The probabilistic roadmap planner is a motion planning algorithm in robotics, which solves the problem of determining a path between a starting configuration of the robot and a goal configuration while avoiding collisions. The basic idea behind PRM is to randomly sample points from the configuration space of the robot, test the samples for whether they are in the free space, and use a local planner to attempt to connect these configurations to other nearby configurations.
