In the field of autonomous vehicle research, maintaining accurate estimates of a vehicle's velocities, position, and orientation is crucial to successful navigation. Normally, this information can be obtained through the use of a GPS system. However, GPS signals are not always available in some of the more exotic or dangerous locations that a vehicle might be dispatched to. This paper proposes a hybrid...
In order to have an operative system with multiple robots each one with its own configuration, it is important to establish cooperative mechanisms that allow the robots with less sensory power to get helped from the robots with more sensory power. In this context, it is important that the cooperation is done in a way that allows each robot to take advantage of the particular resources of the other...
This work addresses the use of optical flow to supervise the navigation of mobile robot. The optical flow information is computed from the images sequence in order to be used in the navigation algorithm. The optical flow provides very important information about the robot environment, like: the obstacles disposition, the robot heading, the time to collision and the depth. The use of this information...
