According to the characteristic of Radar Cross Section (RCS) of the aircraft and the Schematic graph of the radar range, Flight with certain constant azimuth can make the generic aircraft which does not have the ability of stealth eluding radars in battlefield. The form of spatial curve that the flying aircraft follows with constant azimuth is first proved, then the algorithm for getting path points...
Reliable navigation in the Wireless Sensor Networks (WSNs) always require mobile robot do localization and environment map building processes, which depends heavily on estimating the position of the features within the entire surroundings, that means as a sensor receiving platform, the robot needs to detect and process information transmitted from sensors as much as possible, in order to perform tasks...
This paper presents a practical topological navigation system for indoor mobile robots, making use of a novel artificial landmark which is called MR (Mobile Robot) code. This new kind of paper-made landmarks can be easily attached on the ceilings or on the walls. Localization algorithms for the two cases are given respectively. An approaching control algorithm and an extended line tracking algorithm...
A novel 2D code which can be used as an efficient artificial landmark system for indoor mobile robot and is thus called MR (mobile robot) code, is described in this paper. A real time detection-recognition algorithm for this MR code is also proposed. Experiments in cluttered indoor environments under various viewing angles and illumination conditions are carried out to show the effectiveness and robustness...
