The invention relates to an information-fusion-mechanism-based multi-
robot dangerous
odor source positioning method. In the conventional methods, information is incompletely utilized, and communication constraints are not taken into account, so a multi-
robot system may be locally convergent. The method provided by the invention comprises the following steps of: first establishing an
information fusion matrix and an
odor source position mean value distribution
probability model, extracting mean value information, and storing the extracted mean value information into the
information fusion matrix; then establishing
odor source position probability distribution according to the mean value information, and extracting position information; and finally controlling robots to move to a target position by adopting spiral paths as motion trails of the robots based on probable positions and current position of an
odor source, and continuously updating position information, corresponding to maximum concentration, obtained by the
robot group and the position information, corresponding to the maximum concentration, obtained by individual robots until a given position is obtained. By the method,the multi-robot
system can rapidly position the dangerous
odor source, and effectively provide the probable positions of the dangerous
odor source under the conditions of communication constraints.
