Here we present the design of an insect-scale electromagnetic actuator that can be used to spin wings and generate lift. This lift generation method is in contrast to most other microrobot designs at this size scale which rely on flapping wings to produce lift. The device has a wing span of 4 centimeters and weighs 133 milligrams. It spins its wings at 47 revolutions/second generating > 138 milligrams of lift while consuming approximately 60 milliwatts of total power and operating at a low voltage ( < 3 V). Of the total power consumed 8.8 milliwatts is mechanical power generated, part of which goes towards spinning the wings, and 51 milliwatts is wasted in resistive Joule heating. With a lift-to-power ratio of 2.3 grams/W, its performance is at par with the best reported flapping wing devices at the insect-scale.

昆虫级旋翼机器人电磁致动器的设计


在这里，我们提出了一种昆虫级电磁致动器的设计，可用于旋转翅膀并产生升力。这种升力产生方法与大多数其他这种尺寸的微型机器人设计形成鲜明对比，后者依靠扑动翅膀来产生升力。该装置翼展4厘米，重133毫克。它以 47 转/秒的速度旋转机翼，产生 > 138 毫克的升力，同时消耗约 60 毫瓦的总功率并在低电压 (< 3 V) 下运行。在消耗的总功率中，8.8 毫瓦是产生的机械功率，其中一部分用于旋转机翼，51 毫瓦被浪费在电阻焦耳加热中。其升力功率比为 2.3 克/瓦，其性能与昆虫规模的最佳扑翼装置相当。
