"What's better than a robot inspired by bees? A robot inspired by bees that can swim," said Katherine Ellen Foley at Quartz. Researchers guided by a team of scientists from Harvard University have developed a tiny, bee-size bot, weighing the same as "about two feathers," to study the ocean. The robot has "insect-inspired wings that can both flap and rotate," allowing it to dive into water, swim, take off again, and land safely.
