Robots that can stay in balance on 2 wheels are called balancing robots or self balancing robot. Moving the robot on 2 wheels results in it starting to fall forward or backward. But the robot can resist this fall with the information it receives from the acceleration and gyro sensor.

Balance robots use basically the same few materials. These are; 2 motors (DC, step motor, 2 wheels, battery, sensor for balance (usually gyro sensor) and microcontroller (mostly arduino).

Some projects in the list were used Raspberry Pi. Arduino has lower capabilities according to Raspberry Pi. Some functions like image processing, video record need Raspberry Pi.

Before I start a project, I examine the projects that have been done before. I suggest you do the same. If you have an idea to make a balancing robot, you should definitely review the following projects.

1- Simple and cheap self balancing robot

This robot is a balance robot made with the cheapest materials on the market. You should not expect very high performance from this robot. Cheap and non-reducer DC motors will affect a good performance.

By adding a joystick module to this project, you can provide a remote control feature. You can also control it with smartphone by adding bluetooth module

A simple and inexpensive balance robot with similar materials and similar features is also here. Moreover, this robot also has the ability to avoid obstacles using an ultrasonic distance sensor

2- Smart Phone Controlled Self Balancing Robot

The balance robot made by a youtube user named Tapendra Mandal is quite impressive. The Youtube video clearly shows how to do it. Moreover, the arduino codes of the project are also present in the video descriptions.

3- Different-looking self balancing robot

There’s a balance robot called Ascento that’s used for industrial work. An open source project similar to ascento’s appearance was posted on the Pro Know youtube channel. Moreover, the materials used can be bought cheaply and can be found everywhere.

4- Super fast 3d printed self balancing robot: B-Robot

Everything you’re looking for is also B-Robot. If you are looking for an open source balance robot with 3D models, codes and construction stages, this project is ideal for you. Increased speed is what attracts my attention the most. This robot is really fast.

Attention : 1:10

5- Very small- nano self balancing robot: Zippy 2.0

Zippy 2.0 is the smallest balance robot I’ve ever seen. In fact, it’s not so hard for a balance robot to be small. Small size balance robot can be made with Mini dc motors, small wheels, arduino mini and a thin li-po battery. But here the main issue is balance. A balance robot’s short stature brings some difficulties in terms of achieving balance. As far as I can see, Zippy has solved this problem.

Add: I found a smaller balance robot: Piddybot

 

6- Jostick controlled Open source self balancing robot

if you are looking for a great open source balance robot that you can control as you want with the joystick, this project is for you. The robot’s body is made entirely of wood. Even its wheels are CNC-cut. That’s one of the factors that reduces the cost of the robot.

7- Codesys Powered Self Balancing Robot

Unfornutally this self balancing robot is not open source. The reason I added this project to my list is because it has a more professional design than other robots. Bigger body, bigger wheels make this robot different. Also, Raspberry Pi and Codesys were used on this project.

Ramp climbing performance, video capture with the built-in camera on it is also one of the advantages of this robot.

8- Obstacle Avoiding Self Balancing Robot

Rasberry Pi was also used in this robot. The biggest reason for this, of course, is the camera module. Arduino is not available for high-capacity jobs, such as video processing.

4 arduino were used in this balance robot. One arduino Arduinos were used for distance sensors, one arduino for motor control, and one Arduino were used to receive information from the acceleration sensor. Raspberry Pi was also used to get video. This project needs a higher budget than other balance robots.

9- Simple 3D printed self balancing robot

Arduino was used as a control element in this balance robot, which is quite simple, simple, made of few materials. If you have a 3D printer, you should seriously consider making this robot.

If you like, the same website also has a balance robot that escapes the obstacle. You can also easily add this feature to your robot. The source website contains schemas and codes.

10- Balanduino- KickStarter Open Source Project

Balanduino is a successful kickstarter project. And it’s a completely open source project. Watch the video. If you also want to make a balanduino, you can browse the source websites below the video.

 

Conclusion in this article, we showed you 10 open source balance robots. It’s up to you to do one of them according to your budget, the facilities you have and your technical information.
