Summary:
We propose a dedicated local navigation system inspired by the sequence learning mechanism of the entorhinal-hippocampal loop circuit. The proposed system uses prospective and retrospective landmark sequences for dedicated human-like navigation. The retrospective landmark sequence enables the system to store and recall partially overlapped multiple routes and accomplishes the judgment of the correct direction at a crossing without any other trials. The proposed system is designed based on a standard digital manner, and the phase-coded data register unit included in the system handles both prospective and retrospective landmark sequences. In this paper, the behavior of the proposed system is described and the importance of the retrospective landmark sequences in practical local navigation is discussed using simulation results.
