PROFILE
Gautier Hattenberger
Gautier Hattenberger developed advanced drone control and simulation features for the tudelft/paparazzi repository over six months, focusing on modularity, reliability, and hardware adaptability. He rewrote the gimbal pan/tilt module, enhanced rover firmware with PID steering, and introduced trajectory execution tools, leveraging C and Python for embedded systems and robotics. His work included robust GPS/GNSS parsing with Galileo RTCM support, actuator telemetry improvements, and safer INDI command handling. By refactoring network and PWM configuration, improving sensor calibration, and enabling alternative control models, Gautier delivered maintainable, cross-platform solutions that improved flight safety, platform flexibility, and operational efficiency across diverse drone hardware.

Feb 1, 2026February 2026 monthly summary for tudelft/paparazzi: - Delivered a modular stability and guidance framework enabling alternative control models (Hinfinity) and tilted-motor support for hexacopters, enhancing lateral motion control and adaptability. (Commit 37a86bb389176c9d79913d9c322398aab6b151db) - Implemented Galileo RTCM 1097 support with updated airborne parsing and robust GPS data handling; added fixes to prevent data overflow and ensure correct packet sizing. (Commit 5aa3d5f368bb9af4f907bde1307278519c1e89f1) - Added INDI controller command vector configuration with safe defaults and backward compatibility, including an example airframe and explicit failsafe values. (Commit 979c01cd7c8efe1239d7ffa5a23783cf2bb6ea9b) Major bugs fixed: - Prevented data overflow and garbage data in GPS processing by changing RTCM offset type to uint16 and tightening packet size checks (part of the RTCM improvement). (Commit 5aa3d5f368bb9af4f907bde1307278519c1e89f1) - Refactored ground tool rtcm2ivy to support robust RTCM parsing and prevent edge-case failures in Galileo workflows. (Associated improvements in the RTCM stack) - Safer INDI command handling for KILL/failsafe modes with explicit keyword mappings (MOTOR_STOP, MOTOR_IDLE, etc.) to avoid misconfigurations. (Commit 979c01cd7c8efe1239d7ffa5a23783cf2bb6ea9b) Overall impact and accomplishments: - Significantly enhanced platform flexibility and airframe adaptability, enabling more capable multirotor configurations and new control models. - Improved GPS data reliability and integrity in Galileo-enabled scenarios, reducing data loss and mis-sizing issues. - Streamlined configuration and safer operation through INDI-driven command vectors with explicit failsafe semantics, improving on-vehicle safety and maintainability. Technologies/skills demonstrated: - Modular control architecture and Hinfinity-style guidance integration; advanced multirotor modeling. - GNSS/RTCM data handling, Galileo support, and robust parsing with safety hardening. - INDI protocol integration, safe-defaults design, backward compatibility, and airframe-level configurability.

Sep 1, 2025In September 2025, delivered two major feature streams for tudelft/paparazzi: a rewrite of the Gimbal Pan/Tilt Control Module and enhancements to the ROVER firmware and simulator. The Gimbal rewrite provides a generic, configurable pan/tilt controller with multiple built-in modes, per-gimbal specialization (e.g., Caddx GM3), and cleanup of unused legacy code, enabling easier integration with a range of gimbals and improved reliability. The ROVER enhancements introduce basic PID control for steering, navigation fixes, mission mode support, plus simulator orientation alignment and two-wheeled rover support with updated configuration files. These changes improve hardware compatibility, autonomy reliability, and simulation fidelity, delivering measurable business value in safer field operations, reduced maintenance, and faster platform onboarding.
