Researchers from MIT and EPFL have created a flapping robot capable of transitioning between water and air without legs. Weighing approximately 250 grams, the robot features a streamlined body, two flexible wings, and a controllable tail. It can flap its wings at frequencies of up to 6 Hz underwater and 5.2 to 11 Hz in the air, mimicking the behavior of diving birds, as detailed in a recent Science publication.
This innovation is significant as it addresses the complex physical challenges of transitioning from water to air, a feat that most diving birds achieve with the aid of their legs. The robot's flexible wings reduce drag and allow for a higher flapping frequency underwater compared to rigid wings. This design not only enhances its swimming efficiency but also aligns with biological observations of diving birds, providing insights into their locomotion strategies.
Looking ahead, the research team is exploring optimal wing configurations and has tested various sizes and stiffnesses. Future experiments will focus on the robot's ability to transition from water to air solely through wing flapping, a critical milestone that could reveal more about the mechanics of avian flight and inspire advancements in robotic design. No further timeline was disclosed at the time of publication.
