Autonomous mobile robots are being extensively used in the area of navigation in different environment. It is essential for autonomous mobile robots to plan shortest return path to goal quickly in real world without any human intervention. This paper intends the approach to improve the information for better return path planning. The positioning is the most significant part of the path planning. Accurate positioning and path planning requires the virtuous tracing of the path travelled by robot. The paper proposes the effective method of tracing the robot path travelled to record the significant information. Copyright © 2016 Inderscience Enterprises Ltd.
