How to Build a Simple Arduino-Based Robot that Cleans Your House

Building a simple robot that can clean your house using an Arduino is an exciting project that can be done with basic electronics knowledge and some DIY skills. Here is a step-by-step guide on how to build your own Arduino-based cleaning robot:

Gathering the Required Components

To build the robot, you will need the following main components:

Assembling the Robot Chassis

The chassis provides the base on which you can mount all the components. If 3D printing a chassis, make sure to design appropriate mounts and wire routing. For an RC car, you may need to remove unnecessary parts and modify it.

Key aspects in assembling the chassis:

Connecting the Motors and Motor Driver

Interfacing the Sensors

The sensors provide the robot vital information about its surroundings:

Connect the sensor outputs to the Arduino inputs using jumper wires. The trig and echo pins of an ultrasonic sensor need to go to separate digital pins. Take note of which Arduino pin is connected to each sensor.

Programming the Arduino

The Arduino code controls the robot behavior by:

The core functionality is:

Assembling the Complete Robot

With the individual components tested, assemble the complete robot:

Testing and Troubleshooting

With the robot fully assembled, thoroughly test it:

With careful assembly and incremental testing, you will have an Arduino-powered cleaning robot ready for action! The key is taking it step-by-step.


Building a home cleaning robot with an Arduino provides an excellent learning experience in robotics. The skills gained such as planning, 3D design, electronics, programming and problem solving can be applied to tackle even more advanced robot projects in the future. With the right components, tools and techniques, anyone can bring an autonomous cleaning assistant to life using the Arduino platform.
