Abstract: Throughout the 20 weeks in Winter and Spring quarter, we were able to plan, design, and simulate our Capstone project. Our chosen problem was to address the over-pollution of plastic in the ocean. Therefore our proposed solution was an autonomous trash-collecting boat. With this solution in mind, we went through the rigorous engineering process of planning, designing, and validating our design in order to meet chosen design criteria. This included the rate of trash collection, the trash carrying capacity, the price per trash collected, and the duration of the trip. Once this design criteria was chosen, software tools such as Webots and Solidworks were used to both inform our design and validate design choices. Further validation work such as FEA, CFD, and fatigue analysis were also done our results were simulations with both an analytical python simulation and physical Webots simulation. From all these tools we were able to successfully design an autonomous fiberglass catamaran that is powered via diesel-electric motors. Our trash collection system has a custom conveyor belt outfitted with a stainless steel mesh funnel for optimal trash collecting efficiency. From all these design choices, we were able to determine that our boat is able to remove 1.03% of trash from the GPGP during it’s lifetime which consists of 823,000 kg of trash.
