Design of a Modular Bionic Olfaction System for Robot

The robot with olfaction has extensive applications, such as detecting toxic gases, searching explosives, detecting leakage, etc. Following the robot modular design concept, the paper designs a modular bionicol faction system for robot, which is comparable to human being´s nasal cavity structure, can simultaneously detect five kinds of different toxic gases, namely, CO, SO₂, H₂S, Cl₂ and NH₃, and can conveniently change corresponding gas sensors based on the target gases. By virtue of the compact structure, simple mechanical interface and communication inter face, not only can the bionicol faction system be used as portable olfaction device, but also as a robot standardized component assembling all types of robots to help the accomplishment of works related to olfaction.
