Calculating a Zig-Zag Course a) travel a distance, b)turn, c) travel a second distance, d) turn again, and e)drive off the course.

Wheel Circumference = 3.14 x 5.5cm = 17.27cm Traced Circle Circumference = 3.14 x 25 = 78.5cm

__ A. The first distance is 9.7 cm __. Step 1: 9.7cm = 17.27 x Rotations

0.562 = Rotations

Step 2: 0.5617 x 360 = program degrees

202 = program degrees

__ B. The first turn is 37 degrees. __ Step 1: __37__ = __Distance__ 360. 78.5cm

37 x 78.5cm = 360(Distance)

8.07cm = distance

Step 2: 8.07cm = 17.27cm x Rotations

0.467 = Rotations

Step3: 0.467 x 360 = program degrees

168 = program degrees

__ C. The second distance is XXXcm. __ Step 1: XXXXcm = 17.27cm x Rotations

XXXXX = Rotations

Step2: XXXXXX x 360 = program degrees

525 = program degrees

__ D. The second turn is 98 degrees. __ Step 1: __ 9XX __ = __ Distance __ 360. 7XX.5cm

9XX x 7XXcm = 360(Distance)

XXXcm = Distance

Step 2: XXXXcm = 17.27cm x Rotations

XXXXX = Rotations

Step3: XXXXX x 360 = program degrees

XXXXX = program degrees

__E. Program the robot to drive straight for 720 program degrees__. (Two wheel rotations)
