Abstract

In Public health, environmental protection, and urban infrastructure, road cleanliness is ensured. Traditional manpower- based sweeping methods are inefficient and unsuitable for larger areas. This project deals with the design and development of a semi- automatic road sweeping system. The developed system includes mechanical architecture and embedded control that makes the cleaning more efficient and faster. It also does not require too much manual effort. The proposed system consists of 12V high-torque DC gear motors, which are provided for a four-wheel drive. It can move in multiple directions. A brush motor is provided, which will rotate above the surface for cleaning dust and debris from the surface. A relay module that facilitates manual and semi-automatic operation of motors is still a control unit based on an ESP32 microcontroller. A 12V, 7Ah lead-acid battery powers the system, which is portable and operational. According to tests, the robot has stable mobility, cleaning efficiency on dry surfaces, and system performance. The robot speed is around 1.3 km/h with a run time of 45–50minutes. Compared to conventional methods, the suggested system consumes less human effort with better cleaning. The prototype that was developed can be used on urban roads, highways and industrial locations and is compact and cost-effective, and easily scalable to demand. The prototype can also be IoT automated and made smart city compatible.
