README
README.mdROBOT CLAIRE
This project is the result of three years of development from my high school years. The main goal was to build my own robot from scratch, without using common construction parts that are readily available in many hobbyist shops today.
At the time when I was creating my robot, open-source CAD programs weren’t at a
sufficient level to design something that could be sent to a factory for
fabrication. For this reason, the mechanical design was created using Inventor
2013, while the electronic design was done using KiCad. The project has already
gone through three upgrades, but the first one wasn’t documented. However, I
did take some photos to capture the atmosphere of the very first steps in
development (claire-rev0).

In the following folders, you will find README.md files with more detailed descriptions of the content. Some folders also include additional information, such as installation and execution instructions, particularly in directories containing software. Please note that this repository is still under development, and not all folders have been fully uploaded yet.

Questions
How big is the UNICON board PCB?
It measures 127 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UNICON board use?
132 parts, built around the ATXMEGA64A1-AU, PCA9551D and LF33CDT-TR. 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 UNICON board KiCad files?
From the dodotronix/RobotClaire repository on GitHub, at the commit this page was made from: the board is electronics/unicon/pcb/UNICON_board/UNICON_board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the UNICON board design in my own project?
Its repository states no licence, so its author keeps all rights: ask dodotronix before reusing the design.
