Small Scale Underwater Drone based on a Twin-Rotor System

This paper presents the development of small-scale unmanned underwater drone. The underwater drone model was selected based on a twin-rotor-like aerial platform, adapted to dive and move underwater. It designed to be performed underwater capabilities and few aerial tasks which are can slightly hover on water surface. The design of underwater drone model by using 3D drawing (Solidworks software). The propulsion mechanism of this underwater drone is based on thruster which consists of motor and propeller and for the controller part used manually by using joystick controller and the body of underwater drone using light weight material (PVC foam). The testing and experimental for underwater drone focused on vertically trajectory. In this paper also investigate propeller design by the thrust measurement so that the performances of underwater drone can be observed.
