Abstract

Crocodiles possess dome shaped pressure receptors called integumentary sensory organs (ISOs) on their skin, which assist crocodiles in sensing flows and locating the origin of the disturbances created by movements of other animals. The surface of each ISO is equipped with mechanoreceptors and free nerve endings, which together carry out the task of receiving mechanical stimulus. Inspired by ISOs of crocodiles, a dome with five piezoresistive pressure sensors mounted on its surface is constructed and its ability to detect an object moving in its vicinity is explored. A cylindrical rod is towed towards the dome shaped sensor and the patterns of outputs of five pressure sensors on the dome are investigated for drawing cues about the movement. The experimental results demonstrate that the dome is able to discern speed, distance and direction of the movement. The outcomes of this study serve as a building block for a prospective crocodile-inspired passive hydrodynamic sensing system which can enhance the sensing capabilities of autonomous underwater vehicles.

受鳄鱼启发的用于水下物体探测的圆顶传感器

鳄鱼的皮肤上有圆顶状的压力感受器，称为外皮感觉器官(iso)，它帮助鳄鱼感知水流，并定位其他动物运动造成的干扰的来源。每个ISO的表面都配备有机械感受器和自由的神经末梢，它们共同执行接受机械刺激的任务。受鳄鱼的iso启发，一个圆顶的表面安装了五个压阻式压力传感器，并探索了它探测附近移动物体的能力。一根圆柱形杆被拖向圆顶形传感器，并研究了圆顶上五个压力传感器的输出模式，以绘制有关运动的线索。实验结果表明，该系统能够识别物体运动的速度、距离和方向。本研究的结果为未来受鳄鱼启发的被动水动力传感系统提供了基础，该系统可以增强自主水下航行器的传感能力。
