Improving the efficiency of detecting the spatial distribution of gas information with a mobile robot is a great challenge that requires rapid sample collection, which is basically determined by the speed of operation of gas sensors. The present work developed a robot equipped with a high-speed gas sensor module based on localized surface plasmon resonance. The sensor module is designed to sample gases from an on-ground odor source, such as a footprint material or artificial odor marker, via a fine sampling tubing. The tip of the sampling tubing was placed close to the ground to reduce the sampling time and the effect of natural gas diffusion. On-ground ethanol odor sources were detected by the robot at high resolution (i.e., 2.5 cm when the robot moved at 10 cm/s), and the reading of gas information was demonstrated experimentally. This work may help in the development of environmental sensing robots, such as the development of odor source mapping and multirobot systems with pheromone tracing.

配备有高速LSPR气体传感器模块的机器人,用于从地面上看不见的气味源中收集空间气味信息

用移动机器人提高检测气体信息的空间分布的效率是一项巨大的挑战,需要快速采集样本,而这基本上取决于气体传感器的运行速度。本工作开发了一种机器人,该机器人配备了基于局部表面等离振子共振的高速气体传感器模块。传感器模块设计用于通过细采样管从地面气味源(例如脚印材料或人造气味标记)采样气体。采样管的尖端靠近地面放置,以减少采样时间和天然气扩散的影响。机器人以高分辨率(即,当机器人以10 cm / s的速度移动时为2.5厘米)检测到地面上的乙醇异味源,并通过实验证明了气体信息的读取。
