Robot Path Planning Using Artificial Potential Field Method

The Artificial Potential Field method is a widely adopted approach for robot path planning. This technique operates on potential field principles, creating virtual repulsive and attractive fields around obstacles and targets respectively to guide robotic movement along desired trajectories. The implementation typically involves calculating gradient vectors derived from potential functions, where obstacle repulsion forces and goal attraction forces are balanced to generate smooth collision-free paths. Key algorithmic components include distance-based potential calculations, vector summation for motion direction determination, and velocity control for stable convergence. Validated through practical applications, this method demonstrates significant advantages in real-time obstacle avoidance while maintaining high path planning efficiency.
