Ground pressure is recognized as an important constraint on a demining vehicle, becuase ground pressure is what disturbs the ground and triggers many land mines. If a demining vehicle is to safely traverse a minefield, it must exert as low a ground pressure as possible. Preferably this would be lower than the minimum pressure value which would detonate a mine.

Ground pressure of a vehicle can be considered a conplex function of vehicle parameters, tire properties, and soil characteristics. Due to the complex nature of this function, obtaining an accurate calculated value for ground pressure is difficult.

This ground pressure measurement device is an experimental device which can measure ground pressures of vehicles (or people), as it would be experienced by a land mine.
