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 interactions from lasting long enough to achieve coherent swarming. To alleviate this dependency, most(More)
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 consequence, they tend to be complex, require a significant amount of processing power and are usually(More)
In the last decades, the development of flying robots has made much progress. However, a flying platform for outdoor robot experiments, in particular research in collective systems, which fulfills the main criteria of safeness, ease of use, robustness and simplicity does not exist yet. Rather, current systems (e.g. the ones used in [1], [2] and [3]) tend to(More)
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 only communication hardware (e.g. WiFi module or radio modem) instead of GPS or cameras. To avoid being(More)
Thermal soaring saves much energy, but flying large distances in this form represents a great challenge for birds, people and unmanned aerial vehicles (UAVs). The solution is to make use of the so-called thermals, which are localized, warmer regions in the atmosphere moving upward with a speed exceeding the descent rate of birds and planes. Saving energy by(More)
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 require continuous forward motion to fly. For such platforms, performing trajectories with forward speed(More)
In case of a wide-area catastrophic event, rescuers often need a dedicated communication system allowing them to exchange information with a base station and with other rescuers. In this project, we are developing a swarm of small and lightweight flying robots that will autonomously locate the rescuers and establish a communication network with the base(More)
