README
README.mdTwo Wheel Self Balancing Mobile Robot
Final Year Capstone Mechatronics Project. Designed to be a cost effective platform for research and development of autonomous mobile robotics. The non linear and unstable dynamics of the Two Wheel Self Balancing Mobile Robot (TWSBMR) make it a challenging platform for control and navigation.
Low Level motor control implemented on STM32F411RE microcontroller, using LibOpenCM3. High Level Monocular Navigation uses RaspberryPi 5 with the Pi Camera V3. ComsTerm used as engineering UI.
Design
The project was built around milestones of autonomy:
- Stabilization
- Positional Control
- Teleoperation
- Path Following
- Path Recovery
- Track Racing

Questions
How big is the PiCardZW PCB?
It measures 70 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PiCardZW use?
19 parts. 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 PiCardZW KiCad files?
From the Wrodders/dBot repository on GitHub, at the commit this page was made from: the board is Hardware/PiCardZW/PiCardZW.kicad_pcb and its schematic Hardware/PiCard5/PiCard5.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PiCardZW design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
