Adding a Rapberry Pi Zero onto the UK Mars Bot
]
NOTE:
The UKMarsBot is a maze solver and line follower, designed by the UK Mars and Robotics Society (UKMars). It has a Arduino Nano attached as the standard microcontroller.

This project aims to add a Raspberry Pi Zero to that basic design.
There is a provisional scope document here
There is a related seperate GitHub project for the Arduino Nano I/O coprocessor software: https://github.com/robzed/ukmarsey
There are two potential methods of connecting a Raspberry Pi Zero to the UKMARSbot:
- Produce an adapter board that converts the Pi Zero header to the Arduino Nano footprint, completely replacing the Ardunio Nano.
- Connect the Raspberry Pi to the Arduino over a serial interface to the existing Arduino Nano and use the Nano as an I/O processor.
This article will examine the second option since this is the simpler option to construct, without a custom PCB. (There are, however, some notes on method 1 provided in 'Replacing the Arduino Nano Entirely'.)
- UKMarsBot - tested working with Arduino Nano
- Arduino Nano v3 (or equivalent third-party Nano)
- Pi Zero v1.3
We will be using a Pi Zero (not a Pi Zero W which uses more power).
