The Switch Sleeper Marking Robot is an automated identification and precision spraying device integrated into a robotic system. It is designed to automatically mark critical information—such as model type, location number, and installation sequence—onto railway switch sleepers (i.e., switch ties) in turnout areas. Essentially functioning as a mobile, intelligent “industrial spray coder,” it upgrades the traditional process—which relied on manual measurement and handwritten marking—to a fully automated, high-precision digital operation. This addresses the challenges posed by the complex arrangement of switch sleepers and the high error rate associated with manual marking.
