Preliminary physical prototype design of autonomous surface vehicle (asv)

Abstract

An Autonomous Surface Vehicle (ASV) is a mobile robot designed for aquatic work environments that travel on the water surface and can function without cable or remote control. ASV nowadays is an automatic self-propelled which equipped with rechargeable battery and photovoltaic cell to provide long-lasting power to the system. With solar charge controller, the excess power was stored into the battery which is the system can get the continuously power from the battery. Used renewable energy allows ASV to stay on the surface for long-term by using solar power to recharge the battery. This research about the development of ASV that used double thrusters and wide water plane are used to build the prototype that can handle 6 character of sea. Besides that, the prototype supported by an Arduino UNO board and L298N motor shield to control the movement and power to the others component. Besides that, this ASV also equipped with ultrasonic sensor to avoid the object in fronts them. This prototype can be used in Malaysian Coastal only because due to hot weather and damp throughout the year which can provide sufficient solar ray to the prototype. By using renewable energy which is from solar, new source of alternative power for marine research was developed.
