Programming, Controls & SensorsModule 12 of 13

Advanced Techniques and Case Studies

Once the fundamentals are solid, top teams reach for techniques that squeeze out reliability and precision: model-based state-space control with Kalman filtering, log-replay architectures like AdvantageKit that let you debug a match offline, advanced multi-tag pose fusion, robot-to-robot coordination, and rigorous pre-event software hardening. This module goes deep on those advanced controls and software-engineering practices, with real WPILib/vendor APIs and concrete case studies, so an experienced programmer can level up from 'it works' to 'it works every match, and we can prove why.'

Advanced Techniques and Case Studies closes the Programming, Controls & Sensors guide as module 12 of 13, after Common Mistakes and Troubleshooting. Its 5 lessons are about 215 minutes of the guide's ~30 hours.

01State-Space Control and Kalman FilteringGo beyond PID with model-based control: an LQR controller, a Kalman filter observer, and a LinearSystemLoop for a flywheel.50 min read

02Log Replay Architecture with AdvantageKitRecord every input to your robot code and re-run it bit-for-bit offline, so you can debug a real match from your couch and verify fixes deterministically.40 min read

03Advanced Pose Estimation: Multi-Tag Fusion and Standard DeviationsTune how much your estimator trusts vision vs. odometry, fuse multiple AprilTags, and reject bad measurements for centimeter-level field localization.45 min read

04Robot Coordination, Alerts, and Operator FeedbackProduction-grade habits: surface faults with the Alerts API, drive LEDs as status, and build operator feedback so problems are visible before they cost a match.40 min read

05Case Study: Hardening Software Before an EventA pre-competition software checklist drawn from real failure modes: preemptive checks, fail-safe defaults, deterministic autos, and version control discipline.40 min read
