Robot tip

Find the topic, use the idea — “decide which lesson a question comes from, then use that lesson’s rule”

  1. Find the topic: robot basics, moving, gears, sensors or programs.
  2. Use that lesson’s rule — sense/think/act, teeth × turns, circumference × turns, 17 cm per ms, follow every line.
  3. Safety answers are always: switch off, stay out of reach, an adult nearby, the emergency stop.

Use it for: Final revision of the course, a robotics club challenge or before starting a real robot project.

Worked example: 📡 A distance sensor sends a sound pulse and hears the echo 5 ms later. Sound travels about 34 cm every millisecond. How far away is the object (in cm)? → 85

  1. The sound goes there and back, so each ms of echo is 17 cm of distance.
  2. 17 × 5 = 85 cm.

Check: 85 × 2 = 170 = 34 × 5 ✓
