Unmanned Vehicles for Agricultural and Off-Highway Applications

Two unmanned vehicles were designed for agricultural and off-highway use. The vehicles lack a cockpit and related accessories. They are initially guided by a video-assisted remote control system - a self-guiding system, which consists of an RF-based positioning system and a digital guidance module, is under development. Both vehicles are propelled by hydrostatic drives and hub motors. Traction is provided either by rubber tracks or a four-wheel-drive/four-wheel-steering system. The vehicles combine very low weight, small dimensions and agility with high drawbar pull and rough terrain capability. They offer potential for a high degree of automation and precision especially in agricultural use.
