Design And Experimental Research Of Waterless Car Washing Robot System

As the most common mode of transportation,cars have entered thousands of households.The car ownership has become an important indicator of a country’s development.At present,the domestic and foreign auto service industries mainly use manual car washes and automatic car washes to wash cars.There are problems such as low efficiency,waste of water resources,environmental pollution,and poor flexibility,which seriously hinder the development of the auto service industry.In response to the needs of the modern automobile service industry for high efficiency,water saving,pollution-free,intelligent and other industries,the development of efficient and energy-saving automatic car washing robots is urgent.Taking the development needs of the automobile service industry as the starting point,this paper proposes a high-efficiency and high-flexibility waterless car washing robot design scheme for traditional car washing methods such as low efficiency and poor flexibility;by combining statics,dynamics,The methods of cybernetics and computer simulation have conducted in-depth research on key issues such as functional design,structural design,and multi-sensor fusion of the waterless car washing robot.The main research contents are as follows:(1)The structure design of the waterless car washing robot.Analyze the development needs of the automobile service industry,propose a design scheme for a waterless car washing robot,and complete the design of the robot body structure.Based on the self-adaptive cleaning design proposed in this paper,a force-adaptive brush system and self-cleaning device are designed.The main force-bearing parts of the robot are analyzed statically to ensure the reliability of the structure.The dynamic modeling and simulation of the force-adaptive brush system is carried out to determine the feasibility of the force-adaptive cleaning of the brush.(2)The design of the control system of the waterless car washing robot.Using a modular design idea,the control system is divided into a position detection module,a motion module and a cleaning module,and an HMI interface is designed to control the movement of the robot.Complete the overall control scheme design of the waterless car washing robot,select the PLC type and I/O distribution,complete the hardware wiring and control flow design of each module.Finally,complete the software design of each module.(3)Experimental research on performance evaluation of waterless car washing robot.Build a functional test platform for the waterless car washing robot,complete the performance evaluation experiment of the force adaptive brush of the waterless car washing robot,verify the feasibility of the force measurement system,determine the optimal brush parameters and cleaning parameters,and verify the adaptive cleaning function feasibility.Complete experiments on lifting,telescoping,walking and turning of the waterless car washing robot to verify the flexibility of the robot’s movement.
