Mini Chaindrive Robot

# Remark
This is a first version and **work in progress**. I am trying to get everything to work together. I will comment my current state of progress and current issues and keep updating.

# Idea
A few years ago, I bought an Arduino Robot kit which was using two simple gear motors and a L298N motor driver. It has an acrylic plate as chassis and a third free rotating wheel. Nice to experiment with it. But really boring design. So while watching Ivan Miranda on Youtube, I got the idea to give it a chain drive and convert it into a "micro tank".

#Plan
- Use the motors and electric components of the kit
- Arduino Nano as Brains
- Make it small enough to be printed on almost any printer
- Make it remote controlled via Bluetooth
- Autonomous mode driving using an ultrasonic range finder to detect obstacles

# Parts
**Chassis (half):** Tested. Position for motor holes slightly adjusted. Checked with second half. Fits fine now.
**Chassis lid:** Tested. Motors were in the way.
