ROBOT SPEEDS CRACK FIXING JOBS

This article describes a computer-guided system for sealing cracks in pavement. After nine years of development the results indicate that this robotic system can seal cracks almost as fast as four human workers. The system is being implemented at the Texas Department of Transportation in Austin. By tracing the cracks on a video screen, a robotic arm is instructed to blow, fill, and squeegee the cracks in a single pass. The system moves three times faster than conventional sealing methods and is more cost effective.
