Gantry Robot for Pavement Sign Painting Operations

Research Outline

Fig.1 Prototype of sign painting robot



The current method for pavement sigh marking operation is labor-intensive and very dangerous due to the exposure of workers to passing traffic. It also requires blocking traffic for a long period of time resulting serious traffic jam. This research deals with the development of a robotic system for automating the pavement sign painting operation. The robotic system consists of gantry frame equipped with transverse drive rail and automatic paint spray system. The workspace of the gantry robot is extended to one-lane width with the transverse rail system. This research also includes the development of font data structures that contain the shape information of pavement signs, such as Korean letters, English letters and symbols. The robot path is generated with this font data through the procedures of scaling up/down and partitioning the sighs to be painted depending on the workspace size.
