This paper describes the development of a potential-field-based path planning method that considers an occluded region induced by light detection and ranging (LIDAR). Herein, LIDAR-induced occluded region is considered because only the surface of obstacles that causes the existence of occluded regions is detected by LIDAR. Especially at a T-junction/blind corner, the occluded region may cause inappropriate path generation when the potential-field-based path planning method is employed. To overcome the negative effect of the occluded region, we propose an occluded-region aware potential-field-based path planning method. In the proposed method, we introduce a new occluded-region repulsive potential field. The validity of the proposed occluded-region aware potential-field-based path planning method is confirmed by both simulation and an actual experiment using a mobile robot at the indoor T-junction.
