Lessons and supplementary material

If this is your first visit, start with K0 · Why system identification matters, read K1 · System identification fundamentals, then continue to L0 · Estimate joint inertia and damping.

Once those ideas are familiar, continue to L1 · Actuator delay and friction. Each lesson brings its explanation, evidence status, exercises, and conclusions together on one page; a video appears only when its named teaching question is marked available.

L1 now includes a second isolated actuator experiment on friction versus viscous damping, delivered through the same lesson page with a local CPU report and notebook.

Find a lesson

The course directory shows knowledge lessons, synthetic experiments, and hardware experiments. Formal pages now cover K0–K8, L0, L0-E, L1, L1-O, L1-S, and L2–L6. The course map distinguishes Concept, Runnable, and Design draft; numerical reports and simulator evidence are linked only where they exist. Hardware lessons remain marked “Coming later”.

Explore an experiment

The L0 supplementary material and L1 supplementary material provide focused notes, reports, notebooks, and local apps.
