Chloe Zhong developed and integrated a watchdog timer system for the stanford-ssi/samwise-flight-software repository, focusing on enhancing fault tolerance and system reliability in embedded flight software. She designed a new driver and dedicated task in C, initializing the watchdog at system startup and implementing periodic feeding to maintain system liveness. The integration required updates to the build process using CMake and careful attention to CI/CD workflows. By wiring the watchdog mechanism into the core system, Chloe addressed the risk of software hangs during autonomous operation, contributing a robust solution that supports safer, more predictable behavior in mission-critical embedded environments.
