A screw-propelled vehicle is a type of vehicle that moves using a large rotating screw or similar mechanism instead of wheels or tracks. The rotating screw acts like a large, spiraled blade that pushes the vehicle forward by digging into the surface below. These vehicles are typically used in areas where traditional wheels or tracks might not work, such as deep snow, sand, or soft mud. Screw-propelled vehicles are built to travel on challenging terrains, offering an efficient way to move over surfaces that other vehicles may struggle with.
