Moving obstacle path detection for mobile robot

چکیده
This paper presents a system that detects a path of moving obstacle that appear in the path of a navigating robot. The objective of the system is to avoid collision between mobile robot and moving obstacles. The system uses polar mapping to simplify the segmentation of the moving object from the background. In the transformed space qualitative extimation of moving obstacles is obtained by detecting the vertical motion of edges extracted in a few specified directions. The moving obstacle area is computed by component labeling and matching components of the same class over the two images. From moving area we present the method to compute the moving-angle which show the path of moving obstacles related to the path of the robot. Last we present the collision-angle which show the collision path of the moving obstacle. Resulted of experiment with a mobile robot under realistic conditions are given and discuss.

متن کاملA New Method of Mobile Robot Navigation: Shortest Null Space
In this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. The robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (SNS) toward the goal. In the case of no obstacle, SNS was a direct path from the robot to goal; however, in the presence of obstacles, SNS was a space around the r...
