Abstract: The conventional method of cleaning blackboards is time-consuming and often produces considerable chalk dust, which can affect classroom cleanliness and the health of students and teachers. This project presents the design and development of a mechatronic system for automatic blackboard cleaning that integrates mechanical, electrical, and control components to automate the cleaning process. The proposed system consists of a motordriven cleaning mechanism, suitable wiping material, guide rails, sensors, and a microcontroller-based control unit. When activated, the system moves the cleaning mechanism systematically across the blackboard surface to remove chalk marks with minimum human effort. The design aims to provide uniform clean-ing, reduce dust generation, improve operational efficiency, and minimize cleaning time. The developed prototype is evaluated based on cleaning effectiveness, operating time, power consumption, and reliability. The proposed system offers a simple, economical, and user-friendly solution for educational institutions and demonstrates the practical application of mechatronics and automation in classroom environments.
