[O11-P37] Development of a solar-powered boat controlled by an autonomous navigation system
Keywords:a solar-powered boat, an autonomous navigation system, Lake Biwa
In order to address environmental problems in Lake Biwa, I'm developing a robot controlled by an autonomous navigation system used for water quality monitoring. Using Python, I created a program to navigate specified coordinates based on GPS and compass data. Initial land tests revealed issues with processing delays in GPS data, which were resolved by removing wait times. To test the program and gain practical knowledge, I participated in the “E/SASV Games,” a 20-km race across three set points on Lake Biwa using a solar-powered boat.To participate in this race, I made a solar-powered boat equipped with a Raspberry Pi Zero W, compass, GPS, and motor. While the boat secured third place, challenges such as overheating, imprecise servo control caused by the limitations of the Raspberry Pi, and inadequate speed against waves were identified. Improvements for future development include better heat management, switching to a microcontroller for precise servo control, and enhancing speed and stability in rough conditions.
