“Your Arduino Balancing Robot (YABR) is a self-balancing robot that you can build yourself as a school project or as a fun project with your kids. It might look simple but there is a lot that you can learn from building this self-balancing robot. In contrast to most self-balancing robots, this one uses stepper motors instead of regular DC motors. The main reason is that stepper motors are precise and have no performance loss when the battery voltage drops. One pulse is always an exact amount of motion. Regular DC motors can have mechanical friction and electric resistance differences. This can cause performance differences. As a result the robot will not move in a straight line. The total cost to build this robot is approximately $80 if you use the hardware list below. This includes a battery, Nunchuck, charger, stepper motors, etc. The Arduino program that you can download for free is 100% self-written and not based on any other software. The code is well commented and clearly explained. This makes it possible to further develop the code for your own purpose.”
