By using FPGA (Field-Programmable Gate Array) technology it is possible to rule out the use of printed circuits for a specific process. In addition, process automation has been growing in the industry for financial returns and improved procedures. So, for the purpose of academic learning, it was proposed in the discipline of analysis and design of programmable logic systems of Electrical Engineering course at UFSM-CS the development of an automatic car wash system, usually found in gas stations, with autonomous execution. The project has two operation modules, where one module operates in a simplified way in the washing and the other mode is complete to obtain the effective cleaning of the vehicle. For system implementation, a code describing a state machine was developed in VHDL hardware description language., in which each state performs a system operation. A small scale prototype consisting of CD drives, stepper motors, DC motors and drivers has been developed.
