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.
