PROFILE
Clyde Mcqueen
Over five months, contributed to ArduPilot/ardupilot by developing high-frequency IMU data logging and enhancing Position Hold (POSHOLD) control with RC-driven speed capping, both implemented in C++ and Python. Addressed cross-platform stability by restricting time API usage to specific hardware, and improved Surftrak mode by resetting rangefinder targets on disarm with added automated tests. Documentation was clarified for servo output constants, reducing onboarding friction. The work focused on embedded systems, flight control software, and robotics, emphasizing reliability, maintainability, and test coverage. Each change targeted real-world operational issues, with careful integration and parameterization to support robust, user-driven control scenarios.

May 1, 2025May 2025 — ArduPilot/ardupilot: Fixed Surftrak rangefinder behavior by resetting target on disarm and reacquiring after re-arm, with added autotest coverage. This eliminates stale data when motors are disarmed, maintains accurate range readings when armed, and improves safety and reliability of Surftrak mode. Commits included: 6215ab0f9eeb45fa3d95596c18d74ae4192b1fef; 7cfb84e30d5aeb263c48167341240ffde242f57a.

Mar 1, 2025March 2025: Delivered a focused bug fix to improve cross-platform time API correctness in ArduPilot. Restricted clock_gettime usage to HAL_BOARD_CHIBIOS, preventing its availability on SITL and ESP32 builds to avoid misconfiguration and potential runtime errors. This reduces platform-specific runtime failures, simplifies build configurations, and enhances overall system reliability across supported boards.

Dec 1, 2024December 2024 Monthly Summary for ArduPilot/ardupilot focused on stabilizing and parameterizing Position Hold (POSHOLD) control with RC-driven horizontal inputs. Key features delivered: - Position Hold Pilot Speed Cap and RC-driven Horizontal Control: added PILOT_SPEED parameter to cap XY velocity in POSHOLD, refactored horizontal control to use this parameter, and introduced a function to compute pilot-desired horizontal rates from RC inputs. This enables safer, more predictable POSHOLD behavior under user RC commands. Major bugs fixed: - Addressed bounce-back in POSHOLD stopping by capping XY velocity with PILOT_SPEED, reducing overshoot and improving stop stability under varying RC inputs. (Commit: 2a28b77ef671369cadfb6c94239debb00abcbb0e) Autotest and quality: - Added autotest PosHoldBounceBack coverage to ensure stability and to prevent bounce-back when stopping under varying RC inputs. (Commit: 1df67446f6c48c6bc56df78fd361949d5864fac1e) Overall impact and accomplishments: - Safety and reliability of POSHOLD improved for users operating in RC-driven scenarios, with a clear mechanism to cap speed and maintain stable stopping. - Improved maintainability through parameterization and a dedicated autotest validating bounce-back behavior. Technologies/skills demonstrated: - Control surface refactoring and parameterization (PILOT_SPEED) - RC-input processing and mapping to pilot-desired rates - Autotest development for stability validation - Version control traceability with clear commit messages Repository: ArduPilot/ardupilot Month: 2024-12

Nov 1, 2024Month: 2024-11 — Implemented high-frequency IMU data logging with a new loop_rate_logging task in ArduPilot/ardupilot. This feature is controlled by MASK_LOG_IMU_FAST to enable loop-rate logging and reduces unnecessary IMU logs when fast logging is active by adjusting twentyfive_hz_logging. Scheduler integration supports high-rate data paths while maintaining reliability. Commit reference included: ab46ca2098657a41de21d0cb671b894d06ebd4b1 with message "Sub: support MASK_LOG_IMU_FAST (loop rate logging)".
