Summary
In a significant advancement in robotics, a team at the Massachusetts Institute of Technology (MIT) has engineered a lightweight flapping robot that can both fly and swim underwater. This innovative robot, which costs approximately $300, is designed with the intention of monitoring and protecting ocean environments. The research team, led by Raphael Zufferey, an assistant professor of mechanical engineering, drew inspiration from the wing movements of diving birds such as petrels and puffins. They meticulously studied the flap frequency of these birds in both air and water, noting how variations in wingspan affected their movement.
The development of this robot, known as the Flapping Aerial-Aquatic Vehicle (FAAV), represents a notable engineering achievement, as integrating the capabilities of flying and swimming into a single vehicle poses significant technical challenges. Unlike traditional biomimicry, the FAAV features a flexible wing design that does not fold, allowing it to minimize amplitude while maintaining effective propulsion in both mediums. Zufferey emphasized that the robot operates based on programmed wingbeat frequencies, regardless of whether it is in air or water, showcasing its versatility.
