Robo-Math How Far? The Distance a Robot Travels in One Rotation of the Motor = The Circumference of the Wheel Circumference (of the Wheel) = Diameter (of the Wheel) X ∏ 3 Questions: How Far will the Robot travel with 720⁰ of rotation? How many Rotations will it take for the Robot to go 50cm? How many Rotations will it take for the Robot to go 25in?

Robo-Math How Far? Step 1) Measure the Diameter of the wheel Step 2) Calculate the Circumference of the wheel Circumference = Diameter X ∏ = __________ X ∏ ≈ __________ X 3.14 ≈ __________

Robo-Math Question A Step 3) Calculate how far robot will go with 720⁰ of rotation Number of rotations = 720 / 360 = 2 How Far = Circumference X Number of Rotations ≈ __________ X 2 ≈ __________ Step 4) Demonstrate: - Measure and draw predicted line - Place Lego Dude on line - Run program

Robo-Math Question B Step 3) Calculate how many rotations to go 50 cm Number of rotations = Total distance / Circumference Number of rotations = 50 cm / __________ = _____ Step 4) Demonstrate: - Place Lego Dude on 50 cm line - Run program

Robo-Math Question C Step 3) Calculate how many rotations to go 25 inches Number of rotations = Total distance / Circumference Number of rotations = 25 in / __________ = _____ Step 4) Demonstrate: - Place Lego Dude on 25 inch line - Run program
