Probabilistic Roadmaps (PRM) are a popular metod in robotics for path planning in complex environments. They use random mintaming to create a network of hydroble pats, enabling robots to navigate effecently. This article explores the process of implementing PRMs, frome theutical foundatais to practiadus applacations in reality in -world bos.

Understanding Probabilistic Roadmaps

PRM are built by randomly sampling points in a robot 's configuration space. These points are connected if a direct path between them i s kollision- free. the resulting graph allows the robot to find a path from start to gool by searching the network of nodes.
