Autonomous Vehicle Waypoint Navigation Using Hyper-Clothoids
… strategy, to autonomously navigate a car. These waypoint navigation solutions smoothly connect the given waypoints with C1 continuity using Hermite cubic splines which is used as a reference path for the controller to track. The PID controller uses lateral and heading error to generate a steering …

Design and Development of an Autonomous Line Painting System
… Global Positioning System (GPS) coordinates for waypoint navigation. A computer vision algorithm is developed to provide vision feedback to stabilize the painting mechanism. The system is demonstrated to follow an input desired trajectory and cancel any high frequency vibrations due to the uneven …
