Effects of grouser movement to sand-grouser interaction on unconsolidated soft sand incline using discrete element method (DEM) simulation

Wheeled rover is a lightweight robot that is used for driving over rough terrain such as on unconsolidated sandy dune incline. Typically, a rover is equipped with fixed grousers on its wheels (conventional grousers). A problem that usually occurs by using conventional grousers is the rover getting...
