Liugong Group has hundreds of dealers across the country. When selling equipment at each dealership, customers are unable to experience the equipment on-site due to the lack of appropriate conditions at the dealers' locations. In cooperation with Liugong Group, we offer VR software and hardware solutions. For the hardware, we customize the production of cockpits according to the machinery and simulate the manufacturing of operating equipment. In terms of software, we develop three scenarios based on the equipment's usage, namely mining, highway cleaning, and tunnel excavation. Our software-hardware solutions can effectively simulate the operation training of excavators and loaders.
