This document discusses the application of robotics for path planning. It begins by defining robotics and describing some common applications of robots, such as jobs that are dirty, dull or dangerous. It then focuses on path planning, which allows robots to find optimal paths between two points using a map of the environment. Several path planning algorithms are described, including Dijkstra's algorithm, A*, D* and RRT. Map representations like occupancy grids and topological maps are also discussed.
