What is this tool?
If an encoder reports CPR counts per revolution, distance per count is the mechanical travel per revolution divided by CPR (wheel circumference or leadscrew pitch). Summing counts estimates travel — slip and quantization still apply.
How to use it
- Enter CPR and wheel diameter or linear pitch.
- Convert counts → distance or distance → counts.
- Calibrate on the real robot when accuracy matters.
