在简单机械配置的悬停能力方面，具有扑翼的飞行机器人优于传统的固定或旋转翼。直到最近，用于这种机器人的可用致动器仅限于（1）具有四连杆机构的常规马达或（2）压电致动器，但由于低扑动频率、小冲程角度和/或频繁的机械故障，它们中没有一个能够提供足够的升力。研制了一种能够高频产生大行程角的新型驱动器。它由一个外置无刷电机和一个连接在扭簧上的改进电机驱动器组成。机翼直接安装在电机的盖上。建立了一个原型，并进行了初步的推力测量。将讨论适用于大功率和鲁棒作动器的机翼材料的特性。在本研究中采用的致动器利用共振振荡，这导致高能量效率。为了产生更高的升力，需要进一步研究机翼形状和方向刚度。
Flying robots with flapping wings are preferred over conventionally fixed or rotational wings in terms of hovering capability for a simple mechanical configuration. Until recently, available actuators for such a robot are limited to (1) a conventional motor with four-bar linkage mechanism or (2) a piezo electric actuator, but none of them could provide enough lift because of low flapping frequency, small stroke angles, and/or frequent mechanical failure. A new actuator capable of generating large stroke angles with high frequency is developed. It consists of an out-runner brushless motor with a modified motor driver attached to a torsion spring. The wing is attached directly on the cap of the motor. A prototype is built and preliminary thrust force measurements are performed. Properties of wing materials suitable for powerful and robust actuators will be discussed. The actuator employed in the present study utilizes resonance oscillation, which leads to high energy efficiency. Further study of wing shape and directional stiffness is needed for generating higher lift capability.
