Robotics Worksheet: Final Test

Robotics lesson 30: Final robotics test · Set 37 · 40 questions

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