This paper presents design and development of an automatic touchless carwash system. The proposed system offers quick, convenient, and efficient carwash services. The steps involved in the car wash process consists of car peripheral mapping, adjustment of nozzles based on car peripheral mapping, and washing process. In the first step, object mapping is accomplished using appropriate sensor system. Subsequently, data acquired from sensors is processed and the relevant information regarding car periphery is stored. Finally, the position of the nozzles is adjusted (at appropriate position/angles) based on the car peripheral mapping. Once the nozzles are adjusted to appropriate angles, the washing process is initiated that includes foam spray, water spray and drying. In this paper, the simulation model of the proposed mechanical design of the system is firstly created in fusion360; followed by the development of a small-scale hardware prototype. With the intelligence incorporated in the design, the developed system is capable to consider the peripheral dimensions of objects for effective washing process.
