VR simulator for studying the structure of tractors

Year: 2023
Type: conference-paper
Abstract: The intensive development of agricultural engineering and agricultural technologies requires a future engineer to have thorough knowledge of the structure and purpose of modern agricultural machinery. In the educational process of training future engineers at higher agricultural educational institutions, the problem has arisen, which is the lack of such equipment as training models. Smart technologies of Industry 4.0, such as artificial intelligence, digital twins, virtual and augmented reality, allow to optimize the educational process, increase its efficiency and reduce the time spent on learning due to a new stage of automation. The purpose of the article is to highlight the main stages of VR application development and the possibilities of using virtual reality to study the structure of tractors. The main object of study is a tractor, so the issue of developing a digital twin has been resolved separately. The VR application has been developed as a smartphone program using a Google Cardboard headset, and the Unity game engine has been chosen as the development environment. The main scene shows a hangar with electronic models of a John Deere 6195M tractor and a virtual avatar. One model of the tractor is disassembled into separate components to study its internal structure. A script was written for the virtual avatar to allow it to move. In particular, the avatar moves when the camera is tilted down to a certain angle. Red markers are placed near the tractor units, which interact with the avatar’s sight and display information panels. The information panels tell about the name of the unit, its purpose, and technical characteristics. The capabilities of the developed program have been tested on a sample of students, which included 53 applicants of the speciality 208 Agroengineering. During teaching the Technologies and means of the agroindustrial complex discipline, a practical lesson was developed where students studied the structure of the John Deere 6195M tractor and the controls located in the cab. Evaluation and measurement of user perception of the developed virtual reality application has been determined by a survey based on a questionnaire on technology acceptance. The data obtained using the Likert scale have been analyzed by calculating the mean, median, and standard deviation. The median is close to the mean. This fact indicates a normal distribution of responses, meaning that most respondents rated the mobile application about the same. The results of calculating the standard deviation have shown that these indicators do not exceed one. This indicates the homogeneity of the respondents’ answers, which are close to the average value. The use of the program we developed in the educational process has shown that higher education students liked the process of gaining knowledge in the game form, but it should be noted that the movement of the virtual avatar sometimes caused dizziness in some users.
