A Low Cost Raspberry PI Based Autonomous Boat

This paper presents the design and implementation of a low cost autonomous boat based on a raspberry PI as a central control unit. The autonomous boat is intended to be used in several applications such as water quality monitoring, aquaculture farms and shellfish cultivation. The hardware platform consists of a Raspberry Pi single-board computer, GPS module, compass and ultrasonic sensors, brushless motors controllers, and power management system. The Raspberry Pi is connected with Amazon Web Services (AWS) that controls motorized propellers, which provide propulsion for the system. The effectiveness of the designed autonomous boat is demonstrated through experimental trials in controlled water environments, validating the navigation accuracy, obstacle avoidance capability, and overall system robustness. The results indicate the potential for leveraging affordable technology for marine autonomy and its applicability across diverse fields.
