When a circular wheel with a radius r is rolled over a horizontal line as shown in the figure, the coordinates at which the contact point between the wheel and the horizontal line moves can be expressed using the center angle t (radian).

a = r*sin(t)
b = r*cos(t)

x = r*t - r*sin(t)
y = r - r*cos(t)
