Abstract
Application of raised pavement markers is a simple but dangerous operation. In a common scenario, an operator sits in a specially designed bay of a slowly traveling truck and manually applies bitumen with a hand-controlled dispenser and places a marker on the bitumen while traffic is passing only a few feet away. A telerobotic raised pavement-marker applicator that uses the capabilities of advanced technologies to automate the tasks of selection of markers, placement of markers, and dispensing of bitumen is described. Most importantly, the operator is moved from the truck bay into the passenger side seat and observes and controls the entire process with a video interface system. A PC-based microcomputer provided the platform that allowed efficient integration of the pneumatic and hydraulic actuators necessary to place markers remotely.
