, avoid collisions or produce visually pleasing choreographies. For this reason, we provide a strategy to produce global group movement that can ...

Beat-Based Synchronization and Steering for Groups of Fixed-Wing Flying Robots

Jean-Christophe Zufferey, Dario Floreano, Sabine Hauert, Severin Leven

Groups of fixed-wing robots can benefit from moving in synchrony to share sensing and communication capabilities, avoid collisions or produce visually pleasing choreographies. Synchronous motion is especially challenging when using fixed-wing robots that r ...

Dealing with Mid-Air Collisions in Dense Collective Aerial Systems

Jean-Christophe Zufferey, Dario Floreano, Severin Leven

The idea of creating collective aerial systems is appealing because several rather simple flying vehicles could join forces to cover a large area in little time in applications such as monitoring, mapping, search and rescue, or airborne communication relay ...

Enabling Large-Scale Collective Systems in Outdoor Aerial Robotics

Severin Leven

For many real-life applications such as monitoring, mapping, search-and-rescue or ad-hoc communication networks, fleets of flying robots are expected to out-perform existing solutions. Robots can join forces to cover larger areas in less time, act as effic ...

Reynolds flocking in reality with fixed-wing robots: communication range vs. maximum turning rate

Jean-Christophe Zufferey, Dario Floreano, Sabine Hauert, Severin Leven, Maja Varga

The success of swarm behaviors often depends on the range at which robots can communicate and the speed at which they change their behavior. Challenges arise when the communication range is too small with respect to the dynamics of the robot, preventing in ...

Communication-based Swarming for Flying Robots

Jean-Christophe Zufferey, Dario Floreano, Sabine Hauert, Severin Leven

We aim at implementing a swarm of Micro-Air-Vehicles for creating communication networks (SMAVNETs) in disaster areas. For this purpose, we propose strategies for steering flying robots using only communication hardware (e.g. WiFi module or radio modem) an ...

Communication-based Leashing of Real Flying Robots

Jean-Christophe Zufferey, Dario Floreano, Sabine Hauert, Severin Leven

Aerial robots are often required to remain within the communication range of a base station on the ground to exchange commands, sensor data or as a safety mechanism. For this purpose, we propose a minimal control strategy for steering flying robots using o ...

A Minimalist Control Strategy for Small UAVs

Jean-Christophe Zufferey, Dario Floreano, Severin Leven

Most autopilots of existing Miniature Unmanned Air Vehicles (MUAVs) rely on control architectures that typically use a large number of sensors (gyros, accelerometers, magnetometers, GPS) and a computationally demanding estimation of flight states. As a con ...

A Simple and Robust Fixed-Wing Platform for Outdoor Flying Robot Experiments

Jean-Christophe Zufferey, Dario Floreano, Severin Leven

Aerial Robotics are interesting and useful tools because they have some intrinsic advantages over ground and water based systems, like the possibility to observe things from above or to locomote without being perturbed by obstacles and rough terrain. Howev ...
