Zachary Ethridge developed and enhanced the Cyclone-Robosub/Propulsion_2024_CPP propulsion software, focusing on reliability, maintainability, and simulation fidelity. Over two months, he restructured the command framework using object-oriented C++ and expanded the physics stack to support six-axis force and torque computations, improving model realism for robotic propulsion. He implemented PWM-based movement control, introduced drag force modeling, and improved cross-platform stability with build system and Windows compatibility fixes. Ethridge also strengthened testing by refactoring unit tests and addressing regression issues, while enhancing documentation and code clarity. His work demonstrates depth in C++, build systems, and embedded robotics software engineering.

Dec 1, 2024December 2024 — Cyclone-Robosub Propulsion_2024_CPP: Targeted bug fix and observability enhancements to improve thruster control reliability and debugging efficiency. A critical bug in Thruster_Commander was resolved by correcting the thruster position coordinate, stabilizing command generation. A debug information print was added to the main function to surface thruster state during runs, enabling quicker diagnosis in development and field scenarios. The related Thruster_Commander_Testing.cpp test was noted to be potentially recursive and was commented out, requiring future review. Overall impact includes more accurate propulsion, reduced field risk, and enhanced diagnosability. Demonstrates strong debugging, testing discipline, and instrumentation skills in C++ and embedded systems.

Nov 1, 2024November 2024 delivered a major propulsion software refresh for Cyclone-Robosub/Propulsion_2024_CPP, focusing on reliability, realism, and maintainability. Key features include a new command framework with an improved OOP structure and prototypes for simple movement commands, plus movement control enhancements that emit PWM signals and introduce drag force prototypes. The physics and thrust stack was expanded with comprehensive six-axis force/torque computations, drag torques, velocity modeling, drag coefficients, and clearer thrust function naming, enabling more accurate simulations and control. Quality and consistency improved through unit-test restructuring (separate test file), regression fixes to enable unit tests in the main block, and multiple build/header hygiene fixes across the codebase. Cross-platform stability and documentation also improved, including YAML constructor support, Windows portability fixes, and ongoing documentation/comment updates. Together, these outcomes reduce build churn, improve model fidelity for flight propulsion, and accelerate future feature work while elevating overall code quality.
