Welcome to the 2018 linux.conf.au Open Hardware Project. You can see information about this and other MiniConfs at http://www.openhardwareconf.org/wiki/Main_Page.
If you're attending the assembly workshop at Linux.conf.au 2018, the place to start is http://www.openhardwareconf.org/wiki/LoliBot
This year's project is called the Lolibot, and is a simple robot is designed to chase and kick a Ping Pong ball around.
It features a Lolin32-lite ESP32 based chip as it's primary microprocessor and includes a MPU6050 6 axis accelerometer.
In order to reduce complexity and to be a bit more flexible with our design this years project is a platform with discrete components. Those of you who are looking forward to the smell of melting solder won't be disappointed though, there are many headers, LEDS and switches to keep you busy.

Software
All the usual ESP32 development options apply to the LoliBot ...
- microPython scripts
- Arduino IDE sketches
- Native ESP-IDF FreeRTOS firmware
We've chosen to focus on using microPython to provide a simple, yet capable entry point for newcomers to robotics and embedded computers.
The software sub-directory has instructions on installing and developing software for the LoliBot.

Questions
How big is the LoliBot PCB?
It measures 146 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LoliBot use?
42 parts, built around the MPU-9250. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LoliBot KiCad files?
From the CCHS-Melbourne/LoliBot repository on GitHub, at the commit this page was made from: the board is LoliBot/LoliBot.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LoliBot design in my own project?
Its repository states no licence, so its author keeps all rights: ask CCHS-Melbourne before reusing the design.
