Enquadramento

Research interest in small-scale Unmanned Aerial Vehicles (UAVs), particularly quadrotors, is growing rapidly due to their wide range of applications and their potential to perform tasks that are costly to be performed by humans or threat humans’ safety. Quadrotors have four rotors that make them very agile in attaining the full range of motion (capability of hovering, horizontal flight, and vertical take-off and landing). Despite their flying ability, quadcopters are too small for many tasks and have a very low battery life (due to the extra motors they carry). For this reason, in many applications a group of collaborative autonomous quadcopters will be needed to accomplish a mission. In these applications, safety is one of the top concerns. Ensuring safety of a system including a swarm of autonomous quadrotors is everything but simple, because it consists of several potentially dangerous (e.g., high-speed motors and propellers), and faulty components (software and hardware).

Objetivo

The goal of this work is to identify, characterize, and analyze possible failure scenarios in the system with a swarm of autonomous quadrotors. To this end, we will need to 1) build a model of the system including all necessary components; 2) identify the possible faults and crash modes of each component involved in the model (e.g., loss of Wi-Fi); 3) identify the causes of the crashes that may occur in each component (e.g., loss of signal due to interference); 4) identify the failures that may occur due to the faults and crashes (e.g., loss of control in quadrotors); 5) identify the possible solutions for tolerating the crashes and faults (e.g., use a secondary communication channel); 6) identify the faults to be injected or the ways the crashes should be emulated for testing purposes (e.g., use tcpkill to emulate connection crashes). In practice, the expected outcomes of this includes writing a research paper to be submitted to a related international conference.
