Erik Kondor contributed to the UBC-Snowbots/Arm repository by designing and optimizing mechanical assemblies for a robotic arm, focusing on manufacturability, reliability, and integration. Over eight months, he delivered features such as axis-specific subassemblies, limit switch integration, and hardware enhancements like shaft couplings and shims. Using SolidWorks and CAD, Erik refined component geometry, improved assembly fit, and reduced weight through static analysis and parametric modeling. His work emphasized documentation, version control, and modular design, resulting in a maintainable codebase and streamlined onboarding. By addressing both hardware and documentation challenges, Erik enabled safer operation and accelerated future development cycles.
