The attempts of robot implementations and simulation framework designs for the solution to three dimensional robot active olfaction problems are reviewed. A numerical model is proposed to dynamically simulate the gas dispersion under the air flow disturbance introduced by the rotating propellers of gas-sensitive unmanned aerial vehicles (UAVs). The model is an interdisciplinary approach that integrates...
A novel mobile robot based gas source localization method in which the top-down visual attention mechanism (TDVAM) is combined with shape analysis is proposed. At each location, three different images which cover the scene in front of the robot are captured via changing the horizontal angle of an onboard pan/tilt camera. In each image, three salient regions are computed using TDVAM model, and maximal...
