Mackie worked on the tier4/AWSIM repository, delivering features and fixes that enhanced simulation fidelity, onboarding, and developer experience. Over eight months, Mackie implemented autonomous vehicle control modes, improved Logitech G29 input handling with PID-based torque and JSON configuration, and refactored Unity URP scenes for stability. Using C#, Unity, and Git, Mackie synchronized vehicle input with physics updates, introduced resistive force modeling, and maintained rigorous documentation and CI/CD hygiene. The work included updating demo data, consolidating contributor guidance, and establishing governance with CODEOWNERS and Git Flow. Mackie’s contributions demonstrated technical depth and improved both simulation accuracy and project maintainability.

12 Commits • 3 Features
Oct 1, 2025October 2025 focused on enabling autonomous operation, strengthening hardware input fidelity, and solidifying scene stability in AWSIM. Key outcomes include an autonomous control mode switch mapped to a Logitech G29 button, a configurable G29 input stack with PID-based self-aligning torque and JSON-tunable parameters, a URP Unity scene refactor to fix camera/link integrity, and targeted fixes to improve demo reliability. Notable improvements include disabling RTC in AutowareSimulationDemo to reduce overhead and a bug fix for stationary steering resistance. The work enhances simulation fidelity, accelerates autonomous testing, and reduces manual configuration time.
