Tomáš Vávra contributed to the RoboticsBrno/Robutek repository by delivering hardware and documentation improvements focused on manufacturability, reliability, and production efficiency. Over six months, he redesigned the Zelvicka PCB using KiCad, optimizing footprints, net names, and USB routing to align with KiCad 8 and streamline assembly. He addressed I2C interface issues, standardized component footprints, and automated JLCPCB assembly file generation with Makefile-driven workflows. His work included schematic data governance, BOM accuracy, and detailed technical documentation using Markdown. These efforts reduced production risk, improved hardware integration, and enhanced onboarding materials, demonstrating depth in electronics engineering, PCB design, and hardware development.
