TriangleDigger is a real-time computer simulator of crawler excavator. It allows to perform basic activities of excavator such as digging, dumping soil and driving on terrain. During the simulation physical models of excavator and terrain are used. The results are presented in 3D visualisation.
An additional part of the project is the steering device, which is an USB peripheral. Thanks to it, controlling the excavator is more complex and similar to real, and also provides more pleasure, as compared with operating using only keyboard.
