Design a track for Evo. Use what you know about the relationship between distance, time and speed to determine how fast Evo can get around your track.
Hint: when you ride in a car, speed is measured in miles per hour (mph)

Directions:
Take a blank sheet of white paper and USING THE PENCIL OR PEN draw a track for Evo around the outside perimeter.
Measure each side of the track and calculate the exact perimeter.
Trace over your pencil/pen version using the black marker. Hint: go back and make sure the line thickness is consistent throughout the entire path.
Make a mark for the beginning of your track.
Place your Ozobot Evo at the beginning and press his Power button. Time him as he runs your track.
Use what you know about the relationship between distance, time and speed to determine how fast Evo travels in centimeters per second.
Extension: Create another track. DON'T MEASURE THE DISTANCE! Have Evo complete a lap on the track. Don't forget to time how long it takes. Using what you now know about how fast Evo travels, calculate the distance of your track.
Extension 2: Try adding different features to your track. Do turns make Evo go slower or faster? Does adding a code before a turn affect how fast Evo can navigate a turn?
Extension 3: What is the maximum number of speed codes that can be added to your track to get the best time out of Evo? Which combination of codes results in the slowest time?
