Abstract

Vehicles and UGV(Unmanned Ground Vehicle) need a variety of road informations, such as road profile, soil type and soil water contents, to run a cross country course. Especially, soil water contents are very important factor to judge the vehicle mobility, because it can change soil strength. This paper describes the real-time measuring method of soil water contents by using the soil thermal conductivity.

Key Words: Soil Water Contents, Soil Thermal Conductivity, Vehicle Mobility
