1. 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?

2. 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. 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

4. 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

5. 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
