Previous: Day 1 – Chassis and Motors
The Pi is essential as the heart and brain of the robot. This with the help of Gertboard which turns the Pi into an Arduino compatible device, is crucial for sending commands to the motors and servos.
The Pi runs Raspbian with an Arduino IDE or its command line alternatives. We also need minicom to send and recieve serial communication with ATMega chip in the Gertboard.
Insert SD card, power supply, and wifi dongle. Gertboard stacks up on top of the Pi connected to the GPIO pin headers.
We are running headless, i.e. no monitor, so make sure you can login to the Pi via SSH from your Ubuntu laptop.
The simplest communication is via Minicom program, however, in more advance setup, you can write a nice GUI or a website for the command control panel.
