| Abstract: | To improve the positioning accuracy of autonomous positioning robot, a dead reckoning positioning robot structure based on 3 omnidirectional driven wheels was designed. Robot's driving wheel system was composed of 4 Mecanum wheels and driven wheel system was composed of 3 omnidirectional wheels. Robot's pose information was calculated and updated according to discretized dead reckoning positioning formula. Finally, positioning error was obtained by experiments of various motion modes and different sampling periods. The experiment results show the method meets the requirements of robot indoor positioning. Theoretical basis and experimental reference of dead reckoning positioning were provided. |
