- Abstract:
-
Localization is one of the most fundamental problems in mobile robots. A method for simultaneous localization and mapping (SLAM) in robot and WSN systems using range-only measurements was presented in a Bayes framework and a particle filtering method was designed for the problem. The estimations of the robot’s path and WSN node position were set to be clusters of particles which were called status particles. The status particles were used to estimate the whole state posterior by its position and weight. The algorithm assumed position of WSN nodes which were conditioned independently along the robot’s path, so the system posterior could be computed separately. A particle filter called a robot filter was used to compute the robot’s posterior and a separate copy of each node filter corresponding to each robot particle. Due to the low dimension of range measurement, methods were made for utilizing this information. The experiment proved the efficiency and practicality of the algorithm.
