The model works much like a video game: A user plugs in commands to, for example, move the simulated rover forward a certain distance — instructions similar to those that NASA engineers give to rovers on Mars. The simulation then predicts how the rover will move, based on the underlying soil properties, vehicle characteristics and a terrain’s incline.
