Abstract

The robot assembled electronic nose has extensive applications, such as detecting toxic gases, searching explosives, detecting leakage, etc. Following the robot modular design concept, the paper designs a bionic electronic nose for robot, which has a human-like nasal cavity structure. It can simultaneously detect five kinds of different toxic gases, namely, CO, SO2, H2S, Cl2 and NH3, by using of electrochemical gas sensor array. The electrochemical gas sensor only responds to the specific gas, and has good selectivity and linear output, so the electronic nose dispenses with the pattern recognition algorithm in measuring multi-type gases simultaneously, which greatly reduces the operation task of olfactory system and improves the detection accuracy and efficiency to meet the robotpsilas real-time requirement, and can be conveniently changed corresponding gas sensors based on the target gases. By virtue of the compact structure, simple mechanical interface and communication interface, not only can the bionic electronic nose be used as a standardized component for all types of robots to help them to accomplish works related to olfaction, but also as a portable electronic nose applied to detect toxic gas in many fields.
机器人仿生电子鼻的设计
机器人组装电子鼻具有广泛的应用,如检测有毒气体、搜索爆炸物、检测泄漏等。本文遵循机器人模块化设计理念,设计了一种具有仿人鼻腔结构的机器人仿生电子鼻。利用电化学气体传感器阵列,可同时检测CO、SO2、H2S、Cl2、NH3五种不同的有毒气体。电化学气体传感器只响应特定气体,具有良好的选择性和线性输出,因此电子鼻在同时测量多种气体时省去了模式识别算法,大大减少了嗅觉系统的操作任务,提高了检测精度和效率,满足了机器人机器人的实时性要求,并且可以根据目标气体方便地更换相应的气体传感器。仿生电子鼻结构紧凑,机械接口和通讯接口简单,不仅可以作为各类机器人的标准化部件,帮助机器人完成与嗅觉有关的工作,还可以作为便携式电子鼻,应用于许多领域的有毒气体检测。
