Determine+Turn+Circle+Circumference+2

1. Define circumference. The distance around a circle like a wheel.

2. Explain what the "Turn Circle Circumference" of a wheeled Robot is. Is it distance, rotations, or degrees. In a swing turn only one wheel rotates..

3. Block Control Panel Screen Shot reasonably cropped.

4. Explain which of the two equations you will use first. Tell which and why. Think about units. distance = W Circumference x Rots will be used. This equation contains rotations so it is the only one that can be use.

5. Equation showing the correct numbers in the correct places. Use the equation that deals with distance and not turning. Look at the units.


 * __Distance__ ||  || = ||   || __17.584cm__ ||   || X ||   || __4.3__ ||
 * 1 ||  ||   ||   || 1 ||   ||   ||   || 1 ||

Wh Cir = 2(2.8cm)3.14 Wh Cir = 17.584cm

6. Solve the equation for distance. Distance = 75.61cm

7. Put this distance in the correct place in the equation that deals with turning. This distance will turn your robot 360 degrees, so this is the "Turn Degrees." Put this in the correct place in the equation. Circumference || 8. Now look at the equation. On the left, the top divided by the bottom equals one. In other words the left side cancels to the number 1. On the right we have a number which is then Turn Distance in centimeters over the words: Turn Circle Circumference. If we multiplied both sides of the equation by the words, "Turn Circle Circumference" we get:
 * __360 Degrees__ ||  || = ||   || __75.61cm__ ||   ||   ||   ||   ||
 * 360 Degrees ||  ||   ||   || Turn Circle

Turn Circle Circumference = the "Turn Distance in centimeters" which is a number.

This means the distance you got for a 360 degree turn is the Turn Circle Circumference.

9. Tell what the robot's Turn Circle Circumference is by completing the following. Turn Circle Circumference = 75.61cm
