Jun 1, 20252025-06 Firmware monthly summary for CU-Robotics/firmware: Delivered three primary features, fixed critical reliability bugs, and strengthened safety controls, delivering measurable business value through safer, more reliable autonomous operation. Key features: TargetState Data Transmission across components with serialized data and accompanying usage documentation; Feeder Control Reliability and Safety Enhancements including improved encoder reporting, direct switch-driven target acquisition, and a timer-based readiness delay to reduce race conditions; Hive Mode Safety Toggle and Governor Update implementing a safety toggle with state reset and governor reference adjustments when entering hive mode. Major bug fixes: improved Damage Status Transmission Reliability by updating state only on changes and refining angle normalization and defaults; Teensy Mode Safety Guard to prevent overrides during inspection; and a targeted fix to chassis angle wrapping observed in damage transmission. Overall impact: reduced telemetry noise, fewer race-condition-induced failures, safer mode transitions, and clearer data contracts; Documentation and commit discipline support faster onboarding and maintenance. Technologies/skills demonstrated: embedded firmware development in C/C++, serialization and cross-component communication, state machines and safety engineering, debugging and issue-focused remediation, and thorough documentation practices.
