Self Balancing Robot Development Platform ( Fusion 360 design files included )

thingiverse

This is my in-progress self-balancing robot development platform that I designed with modularity in mind to make customization and building easier for various purposes. The parts were all made with standard tolerances for PLA, except for the tires which are meant to be printed in TPU or a flexible material. Most holes are 2.5mm for M3 bolts unless specified otherwise by a component. I drew inspiration from a popular design made out of laser-cut plywood and can be found here: http://www.brokking.net/yabr_main.html The electronic component designs were sourced from GrabCAD. I've included the Fusion 360 design files so you can modify the robot design to suit your own needs. In its current configuration, there's enough room for a Pi Zero W and an Arduino Nano, steppers, one arm servo, small camera, laser pointer, some sensors, LEDs, and two Nema 17 stepper motors. I used this size since it's the most common. My goal is to create a telepresence robot, but I may swap out the Pi for an Android phone, which would just require a different mount on top. You could build a very different robot. I've also included an exploded parts diagram as well as an X-ray view from within Fusion 360 and a render with the front lid off. I'm open to suggestions, feedback, and criticism, and I'll post photos as it gets built. When I have code up, I'll share the GitHub link. --UPDATE 1/10/18-- I've printed the wheels and tires and adjusted them for a perfect push fit with most PLA. You should be able to push the wheel onto the axle without using tools or glue, and still have it be nice and solid. Please download the new wheel file and CAD drawing if you had downloaded the old one.
