Brody Dai developed advanced autonomous navigation and control features for the SalineSingularityFRC/2025-Reefscape robotics repository, focusing on reliable mission execution and subsystem coordination. Over six months, Brody architected and refined command-based routines, integrating Java and JSON for configuration and leveraging computer vision with RealSense cameras to enable robust pose estimation and vision-based navigation. He implemented velocity-controlled conveyor systems, PID-tuned elevator and intake subsystems, and reusable autonomous paths to improve throughput and repeatability. By addressing subsystem concurrency, state management, and operator feedback, Brody delivered maintainable, testable code that reduced manual intervention, increased safety, and enabled rapid iteration for complex autonomous tasks.

Apr 1, 2025Monthly Summary — SalineSingularityFRC/2025-Reefscape (April 2025) Overview: Focused on advancing autonomous perception, precise actuation, and reusable autonomous routines to improve mission reliability, throughput, and repeatability in reef-scape robotics. Delivered camera-driven pose estimation enhancements, refined vision-based navigation, precision conveyor control, and a set of predefined autonomous paths. These changes reduce setup time for autonomous runs, improve consistency across missions, and enable more predictable scoring and throughput. Key deliverables and business value: - Camera-driven autonomous navigation and pose estimation improvements: Refined RealSense camera pose handling, integrated into autonomous scoring, and added PoseAndTarget data support to stabilize vision-based navigation. This enables more reliable reef-target driving and reduces operator intervention during runs. - Conveyor belt velocity control for precise movement: Migrated to velocity-based control using SparkClosedLoopController with setReference and ControlType.kVelocity, delivering tighter speed regulation and improved material throughput consistency. - Predefined autonomous navigation paths: Introduced Choreo Paths with waypoint-based constraints to support repeatable, complex autonomous routines, accelerating mission setup and reducing manual calibration. - Minor stability fix: Addressed translation2d handling for NetworkTables to improve data consistency and reduce localization jitter during operation. Impact and outcomes: - Increased autonomy reliability and scoring accuracy through robust pose estimation and vision-based navigation. - Improved throughput stability and predictability of conveyor operations, contributing to higher mission efficiency. - Faster deployment and repeatable autonomous routines via predefined paths, enabling better planning and execution of reef-scape missions. Technologies and skills demonstrated: - Computer vision and sensor fusion (RealSense pose estimation, PoseAndTarget integration) - Robot control and feedback (SparkClosedLoopController, velocity control) - Path planning and autonomous routines (Predefined choreographies/Choreo Paths) - Data handling and system stability (NetworkTables translation2d fixes)
