A remoted Caterpillar D4 bulldozer, interfaced to the ROBOCON system. The goal will be to use the platform as a heavy earthmoving system to train IUOE operators and to experiment with human factors parameters to optimize human performance. The ultimate goal is to compare the performance of a human operator sitting in the same machine to that of a remotely-located operator with simple visual and numeric feedback, motion-platform chair, etc.
