– In this paper, adaptive tracking control of an underactuated quadrotor is addressed. Position and yaw trajectory tracking is designed using state feedback control system and an integrator backstepping approach is applied to this coupled and cascaded dynamic system. The control design is further complicated by considering the parametric uncertainty of the… (More)
The paper reports an exploratory project to provide research experiences on swarm robotics to high school students. A group of three simple mobile robots (Lego NXT) was used to study 'search and rescue' operation. A bio-inspired global optimization technique called particle swarm optimization (PSO) was used as the main algorithm. Each robot was placed in… (More)
Vehicular ad hoc networks, based on vehicle-to-vehicle, vehicle-to-infrastructure communications, promise valuable applications to enhance driving safety, comfort, and efficiency. In this paper we propose the problems and solutions when using GPAS, general purpose automatic survey system based on VANETs. The key motivation of GPAS is to explore the… (More)
