Excavator control simulation system

Abstract

OCR 07AP This invention relates to an excavator control simulation system comprising a driver's cab structure, a control computer, a mixed-reality headset, and a virtual reality scene. The driver's cab structure is designed with a seat, canopy, and excavator control components modeled after a real excavator. The excavator control components include at least a gear lever, pedals, and a blade lever for virtual excavator control. The control computer is signal-connected to the excavator control components to input and process excavator control data. The control computer is also signal-connected to the mixed-reality headset to display the processed images. The virtual reality scene is used to display virtual images on the headset and is mounted around the driver's cab structure, providing at least a 180-degree field of view for the driver to see the entire simulated front view.
