Abstract:
In this paper a fuzzy path planning method is proposed to navigate a robot in complex environments. The static form of the environment is assumed to be known, butthere is no prior knowledge about the dynamic obstacles. In this situation an online and realtime approach is essential foravoiding collision. In the proposed algorithm, the global path between the start and goal points of the environment is divided to local small paths. The start point of each local path is supposed to be a local start point and the end point of each local path is supposed to be a local goal point. To reach theglobal goal point, nanorobot should avoid colliding with any obstacles. A fuzzy logic algorithm with two strategies is designed in order to seek the local targets and to avoid obstacles. To demonstrate the efficiency of the proposed approach Monte Carlo simulation with random numbers isused, where the dynamic obstacles are assumed to appear in exponential distributed random time intervals
