Many onboard navigation systems use the Global Positioning System to bound the errors that result from integrating inertial sensors over time. Global Positioning System information, however, is not always accessible since it relies on external satellite signals. To this end, a vision sensor is explored as an alternative for inertial navigation in the(More)
This paper describes the design, development, and testing of Unmanned Aerial Vehicles (UAV) with highly automated search capabilities. Here, systems are able to respond on their own in the presence of considerable uncertainty utilizing an image processor, tracker/mapper, mission manager, and trajectory generation; and are used to complete a realistic(More)
Landing an aircraft in a remote landing zone autonomously presents several challenges. Firstly, the exact location, orientation, and elevation of the landing zone is not always known; secondly, the accuracy of the aircrafts navigation solution is not always sufficient for this type of precision maneuver. This paper explores a method for estimating the(More)
The Ocean Technology Test Bed (OTTB) is a multi-functional underwater test facility developed by the Ocean Technology Lab (OTL) at the University of Victoria to serve military, academia, government and industry. The OTTB is located off the coast of Vancouver Island, Canada. It resides in 80m of water and covers 2-square kilometers of the seafloor. A(More)

In the mobile robot navigation, the ultrasonic sensors have been widely used for the obstacles detection and map building because of its cost and efficiency. Generally sensors are used to increase the accuracy of the obstacles position and decrease the time. In this paper an ultrasonic sensor is interfaced on to a stepper motor which will be constantly(More)
