🔍 Project Overview

This project is a Duct Cleaning Robot with Remote Control designed to clean ventilation ducts, pipelines, and narrow industrial passages where manual cleaning is difficult or unsafe. The system is built using an Arduino Uno, motor driver modules, DC motors, and directional control switches.

The robot can be controlled using push-button commands that allow the operator to navigate the robot inside ducts and confined spaces. By pressing directional buttons, the robot moves forward, backward, left, or right to reach dust accumulation areas.

The robotic platform can also include rotating brushes or cleaning attachments to remove dust, debris, and contaminants from HVAC duct surfaces while moving through the pipeline.

⚙️ How It Works (Short & Simple)

🎮 Remote Control Operation

Directional push buttons send control signals to the Arduino Uno, allowing the operator to control robot movement inside the duct.

🤖 Robot Movement

Two DC motors controlled through motor driver pins allow the robot to move:

• Forward
• Backward
• Left
• Right
• Stop

🧭 Navigation in Ducts

The robot moves inside HVAC ducts and pipelines using wheels designed to travel through narrow and confined spaces.

🧹 Cleaning Mechanism

Rotating brushes or cleaning attachments mounted on the robot help remove dust, debris, and particles from duct surfaces.

⚡ Control Signal Processing

The microcontroller continuously reads button inputs using digital signals and activates motor outputs accordingly.

🛑 Safety Stop

If no control button is pressed, the robot automatically stops to prevent accidental movement.
