1 Autonomous Turf Mowers
Travis McMahan

2 Achieving Automation Reliable obstacle detection
Must be able to find obstacles as small as a golf ball, while not generating false positives Must detect obstacles to keep the vehicle safe (bunkers, ponds, cliffs) Operate with cm level precision to create the stripe patterns seen on elite golf courses Must be able to create patterns that cover the entire fairway in an efficient manner

3 Toro Triplex

4 Avoiding Obstacles INS/GPS systems
Inertial sensors measure velocities and accelerations 3-D cloud image POS-LV system Sick laser scanner provides obstacle detection and mapping

5 color segmentation, distinguishes obstacles based on color
stereo based homography to detect objects which lie above the ground plane color segmentation, distinguishes obstacles based on color backup detection system
