—The Global Positioning System (GPS) has been widely used in land vehicle navigation applications. However, the positioning systems based on GPS alone face great problems in the so-called urban canyon environments, where the GPS signals are often blocked by highrise buildings and there are not enough available satellite signals to estimate the positioning(More)
The potential eld method is widely used for autonomous mobile robot path planning due to its elegant mathematical analysis and simplicity. However, most researches were focused on solving the motion planning problem in a stationary environment, where both targets and obstacles are stationary. This paper proposes a new potential eld method for motion(More)
