Balancing Robot Body

thingiverse

The 3D printed parts comprise a frame and wheels for a balancing robot. This frame is designed specifically for use with an Arduino Uno and NEMA 17 Stepper Motors. A comprehensive parts list has been included for the components used in my project. A motor control shield has also been created to accommodate two DRV8825 Stepper Motor drivers. The design for this shield can be found at https://www.thingiverse.com/thing:2830191. This design is not intended as a balancing robot instructional tutorial, but rather as a test bed for anyone looking to develop their own balancing robot. There are numerous excellent tutorials available online that provide detailed construction instructions and sketches for proven balancers. If you prefer to figure things out on your own, feel free to use or modify these files. I am happy to share the Fusion 360 files of the design with you if you wish to make modifications. This is my second attempt at creating a 3D printed balancer body frame, and I have incorporated several new features into this version. There is now room for an additional shield on the Arduino stack to accommodate future radio control. The shelves are designed to be removable, providing easy access to all components and facilitating motor removal. Notably, the distance between the centers of the wheels is approximately two times the diameter of the wheels. Please note that at the time of posting, this design has been shown to balance successfully.
