Development of intelligent robot systems that could efficiently transport goods with the minimal time and high accuracy is an important demand for increasing the productivity of the factory. This paper reports new technologies to improve performance of the Dijkstra algorithm for the path-finding application of the transportation systems. Drawbacks of the conventional searching method are first studied for real-time situations. Two important hypotheses are then considered for the practical applications at which number of the passing nodes and the shape of the passing routine are sufficient conditions for an optimal path. Implementation of the two new features are conducted based on analyses of the conventional one and noting additional optimal objectives. The modified algorithm was successfully deployed and verified both in simulation and experiments. The testing results confirm that the proposed method could reduce the routing time of the robot system down to 14.5% as compared to the classical algorithm.
