FLYING ROBOTS: Sensing, Control and Decision Making

This paper presents a flight management system (FMS) implemented as on-board intelligence for rotorcraftbased unmanned aerial vehicles (RUAVs). This hierarchical flight management system endows each vehicle with autonomy resembling sense-reason-act processes of intelligent agents in nature. Sensor measurements are processed by flight control computers in order to gradually refine given abstract...

Flying Robots: Modeling, Control and Decision Making

This paper presents a flight rnanageiiient system (FhIS) iinpleniented as on-board intelligence for rotorcraft-based unmanned aerial vehicles (RUAVs), in order to gradually refine gilen abstract mission coniinands into real-time control signals for each vehicle. A strategy planner uses the probabilistic decision making algorithms to determine suboptinial action at each time step. A graphical in...

Mechanisms of Cache Decision Making in Fox Squirrels (sciurus Niger)

The cache decisions of scatter-hoarding animals are influenced by a number of factors, including satiety, food quality, number of competitors, and the risk of predation and pilferage. However, it is unknown how animals assess these variables. We investigated this process experimentally in free-ranging fox squirrels (Sciurus niger) by measuring the effects of nut characteristics and social conte...

Ultrasonic Vocalizations Emitted by Flying Squirrels

Anecdotal reports of ultrasound use by flying squirrels have existed for decades, yet there has been little detailed analysis of their vocalizations. Here we demonstrate that two species of flying squirrel emit ultrasonic vocalizations. We recorded vocalizations from northern (Glaucomys sabrinus) and southern (G. volans) flying squirrels calling in both the laboratory and at a field site in cen...
