README
README.mdWolfieMouse
WolfieMouse is a robotics project to build a micromouse. This project covers three parts:
- Robotics algorithm for maze solving (C++)
- low-level hardware driver software (C and ARM assembly)
- Tools to capture and plot robot's sensor data (Python)
- Embedded hardware design and PCB design (KiCad, an open-source alternative to Altium)
This robot won:
- The Special Mention Award in 2018 IEEE Region 1 Micromouse Robotics Competition.
- The 3rd Place Award in 2019 IEEE Region 1 Micromouse Robotics Competition.
Get started
If you don't know what is micromouse competition, this document will help..
Requires tools:
- GNU Arm Embedded Toolchain and Makefile to build program for the robot.
- OpenOCD to upload the program to the robot and to debug.
- KiCad to design a PCB hardware.
Otherwise, a Vagrant virtual machine environment is provided to skip installing the above tools.
If you whish to start with this project, see get stared document.

Questions
How big is the Micromouse PCB?
It measures 100 × 74 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Micromouse use?
214 parts, built around the MAX14871EUE+, HCMS-2901, MPU-9250 and TPS73633DBV. 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 Micromouse KiCad files?
From the kbumsik/WolfieMouse repository on GitHub, at the commit this page was made from: the board is hardware/kicad_wolfiemouse/micromouse.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Micromouse design in my own project?
Its repository states no licence, so its author keeps all rights: ask kbumsik before reusing the design.
