四旋翼飞行机器人的浮体式降落平台设计

Design and Research of Landing Platform for Quadrotors

针对四旋翼飞行机器人降落平台主要通过弹簧实现减震的局限,研究设计了浮体式降落平台。介绍了这种浮体式降落平台的基本结构和工作原理。在全面考虑飞行器降落情况的基础上,设计的降落平台主要借助水的浮力、器件的摩擦力和橡皮条、弹簧的弹力的综合作用来削减飞行器降落时导致的反冲力。实验结果表明,浮体式降落平台可以有效减少四旋翼飞行机器人在降落时受到的震动,有利于保护飞行器及其装载设备的安全。

This paper takes the landing platform for quadrotors as the investigation object. When quadrotors land on a floating plafform from vertical direction or sideways, the floating body will move downward, at the same time with a lateral movement; then the universal wheel will rise along the inner wall of the tray, to slow down under the action of gravity. And when the position is fixed, the rubber strip is straightened to assist the floating body to pull back to the middle part, so the recoil is not too large. After the speed slows down, the friction has a negative effect to prevent it from rising too fast （under the loire of buoyancy and the role of rubber bands） , making the landing platform gentler, so the damping effect is better.
