The use of aerial swarms to solve real-world problems has been increasing steadily, accompanied by falling prices and improving performance communication, sensing, processing hardware. commoditization hardware reduced unit costs, thereby lowering the barriers entry field swarm robotics. A key enabling technology for is family algorithms that allow individual members communicate allocate tasks amongst themselves, plan their trajectories, coordinate flight in such a way overall objectives are...

Selecting actions that decrease uncertainty while not significantly increasing robot's localization is challenging. We present novel information-theoretic utility function both...
This paper considers situations in which a team of mobile sensor platforms autonomously explores an environment to detect and localize unknown number targets.

Firstly, it decentralized. follows from approximation fact robots' environmental have finite area influence. Secondly, allows be...
Magnetic anomaly detection (MAD) is an important problem in applications ranging from geological surveillance to military reconnaissance. MAD sensors detect local disturbances the magnetic field, which can be used existence of and estimate position buried, hidden, or submerged objects, such as ore deposits mines. These may experience false positive negative detections and, without prior knowledge targets, only determine proximity a target. The uncertainty sensors, coupled with lack even...
Accurately tracking dynamic targets relies on robots accounting for uncertainties in their own states to share information and maintain safety. The problem becomes even more challenging when there is an unknown time-varying number of the environment. In this paper we address by introducing four new distributed algorithms that allow large teams to: i) run prediction ii) update steps a recursive Bayesian multi- target tracker, iii) determine set local neighbors must exchange data, iv) data...
