"That's relevant because when the robot's fins are at rest, the air chamber is empty, reducing the robot's buoyancy. And when the robot is flapping its fins slowly, the fins are at rest more often. In other words, the faster the robot flaps its fins, the more time the air chamber is full, making it more buoyant."
