A Multi-Sensory Robot Used for Searching Toxic Gas Leak Source

For filling the application requirement of searching toxic gas leak source, a multi-sensory robot, which is used for searching toxic gas leak source, is developed. This robot consists of humanoid multiple degree of freedom head system and tracked walking mechanism, with the sense of smell, hearing and stereo vision and other functions. The robot’s bionic olfaction system can detect 5 kinds of toxic gas in the same time, and the hearing system consisted of four microphones can get all kinds of sound in the general environment. Meanwhile, its binocular stereo vision system can get the 3D information of the work environmental. Distributed controll system is constructed for the robot, and comprehensive utilization of the multi-sensory function can increase the efficiency and accuracy of searching leakage. This robot can give full play the advantage of multiple degrees of freedom to expand the searching scope of the robot, and enhance the flexibility of the searching behavior. This robot system has wide application prospects in the environment of toxic gas.
