Abstract

This report is about Design of sensory system for obstacle avoidance for underwater application using a laser distance finder. Unmanned Underwater Vehicle (UUV) equipped with a variety of sensors and components depending upon the mission of the application of UUV or application of the vehicle. One of the biggest challenges in developing the UUV with complicated systems is the cost. UUV must be able to interpret its environment by gathering information from its sensors with higher accuracy. This is due to unpredicted condition in a deep sea where serious collision might occur if this kind of sensory system is not implemented to the UUV. The purpose of this Final year Project is to develop a sensory system that able obstacles avoidance for underwater application using laser distance finder as a tool to measure and detect obstacles at a required range. Next, to investigate the performance of laser distance finders in terms of range (distance between obstacles), accuracy and material detected. Lastly the objective is also to analyze the performance of underwater sensors on obstacle detection and distance measurement in underwater. The components used which is inexpensive Arduino Nano as microcontrollers, 5 mm blue LED and sensor using laser distance finder result in an autonomous vehicle that will able to avoid any obstacles while moving to a location. The laser distance finder is characterized by a wide-angle spatial transmission pattern, high range resolution, short minimum detection range and fast response time. The result will be that laser distance finder will be able to detect obstacles and also cause the UUV to avoid the obstacles in depth control.
