This research proposed an intelligent obstacle avoidance algorithm to navigate an autonomous mobile robot. The presented Intelligent Bug Algorithm (IBA) over performs and reaches the goal in relatively less time as compared to existing Bug algorithms. The improved algorithm offers a goal oriented strategy by following smooth and short trajectory. This has been achieved by continuously consideri...

It is difficult to detect all dynamic obstacles around a robot due to the limitation of field of view. Visibility information is necessary in order to avoid collisions. In previous research, we proposed a path planning and speed control scheme that could be applied to a robot to avoid occluded dynamic obstacles. In this paper experimental verifications of the proposed scheme for various environ...

Despite the existence of obstacles in many database applications, traditional spatial query processing utilizes the Euclidean distance metric assuming that points in space are directly reachable. In this paper, we study spatial queries in the presence of obstacles, where the obstructed distance between two points is defined as the length of the shortest path that connects them without crossing ...

Some theoretical and experimental studies have been developed to obtain independent equipment for inspection and maintenace of electric and communication lines, allowing to increase the efficiency of the process and to reduce the risk of accidents with the employees who execute the task. This activity is perfectly adequate for mobile robots because they are capable to move in avoiding the exist...
