Description
Just another balancing robot... but with hair! :-)
Disclaimer:
This is not an advertisement, however this project was done for a company event.
Loewenfels Partner AG is a software development company in Lucerne Switzerland and one of their employee events usually features some kind of technical project to be build and programmed.

(Edit: sadly the video was set to private)
The bot is using stepper motors, an accelerometer/gyro and a pid loop programmed in Arduino IDE for an AtMega328p. The bot can be controlled using a Blootooth, i recommend 'Arduino Bluetooth RC Car' for Android (not tested with IPhone).
The source code and build instructions (german language only at the moment) can are there:

If you need more instructions just leave a comment :-)
The instructions to prepare the HC-05 module:
(from https://www.instructables.com/Modify-The-HC-05-Bluetooth-Module-Defaults-Using-A/)
set serial monitor in arduino ide to 9600 baud and connect
AT+ORGL
AT+VERSION?
AT+NAME=Bot red
AT+UART=57600,1,0
AT+POLAR)1,0
The code is structured this way it is as it was provided incomplete and had to be completed by the teams. Additionally it was my first arduino project (i'm a java programmer)...
It was designed mostly in Fusion 360 and for the skind/hairs OpenSCAD.
Fusion 360 couldn't handle the thousands of hairs, however rendering in openscad can take a few hours.
Bill of materials (BOM):
Print Time: About 24 hours
I used an Kossel XL and a 0.25mm nozzle
Material: PLA
The tire have to be printed in a flexible material (i used Nijaflex), or you can print tires and wheels as one part in PLA.
