Building your own robot that can clean your house is an exciting DIY project that doesn't have to cost a lot of money. With just a few affordable parts and basic coding skills, you can create an Arduino-powered cleaning robot using common household materials. Here's a step-by-step guide to building your own affordable DIY cleaning robot.

Introduction to Arduino Robotics

Arduino is an open-source electronics platform that allows you to create interactive devices with sensors and motors. Here's a quick overview of Arduino robotics:

The Arduino ecosystem makes it simple to prototype and build robotics projects using these basic electronic components.

Planning the Robot Design

Before building your Arduino cleaning robot, you need to plan out your design:

Constructing the Chassis

The chassis provides the frame or body of your cleaning robot. Here are some options for constructing a simple do-it-yourself chassis:

Wooden Platform Chassis

Box Frame Chassis

Repurposed Materials

Make sure to sand edges smooth and avoid leaving nails or screws protruding that could scratch floors. Also ensure the chassis is balanced; the battery often helps weigh down the rear.

Mounting the Motors and Wheels

DC motors drive the robot's wheels to move it around your floors. Here are some DIY options:

Use a motor controller circuit between the Arduino and motors to handle power requirements. Make sure to align the wheels straight and space them apart adequately for stability.

Adding Sensors to Navigate

Sensors give the robot "eyes" to see and navigate around obstacles:

Attach the sensors firmly pointed in the proper direction. Run wires neatly along the interior sides back to the Arduino. Take care soldering the thin wiring of the sensor components.

Programming the Arduino

The Arduino code brings your robot to life by controlling the logic and movement:

Start with simple code to make the motors spin and build up to navigating with sensors across the room. Troubleshoot any wiring or syntax issues as you test the code.

Constructing the Cleaning Mechanism

To automate floor cleaning, you need to attach a sweeper, duster or other cleaning tool:

Make sure any cleaning components are firmly affixed and do not block sensors. code can activate the cleaning mechanism when the robot senses it is over debris or dirty floors.

Powering the Robot

The Arduino and motors require sufficient power from a battery source:

Include an on/off switch to cut power. Monitor battery voltage periodically since maximum motor current draw can quickly drain batteries.

Assembling the Complete Robot

With the main components fabricated, it's time to assemble your DIY cleaning robot:

The final assembly step is attaching your cleaning tool like a rotating sweeper. Power it on and watch your completed robot come to life!


Building a DIY Arduino robot that can roam around and clean your floors is an achievable weekend project using common components and basic robotics skills. Following the tips in this guide about constructing the chassis, drivetrain, sensors and cleaning mechanism, you can have your own affordable cleaning robot up and running in no time!
