Diversification and sophistication

In this report, progress and state-of-the-art of research on vehicle and machinery designs are described for vehicles such as boat tractors, wheel type vehicles, tracked vehicles and a new locomotion system. The development stages and aspects of off-road vehicles are different in countries/districts, showing many kinds of running devices. Reflecting a high-technology in some countries, the mechanism and the control system of off-road vehicles are becoming more and more sophisticated.
