ABSTRACT
In recent years, the oceans debris is increased because of human’s activity.
Especially, the plastic debris, such as plastic bottles, is not biodegradable,
and therefore those are creating serious environmental problems. The ocean
debris collecting in the world is done through volunteer activities. However,
these activities require a lot of time and labor. In this research, we
proposed a method of ocean debris collecting USV operation method. Also,
we designed and developed a USV (Unmanned Surface Vehicle) for the purpose
of autonomous oceans debris collecting mission and evaluated the developed
ocean debris collecting device. In the development of USV, electronic parts,
which are to operate the mission autonomously, were selected. Then, each
electronic part was placed inside the waterproof box according to the designed
power and communication system diagram. In the development of oceans debris
collecting device, we designed a belt conveyor type device. A motor was
selected to rotate the device and a decelerator, which used the planetary
gear mechanism, was designed. To evaluate the performance of the developed
ocean debris collecting device, we tested various types of plastic bottles
in tank environment. As a result of the experiment, the developed USV collected
various types of plastic bottles with a 47.7% probability.
