Abstract
In many fields, all terrain vehicles are highly demanded with high performance and efficient energy consumption. Some vehicles run on four or six tires, and some vehicles run rubber tracks, called crawlers. In this paper, we will focus on crawlers and their applications. First, we will describe the vehicle's features, and its characteristics. A unique four-wheel-steering Z link mechanism is applied. Crawlers with a tilting mechanism are applied that enables the vehicle to run over steps and obstacles.
