Mechanical Design of a Robotic System for Automatic Installation of Magnetic Markers - blackdalia - 10-04-2017 Mechanical Design of a Robotic System for Automatic Installation of Magnetic Markers on the Roadway MAGNETIC REFERENCE MARKER INSTALLATION : n Involves drilling the roadway surface. n Stacked ceramic magnets and neodymium magnets require hole depth that are just 10.1 cm and 2.5 cm. n Vehicles depend on the magnet for speed detection and lateral road position.
