Pure Pursuit Controller
Introduction to Motion Planning Motion planning is a core component of autonomous robots that deals with finding and following a path for the robot to reach a goal safely. High-level (global) motion planners typically compute a static path through the environment, but real robots operate in dynamic environments where obstacles or conditions can change rapidly. […]
