【Abstract】 To cope with the positioning problem of mobile robots in outdoor environments, a combined inertial navigation/GPS positioning algorithm is proposed. Through Gauss-Krüger coordinate projection, the robots’ geographic location coordinates are converted to rectangular coordinate system coordinates, EKF filter is used to fuse sensor information for combined positioning, and based on the STM32 development platform, the mobile robot hardware platform is built for experiments, with which simulation comparison is performed by MATLAB with the results showing that the proposed combined positioning algorithm has high positioning accuracy.更多还原
