June 2026 performance for peterbarker/ardupilot focused on stabilizing autonomous terrain interactions, expanding frame support, improving simulation fidelity, and strengthening test reliability to shorten feedback loops and improve mission safety. Key work spanned terrain recovery hardening, waypoint frame handling, SITL range simulation, guided waypoint testing, and autotest cleanup to reduce flakiness and maintenance burden.

April 2026 monthly summary for the peterbarker/ardupilot project focusing on underwater flight control additions. Delivered a new Submersible Descent Control capability by introducing the dive() method to control descent to a specified altitude. This change refactors altitude handling to route through dive(), aligning with existing mode and throttle adjustments for dives and paving the way for more robust underwater mission profiles. Expanded the testing framework to include autotest coverage for diving operations.

Month: 2026-03 focused on cleaning up deprecated Bluerov2 parameter files in ArduPilot to improve configuration reliability and reduce maintenance overhead. Delivered targeted codebase cleanup, removing outdated settings to prevent configuration drift and simplify future updates.

December 2025: Targeted documentation improvement in ArduPilot/ardupilot focusing on servo output constants for AP_JSButton. This non-breaking change clarifies current behavior by correcting comments and aligning documentation with actual code, without introducing runtime changes.

May 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.

March 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.

December 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

Month: 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)".

September 2024 monthly work summary for the peterbarker/ardupilot repository, focusing on reliability, safety, and maintainability improvements in the autopilot stack.
