Sonia Lysok developed the initial firmware for pan and tilt servo control in the mcgill-robotics/rover-embedded-2025 repository, establishing the foundational hardware control layer for the rover’s pan and tilt capabilities. She used C++ to set up servo objects, configure pin assignments, define angle limits, and implement safe spin functions, ensuring reliable and safe operation. The firmware included serial communication initialization and a structured setup for attaching servos, with the main control loop prepared for future logic. Sonia’s work in embedded systems and firmware development enabled immediate hardware testing and provided a clear, maintainable pattern for future feature integration and iteration.
Month: 2024-11 — mcgill-robotics/rover-embedded-2025 Key features delivered: - Initial firmware for pan and tilt servo control, including setup for servo objects, pin assignments, angle limits, and safe spin functions. Serial communication is initialized and servos are attached in the setup; the main loop structure is prepared for future control logic. Major bugs fixed: - No bugs closed this month; focus was on foundational feature development and hardware initialization. Overall impact and accomplishments: - Establishes the foundational hardware control layer for rover pan/tilt capabilities, enabling immediate hardware testing and integration with higher-level navigation, imaging, and data collection workflows. The implementation emphasizes safety with spin guards and a clear initialization sequence, setting the stage for rapid iteration in the next sprint. Technologies/skills demonstrated: - Embedded firmware development in C/C++ - Servo control and hardware abstraction - Pin mapping, angle limit configuration, and safe operation patterns - Serial communication setup and servo attachment lifecycle - Code structure suitable for a loop-driven control system and traceable via commits
