In this work, a physical simulation model of a 40-ton excavator is presented as an example for the virtual machine. However, virtual prototyping requires not only a detailed machine model, but also a driver model that computes realistic actuation signals during simulation. Therefore, a predictive driver model based on a state machine and ...

A hydraulic excavator is typically a tracked machine used for digging and moving dirt, rocks, and other materials. It has a long arm with a bucket on the end that can be used to scoop up and transport materials. A dozer, on the other hand, is a tracked machine that is primarily used for pushing and leveling materials.
