✏️ Drawing Lab

Clip a felt-tip pen to the bot. Spirograph for math, Polygon for geometry, Free for art. Plan it on screen, then let the bot draw it on paper.

📝 Pen-up / pen-down isn't controllable — this is a plan visualizer. The bot draws while it moves.

▲ Polygon

Sides 5

Side length (mm) 80

Angle correction (°) 0

Exterior angle = 360°/sides. Trim it if your bot under- or over-turns.

✸ Spirograph (Hypotrochoid)

Outer radius R 80

Inner radius r 30

Pen offset d 40

Sample points 100

x = (R−r)cosθ + d·cos((R−r)/r·θ)
y = (R−r)sinθ − d·sin((R−r)/r·θ)

✎ Free Draw

Smooth (Catmull-Rom) 0.5

Sample step (mm) 15

Drag on the canvas. Each stroke is sampled at the chosen step then converted to drive+turn moves.

⚙ Calibration

Speed 120

mm / sec 120

°/sec (spin) 180

Pause (ms) 120

Drive a known segment with ▶, time it, adjust mm/s and °/s so the bot tracks the preview.
