PROFILE
John Keller
Worked on the AirStack repository, delivering advanced robotics and drone control features with a focus on autonomous flight, simulation, and deployment reliability. Developed and integrated modules for trajectory planning, behavior trees, and real-time data visualization, leveraging C++, Python, and ROS/ROS2. Enhanced system stability and observability through containerized environments using Docker, robust logging, and automated configuration management. Implemented 3D graphics and OpenGL-based perception nodes for improved operator insight and debugging. Addressed deployment and runtime challenges by refining build systems, environment configuration, and documentation, resulting in safer, more reproducible workflows and streamlined integration from simulation to real-world robotic operations.

Jan 1, 2025January 2025: Delivered a robust, Docker-based Ground Control Station environment for AirStack with separate simulation and real-robot configurations, consolidating the base setup while improving network handling and ROS_DOMAIN_ID management. Implemented MAVROS integration for drone communication and fixed trajectory controller issues to improve end-to-end reliability from simulation to real flights. Completed packaging consistency by bumping version to 1.0.4. Addressed key stability improvements through targeted bug fixes: dockerfile bug fix, corrected docker-compose command typo, and added bashrc error handling to detect missing robot IDs and surface clear errors when the ROS_DOMAIN_ID is invalid.
