The “Climbing Clean” robot is an innovative stair-climbing robotic system designed to perform cleaning operations efficiently across multi-level environments. The system is built around an ESP32 microcontroller with integrated Wi-Fi capability, enabling real-time remote control and monitoring through wireless communication. The robot is powered by a battery and uses L293D motor drivers to control multiple DC motors responsible for forward/backward movement and vertical climbing using a gear-based mechanism. The robot is equipped with a specialized climbing mechanism that allows it to navigate stairs smoothly, overcoming one of the major limitations of conventional cleaning robots. In addition, relay-controlled subsystems are incorporated to operate a water pump for wet cleaning and a motorized mop mechanism for effective floor scrubbing. The integration of these features ensures both dry and wet cleaning capabilities. The Wi-Fi control enables users to operate the robot remotely via a mobile or web interface, making it suitable for modern smart environments. This project provides a practical solution for automated cleaning in homes, offices, and public spaces with staircases, reducing human effort and enhancing efficiency. Future improvements can include automation, obstacle detection, and AI-based navigation for fully autonomous operation.
