With the arrival of new robotic technologies such as an Autonomous Underwater Vehicle (AUV), a number of tasks that cannot be done by human now can be accomplished and bring human to reach the dangerous and unreachable areas. An AUV can be related to the most invention which can reduce human's work using specialized equipment and devices that control and perform the particular tasks. Therefore, it is able to fulfil the predetermined task without any human control and to react against unexpected situation by its artificial intelligence. This paper examines the effectiveness of using AUV as surveillance system for coral reef ecology. We propose a new AUV that ease researcher or activist to survey the condition of coral reef ecology environment.
