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.

STRUCTURAL DESIGN :
n Special attention needs to be paid to the design of linear slides for smooth and proper operation.
n Roller wheel are used for smooth running in presence of dust and dirt.
n Low maintenance
n Lower wheel is used to provide clamping force due to moment produced by the compression rings to ensure straight line motion
