PROFILE
Cleo
Cleo Renaud developed and enhanced embedded flight control software for the EPFLRocketTeam/2024_C_AV_RPI repository, focusing on robust state machine design, modular driver architecture, and comprehensive test coverage. Using C++ and CMake, Cleo introduced new flight states, explicit failure handling, and centralized math utilities to improve system reliability and maintainability. The work included refactoring event semantics, stabilizing CI pipelines, and implementing a driver framework for hardware abstraction, enabling safer integration of sensors and actuators. Through systematic unit testing with the Google Test Framework, Cleo ensured accurate state transitions and policy enforcement, reducing operational risk and supporting future extensibility of the codebase.

Aug 1, 2025For 2025-08, EPFLRocketTeam/2024_C_AV_RPI delivered a focused enhancement to policy testing by implementing a PR_board policy check test suite, including a test helper class and fixture to systematically validate check_policy across initialization, error handling, manual mode commands, and state transitions. The effort, plus a minor formatting fix, strengthens PR verification, improves test reliability, and accelerates safe flight-state changes.

Mar 1, 2025March 2025 monthly summary for EPFLRocketTeam/2024_C_AV_RPI: Delivered a modernization of valve control and driver architecture, stabilized CI/test pipelines, and reduced integration risk. The introduced PR_board valve management enables per-valve command handling and state tracking while removing outdated interfaces, improving reliability and maintainability. The HDriver-based architecture standardizes driver interfaces and lifecycle checks, easing onboarding of new sensors and telecom modules. CI/test stabilization reduces flaky tests and accelerates feedback loops, contributing to faster feature delivery and lower release risk.
