Learnsy lessons
Interactive technical intuition
Standalone lessons that pair concise theory with browser-based simulators. Open a lesson directly and tune the system while reading what each scenario is meant to show.
PID Controllers
Control a motorized arm with a hanging weight. Tune Kp, Ki, and Kd to see offset, ringing, damping, windup, and disturbance response.
Kalman Filters
Track a delivery robot through noisy GPS, odometry drift, and signal loss. Compare Kalman filtering against raw GPS, moving average, and dead reckoning.
