Sara Bhatnagar contributed to the nerdspark/2025_NERDSpark repository by centralizing servo position constants within the Constants.java file, standardizing hardware control values for embedded robotics systems. She focused on improving code maintainability by removing legacy, commented-out servo position code, which reduced technical debt and the risk of misconfiguration. Working primarily in Java and leveraging her skills in embedded systems and robotics, Sara’s changes enabled safer and more maintainable hardware integration, aligning with the team’s planned servo automation efforts. While the scope was limited to a single feature, her work laid a foundation for cleaner, more reliable hardware control code going forward.
