Circumference = 3.14 x diameter

__Turn Angle__...... = __Distance wheel needs to turn__ 360 Full Circle......Circumference of the Traced Circle

Distance = Wheel Circumference x rotations

Wheel diameter of 6.5 cm / Wheel Circumference 3.14 x 6.5 cm = 20.41 cm T-Circle of 25 cm / T-Circle Circumference 3.14 x 25 cm = 78.5 cm

Make the robot turn 27 degrees: Step 1: Distance one wheels needs to go to make the turn. __27..__ = __X__ 360 . 78.5

360X = 27cm x 78.5cm

__360__X = __27cm x 78.5cm__ 360 ...........360

x = 5.88 cm

Step2: Find rotations required to make the turn.

__5.887 cm__ = __20.41 cm__ x Rotations 20.41 cm .. 20.41 cm

0.2884 = Rotations

Step 3: Change rotations to program degrees

__360.........__ = __X......__ 1 rotation. 0.2884 rotations

360 x 0.2884 = X

103.8 or 104 = program degrees

__Now let us turn the same robot 54 degrees.__

__54..__ = __Distance__ 360 .. 78.5 cm

360(distance) = 54 x 78.5 cm

__360(distance)__ = __54 x 78.5 cm__ 360 ........................360

Distance = 11.775 cm

Step 2: Find Rotation

11.775 cm = 20.41 x Rotations

__11.775 cm__ = __20.41 x Rotations__ 20.41 cm .. 20.41

0.5769 = rotations

Step 3: Find program degrees 0.5769 x 360 = 207.7

What was our program degrees for 27 degrees and 54 degrees? .........................................................103.8 ........... 207.7

27 x 2 = 54 Short Cut: 103.8 x 2 = 207.6
