For a robot to do a turn first the "turn distance" and then the "rotations" must be calculated.
Equation/Formula
Turn degrees

=

Turn Dist


360 degrees



Turn Circle Cir


Turn robot 10 degrees:
10 degrees

=

Turn Dist


360 degrees



75.61cm


(Above is aaaaaaaaaaaaaaaaaa)
Divide top by bottom on the left:

0.028
=

Turn Dist






75.61


Multiply both sides by 75.61cm

2.10 cm = Turn Distance
(Above is bbbbbbbbbbbbbbbbbb)

Equation/Formula
Distance = Wheel Cir X Rotations

2.10 cm = 17.58 cm x Rotations
Divide both sides by 17.58 cm
(Above is ccccccccccccccccccccc)

0.119= Rotations
(Above is dddddddddddddddddd)


Calculate a turn for 80

80 degrees

=

Turn Distance


360 degrees



75.61 cm


On the left divide the top by the bottom.

0.2222

=

Turn Distance






75.61 cm


Multiply both sides by 75.61cm
16.80 cm = Turn Distance

Distance = Wheel Cir X Rotations
16.80 cm = 17.58 cm X Rotations
Divide both sides by 17.58 cm
0.9556 = Rotations
