Abstract
In this study, a compact and modular underwater robot is proposed. By designing the robot in modules, the functionality of the system can be changed easily depending on the purpose of objective of the user. These modules are battery operated isolated smart systems that use wireless communications. In some missions, the noise made by the robot should be reduced so as not to disturb living organisms that are to be observed. This paper describes the development of the low-noise type thruster module of the robot. A prototype and basic performance tests are presented.
