Evan Budz, a 15-year-old prodigy, has revolutionized the field of underwater robotics with his creation, BURT (Bionic Underwater Robotic Turtle). This remarkable device, modeled after the graceful swimming mechanics of a green sea turtle, is an autonomous robot designed to detect ecological threats in aquatic environments with astonishing accuracy. With a focus on minimizing environmental impact, Budz's innovation has already garnered significant recognition, including first prize at the European Union Contest for Young Scientists (EUCYS) and the Ellison Scholars Award, which includes a trip to Oxford University.
What makes BURT truly remarkable is its ability to navigate and detect threats without causing harm to delicate ecosystems. Traditional underwater drones often use propellers or high-pressure water jets, which can damage habitats and stress marine life. Budz, however, sought a quieter approach. He meticulously studied sea turtle locomotion, observing how they use their front flippers for propulsion and rear limbs for steering. This inspired him to design BURT with four flippers, each serving a specific function, mimicking the natural movement of its animal counterpart.
The robot's body is an acrylic tube housing a Raspberry Pi microcomputer, which runs AI detection models and manages data recording and transmission. External sensors, including a front-mounted camera, depth control, GPS-guided navigation, and obstacle detection, further enhance its capabilities. BURT's design also incorporates a lithium battery and a solar panel to extend its operational range, ensuring it can swim at a pace similar to that of a real sea turtle (approximately 0.5 miles per hour).
Budz's development process began in his grandparents' backyard pool, where he created a simulated coral reef using 3D models. He programmed BURT to recognize coral bleaching and invasive species, allowing him to test its detection capabilities in a controlled environment. The robot follows a predetermined search grid, eliminating the need for a tether or remote operator, and all data is recorded and transmitted for further analysis.
One of the most impressive aspects of BURT is its adaptability. Budz has expanded its capabilities to address murkier water conditions by adding lights and an ultrasonic transducer for obstacle detection. He has also developed a holographic imaging device that can classify microplastics, further showcasing the robot's versatility and potential for addressing various environmental concerns.
Budz's passion for environmental conservation is evident in his philosophy, as quoted in an interview with Popular Science. He believes in leaving places better than he found them, and this mindset has driven his innovative approach to underwater robotics. With his award-winning project, Budz has not only demonstrated exceptional technical prowess but has also highlighted the importance of sustainable and gentle environmental monitoring.
The future looks bright for BURT and its creator. Budz aims to deploy a fleet of these robots to monitor aquatic environments, targeting coral bleaching, invasive species, and microplastics. His dedication to environmental conservation and technological innovation has the potential to make a significant impact on our understanding and protection of underwater ecosystems. As BURT continues to evolve, it will undoubtedly play a crucial role in preserving the delicate balance of our oceans.
