Robotics Worksheet: Wheel Distance

Robotics lesson 15: Wheels and distance · Set 989 · 40 questions

Robot tip (Circumference × turns): Circumference = π × diameter (= 2 × π × radius). Use π = 22/7 for 7, 14, 21 … cm, or π = 3.14. Distance = circumference × turns. Turns = distance ÷ circumference. With gears, find the wheel’s turns first.
