Design and Fabrication of Vertically Wall Climbing Glass Cleaning Robot
A robot that climbs vertical glass walls and cleans them. A centrifugal impeller creates suction to hold it to the glass while it moves, and brushes or wipers clean the surface, reducing risky manual cleaning of tall buildings.

How the Design and Fabrication of Vertically Wall Climbing Glass Cleaning Robot works
- 12 V power adapter / step-down transformer supplies the circuit; a regulator gives the controller and sensors a steady 5 V.
- The Arduino Uno R3 reads the inputs, runs the decision logic written in C/C++ and drives the outputs.
- The Mini submersible water pump moves water for irrigation, dispensing or cooling.
- The DC geared motor provides the driving motion.
- The Motor driver lets the low-current controller run the motors forward, reverse and at variable speed.

E&TC / ECE viva questions on this project
What is the aim of the Design and Fabrication of Vertically Wall Climbing Glass Cleaning Robot project?
A robot that climbs vertical glass walls and cleans them. A centrifugal impeller creates suction to hold it to the glass while it moves, and brushes or wipers clean the surface, reducing risky manual cleaning of tall buildings.
Explain the working of your project in short.
12 V power adapter / step-down transformer supplies the circuit; a regulator gives the controller and sensors a steady 5 V. The Arduino Uno R3 reads the inputs, runs the decision logic written in C/C++ and drives the outputs. The Mini submersible water pump moves water for irrigation, dispensing or cooling. The DC geared motor provides the driving motion.
What microcontroller is on the Arduino Uno and what are its key specifications?
The Uno uses the ATmega328P: 8-bit, 16 MHz clock, 32 KB flash, 2 KB SRAM, 14 digital I/O pins (6 PWM) and 6 analog inputs with a 10-bit ADC.
How is the pump switched by the controller?
Through a relay or MOSFET, because the pump runs at 12 V and draws more current than the controller pin can provide.
Why is a geared motor used?
The gearbox reduces speed and multiplies torque, so a small DC motor can move a vehicle or mechanism smoothly. Torque increases roughly by the gear ratio.
Why can't the motor be connected directly to the microcontroller?
A motor needs far more current (hundreds of mA to amps) than a controller pin can supply (about 20–40 mA). The H-bridge driver switches the motor current and allows direction control.
How is 230 V AC converted to 5 V DC for the circuit?
A transformer steps down the voltage, a bridge rectifier converts AC to pulsating DC, a capacitor smooths it and a 7805 regulator gives a steady 5 V.
Explain the block diagram of your project.
The input section senses the real-world quantity, the Arduino Uno R3 processes it according to the program, and the output section displays the result and drives the actuators. The power supply section feeds every block.
Which communication protocols are used between the modules?
Analog inputs read by the ADC for the analog sensors. Each protocol was chosen because the module supports it and it uses the fewest pins.
What is the operating voltage of the circuit?
The controller and most sensors work at 5 V (ESP boards and some modules at 3.3 V). The battery powers the board, and a regulator steps it down. Motors and relays get their own supply line so they do not reset the controller.
Is your system open-loop or closed-loop?
Mainly open-loop: the controller runs the actuators for a set time or number of steps. Adding a sensor for feedback would make it closed-loop and more accurate.
